• 1906: A film based on the 2004 historical novel was planned as early as when author James Dalessandro was researching 1906 as a prequel to his novel Bohemian Heart and he made a 38-page outline and six chapters of his novel when he found out the success of Titanic.^[1] Warner Bros. Pictures had the script sold despite other companies entering in a bidding war.^[2] Due to the big budget, Warner Bros. partnered up with Walt Disney Pictures and Pixar and it would have been the first time Pixar has been involved in a live-action film and the first time Pixar collaborated with a major production company other than Disney with Brad Bird directing though eventually he left the project due to working on Ratatouille.^[3] Warner Bros. reserved all sound-studios available on their Burbank lot for production.^[4] However, later that spring, Warner Bros. quietly released the reservations while Brad Bird continued rewriting the screenplay in order to lessen the massive scope of the story.^[5] In 2011, it was reported by Brad Bird that the film project was still being developed. The issues he raised was his difficulty in narrowing the scope of such a manner as to be true to the story within the constraints of practical film length.^[6] In February 2012, it was revealed that a rewrite of Dalessandro's script had been completed by Michael Hirst, and Brad Bird was now rewriting it yet again.^[7] In June 2018, Bird mentioned the possibility of adapting the book as a TV series and the earthquake sequence as a live-action film.^[8]

• Alien vs. Predator: Alien vs. Predator was first planned shortly after the 1990 release of Predator 2, to be released sometime in 1993. The production stalled for more than a decade, with frequent actor changes, restarts, and failed promotions of the film until its eventual release in 2004.^[12]
• Alita: Battle Angel: James Cameron's live-action adaptation of Yukito Kishiro's manga series Battle Angel Alita was in development hell starting in the early 2000s. The project was finally completed under the direction of Robert Rodriguez and released in 2019.^[13]

• At the Mountains of Madness: Since 2006, Guillermo del Toro and Matthew Robbins wrote a screenplay based on H. P. Lovecraft's story but had trouble getting Warner Bros. to finance the project because Del Toro claimed that the studio was very nervous about the cost and it not having a love story or a happy ending (either of which is impossible to do in a Lovecraft story).^[24] In 2010, it was announced to be a 3D film and James Cameron would be a producer while Tom Cruise would star in the film.^[25] It was reported that Universal Pictures refused to green light the project due to del Toro wanting an R rating while the heads at Universal wanted a PG-13 rating.^[25] Later on, the film was pitched to Netflix after signing a multi-year deal with the streaming service in 2020. The script was rewritten to make it a smaller, weirder, and more esoteric version in respect of the scenes that he has left out before.^[26] Del Toro later stated that Tom Cruise feels too old to star in the film.^[27] Del Toro also stated that the film could be a stop-motion film.^[28]
• Atuk: A film adaptation of the novel The Incomparable Atuk. Norman Jewison first purchased the film rights in 1971, and since then there have been several attempts to produce it.

• Barbie: The idea of a live-action Barbie film had been in development at Cannon Films in the mid-1980s; little is known about it, other than a promotional blurb (with the plotline centering around Barbie showing her owner how all her dreams could come true), and it is unclear how far into development it got before Mattel ceased working with Cannon, following Cannon's live-action adaptation of Masters of the Universe (1987) flopping at the box-office.^[33] Development on a film based on the Barbie toy line began in September 2009, when it was announced that Mattel had signed a partnership to develop the project with Universal Pictures and with Laurence Mark as producer, but nothing came to fruition.^[34] In April 2014, Mattel teamed with Sony Pictures to produce the film, which would have Jenny Bicks writing the screenplay and Laurie MacDonald and Walter F.

Pictures in October 2018.^[42][43] Margot Robbie was cast as the lead in 2019, after Gal Gadot turned down the role due to scheduling conflicts, and Greta Gerwig was announced as co-writer with Noah Baumbach before being confirmed as director in 2021.^[44][45] The film was released on July 21, 2023, and it, alongside Oppenheimer, was a major commercial success.

The pressure of having to save the world, their marriages are falling apart, their kids are kind of mad at them, and then someone comes from the future and tells them if they don't write the song it's just not the world, it's the universe. So they have to save the universe because time is breaking apart".^[61] During the New York City Comic Convention, Reeves revealed that the title would be Bill & Ted Face the Music.^[62] The film was released on August 28, 2020.^[63][64]

• The Black Cauldron: Walt Disney Productions optioned Lloyd Alexander's five-volume book series in 1971, acquired the rights to Alexander's novels The Chronicles of Prydain, and began development of the movie in 1973. The release date was delayed several times. In July 1978, the studio pushed back the release date to Christmas 1984 due to their inability to animate realistic human characters, which caused The Fox and the Hound to be released in 1981. Re-production of The Black Cauldron began in 1980. Shortly before the film's initially planned 1984 theatrical release, a test screening of the rough cut of the film was held at the studio, but was met with negative feedback that claimed it was too intense and disturbing for the majority of the children in the audience, particularly during the climactic 'Cauldron Born' sequence. The newly appointed Disney studio chairman Jeffrey Katzenberg ordered certain scenes to be removed to calm things down. When producer Joe Hale objected to Katzenberg's demands, Katzenberg responded by taking the film and editing it himself. After Michael Eisner heard from Hale what Katzenberg was doing, he called him in the edit room and convinced him to stop. Though he did what Eisner told him, he requested that the movie should be modified and delayed from Christmas 1984 to July 24, 1985, so that the movie could be reworked. After 14 years of development, the movie was released on July 24, 1985, receiving mixed reviews from critics and becoming a box-office bomb.^{[citation needed]}

This would have been an origin story of the show hosts Bob the Tomato and Larry the Cucumber which would have revealed how they got their show made and would have explored how the fruit and vegetables were able to talk. This would have featured humans in the film and would've be the first VeggieTales-related media to do so.^[67] After the box office bomb of Jonah: A VeggieTales Movie, Big Idea Entertainment fell into bankruptcy and the film got put on a hiatus due to the film's budget. In 2008, it was considered to be the sequel to The Pirates who Don't Do Anything: A VeggieTales Movie, but talks stalled after the 2008 recession had led to the bankruptcy of VeggieTales owner Entertainment Rights and Classic Media. Series creator Phil Vischer claims that he has a copy of The Bob and Larry Movie on his laptop but can't share it due to being owned by Universal Pictures and DreamWorks Animation.^[68] However, Big Idea is facing limbo due to problems going on which led to the departure of some key members of Big Idea thus putting the film in limbo.^[69]

• Captain Planet and the Planeteers: Multiple attempts have been made to create a film adaptation based on the environmentalist superhero cartoon series.

Burton was still being courted to direct. Waters joked that "turning it in the day Batman Forever opened may not have been my best logistical move, in that it's the celebration of the fun-for-the-whole-family Batman. Catwoman is definitely not a fun-for-the-whole-family script".^[93] In an August 1995 interview, Pfeiffer reiterated her interest in the spin-off but explained her priorities would be challenged as a mother and commitments to other projects.^[94][95] Ashley Judd as the lead in 2001,^[96][97] but she eventually dropped out^[98] so Nicole Kidman was considered.^[99] When Warner Bros. canceled a Batman vs. Superman film scheduled for 2004, the studio decided to quickly produce Catwoman as replacement, starring Halle Berry.^[100] Berry chose to be involved with the film after the cancellation of Jinx, a James Bond spin-off featuring her character Giacinta "Jinx" Johnson from Die Another Day (2002).^[101] Josh Lucas was considered for the role of Tom Lone.^[102]

It was scrapped due to the film's box office reception and mixed reviews from critics. In 1980, animators Wolfgang Reitherman and Mel Shaw worked on a spiritual successor to Fantasia titled Musicana which would've mixed jazz, classical music, myths, modern art, etc. The idea of a Fantasia sequel was revived shortly after Michael Eisner became chief executive officer of The Walt Disney Company in 1984, when Walt's nephew, vice chairman Roy E. Disney, suggested it to him at a lunch.^[179] André Previn was at one point going to work on the sequel but refused to do so after learning that the sequel would feature songs from The Beatles rather than typical classical music. It took a further seven years before the film was reconsidered, after the 1990 reissue of Fantasia grossed $25 million domestically and the announcement of its limited availability on home video in 1991 prompted 9.25 million pre-orders. Disney saw its commercial success as a sign that there was enough public interest in the Fantasia franchise to make a sequel. Eisner finally gave the green-light to the film in 1991, and had Disney serve as executive producer on the basis that its production was funded by the proceeds from the video sales. Production began under the working title Fantasia Continued but was changed to Fantasia 1999 and later Fantasia 2000. It was originally going to be a "semi-new movie" where it would feature most segments from the original Fantasia with only a few new segments but it didn't work out well so the older segments had to be trimmed down to three consisting of The Sorcerer's Apprentice, The Nutcracker Suite, and Dance of the Hours. The former was chosen eventually as the only returning segment to feature in 2000. There was even some unused segments that were meant to be in the final film which include Clair de Lune and Rhapsody on a Theme of Paganini. The film was officially announced on February 9, 1999 and was released on January 1, 2000 via IMAX and June 16, 2000 in the United States.
• The Flash: Development of a film based on the comic book character of the same name began in the late 1980s when Warner Bros. hired comic book writer Jeff Loeb to write a treatment.^[180] The project was later revived in December 2004 when David S. Goyer was brought on to write, direct, and produce a new version of The Flash after penning the script for Batman Begins.^[181] After Goyer left the project in February 2007 over creative differences, Shawn Levy was hired to direct with a new draft written by Chris Bancato,^[182] before both abandoned the project in October 2007 and David Dopkin was hired to revamp it as a spin-off to George Miller's then-planned film, Justice League: Mortal, with Adam Brody cast as the character.^[183] Justice League: Mortal was later cancelled and the film was stuck in further development caused by the 2007-2008 Writers' Guild of America strike.^[184] Warner Bros. began development again as part of their newly established DC Extended Universe in July 2013, with a planned release date of 2016.^[185] In October 2014, Ezra Miller was cast as the character, with a theatrical release planned for March 23, 2018.^[186] Miller portrayed the character onscreen in Batman v Superman: Dawn of Justice (2016), Suicide Squad (2016), and Justice League (2017). Several directors, including Seth Grahame-Smith, Rick Famuyiwa, and filmmaking duo John Francis Daley and Jonathan Goldstein, left the project over creative differences at various points from 2016 to 2018. Christina Hodson and Andy Muschietti were confirmed to be writing and directing, respectively, in November 2019.^[187] Pre-production began in January 2020, with Principal photography lasting from April to October 2021 at Warner Bros. Studios, Leavesden. After multiple post-production setbacks and controversies surrounding Miller, the film was released on June 16, 2023, and became a commercial failure.
• Foodfight!: In 2004, the CGI film Foodfight was announced. Described as "Toy Story in a supermarket", the film promised to bring together over 80 famous advertising characters with voice talent including Charlie Sheen, Christopher Lloyd, Eva Longoria, Hilary and Haylie Duff, and Wayne Brady. Director Lawrence Kasanoff expected it to be a commercial hit and merchandise for the movie appeared on store shelves before the film had a release date. However, the film ran into many problems.^[188] In late 2002/early 2003, Kasanoff reported that hard drives containing unfinished assets from the film had been stolen in what he called an act of "industrial espionage." However, those who worked on the film did not recall this happening, with one assistant claiming that the original hard drives were saved and stored properly and believed that Kasanoff was simply not satisfied with them. A behind-the-scenes showreel Kasanoff put together to entice investors is the only significant surviving footage of the original incarnation of the film.^[189] After several years, a trailer^[190] was finally shown at AHM in 2011, a company bought the DVD distribution rights for the film in Europe,^[191] and a quiet video-on-demand American release came in 2012.
• Freddy vs. Jason: A crossover between Freddy Krueger and Jason Voorhees was first attempted in 1987, but fell apart due to disagreements between Paramount Pictures and New Line Cinema, the respective owners of Friday the 13th and A Nightmare on Elm Street.^[192] After the release of Jason Goes to Hell: The Final Friday, which teased Freddy vs. Jason, New Line Cinema spent roughly $6 million on several unused scripts from over a dozen screenwriters, but eventually, Mark Swift and Damian Shannon produced a script that went into production. The film experienced controversy when it was announced Kane Hodder, the longtime actor for Jason, was to be replaced by a different actor, and experienced further controversy when it was revealed that the original 120-page script was to be cut down by a different writer. Both Swift and Shannon had to deal with studio interference and hesitation, as well as fighting a PG-13 rating and having to send out a questionnaire to gauge interest in the concept.^[193] Finally, the film released on August 15, 2003, and grossed $116.6 million worldwide on a production budget of $30 million to a mild critical response.^[194][195]
• Frozen: Beginning development in 1940 as a biopic about Hans Christian Andersen's life,^[196] progress on the Disney–Goldwyn project halted in 1942 as the United States entered World War II, with Disney shifting its focus to wartime propaganda. Between 1992 and 2002, Disney attempted a revival of the project, with multiple versions of the film now stored in their Animation Research Library. These versions removed key elements such as a troll and a mirror, requiring creative solutions for the character Kai's departure. Attempts included a story line in Iceland where Kai joins a whaling ship to impress Gerda, while the Snow Queen rides an orca. Other versions experimented with adding comic side characters to the narrative but no one was able to transform the minimally defined characters and episodic plot into a compelling narrative. That was until it was put back into production in 2008 with Chris Buck and Jennifer Lee as directors and was released in 2013.^[197]

Goyer were confirmed to be working on a Hellraiser remake in May 2019, and in 2020 David Bruckner, Ben Collins and Luke Piotrowski were also confirmed to be directing and writing the script.^[203][204] In October 2021, principal filming finally wrapped up; it was revealed that Jamie Clayton was to be playing Pinhead and the film was coming out on Hulu.^[205]
• The Incredible Mr. Limpet: Development for a remake of the 1964 film of the same name started in 1996 with Jim Carrey in the lead role and Steve Oedekerk as director. By March 1999, Oedekerk left the project following creative differences, while Carrey followed suit in July the same year.

Vajna bought the rights for Walt Disney Studios via Cinergi Pictures, with a view to create a competitor to the original Star Wars trilogy and Conan the Barbarian.

The project collapsed when McTiernan realized that visual effects were not yet advanced enough to recreate Burroughs' vision of Barsoom.^[220] The film was picked up at Paramount Pictures in the early 2000s and several directors, Robert Rodriguez, Kerry Conran, and Jon Favreau, came and exited the project before Paramount decided not to renew the film rights.^[221][220] Eventually filmmaker Andrew Stanton lobbied Disney to reacquire the rights, and he was hired as director for his live action directorial debut.^[222] The film was released in 2012 as one of the most expensive films ever, and was a notorious flop at the box-office.

• The Legend of Zelda: Since 2007, Nintendo's Zelda series faced plans for a film adaptation. The earliest was when Imagi Animation Studios wanted to make an animated film adaptation of the video game franchise and thus made a pitch reel for a CGI Zelda movie. However, their version of the film got cancelled due to Nintendo not wanting to repeat the same mistakes as what happened with the live-action Super Mario Bros. film.^[225] In 2013, Eiji Aonuma talked about how he wanted to make an interactive Zelda movie where players could bring their Nintendo 3DS into the cinema and players can participate in the film somehow.^[226] Around June 2023, there were rumors suggesting that after the success of The Super Mario Bros.

• Live 2 Tell: A film based on the rapper Tupac Shakur's screenplay that he had written during his incarceration in 1995, about a drug dealer's tale of redemption.^[231] The project goes back to 2005, where IMDb listed it as currently in-production pending further development.^[232] No information was published until 2011 when a company named NStar Studios picked up the project and planned to put it into production in 2012.

• Mad Max: Fury Road: In 1995, George Miller re-acquired the rights to future Mad Max films from Warner Bros.^[235] The idea for a fourth instalment occurred to Miller in August 1998 when he was walking in an intersection in Los Angeles.^[236] About a year later, while travelling from Los Angeles to Australia, the idea coalesced. Miller conceived a story where "violent marauders were fighting, not for oil or for material goods, but for human beings."^[236] The film was set to shoot in 2001 through 20th Century Fox, but was postponed because of the September 11 attacks that same year.^[237] "The American dollar collapsed against the Australian dollar, and our budget ballooned", Miller said, adding that he "had to move on to Happy Feet because there was a small window when that was ready". Mel Gibson, who starred in the original three previous films, would not return to his role as the lead character. Miller ended up re-casting the role because of controversies surrounding Gibson and because he wanted Max to remain at a younger age, as the "same contemporary warrior".^[236] Miller announced in 2003 that a script had been written for a fourth film, and that pre-production was in the early stages.^[238] The project was given the green light to begin filming in the Australian desert in May 2003 with a budget of US$100 million, but the location was ruined by rainfall. Mad Max 4 then entered a hiatus in light of security concerns related to its Namibian shoot because of tightened travel and shipping restrictions at the onset of the Iraq War.^[239][240] In 2007, after focusing on the animated musical comedy Happy Feet, Miller decided to pursue the project again. He briefly considered producing Fury Road as an animated film but abandoned it in favor of live-action. In 2009, Miller announced that filming would begin in early 2011. Tom Hardy was cast as the title character in June 2010, with production planned to begin that November. Principal photography was delayed several more times before beginning in July 2012. The film wrapped in December 2012, although additional footage was shot in November 2013. The film was finally released on May 15, 2015, to critical acclaim, although after the release of the film in question, there has been an ongoing pay dispute between Warner Bros. and Miller as to producing future sequels.

• Untitled Who Framed Roger Rabbit sequel: Plans for a Roger Rabbit sequel was as early as 1989 where J. J. Abrams wrote a script yet it was eventually abandoned.^[424] Nat Mauldin wrote a prequel titled Roger Rabbit: The Toon Platoon (later renamed as Who Discovered Roger Rabbit) which would still feature characters from The Golden Age of American animation and it would have had Roger live on a farm during his early days and traveling to the west to seek his mother.^[425] He also meets Jessica who happens to be his future wife. Roger was also going to be in the army while Jessica was kidnapped to do pro-Nazi Germany broadcasts and thus Roger and new character Ritchie Davenport goes on a quest to save her and thus being accompanied by several other Toons in their army. It would also reveal that Roger would reunite with his mom as well as his dad Bugs Bunny.^[426] It was cancelled because just as soon as Steven Spielberg saw the script, he left due to not wanting to satirize Nazism after directing Schindler's List. Eventually it was reworked into a different story (Roger would have found himself in rising stardom on Broadway and Hollywood while still searching for his mother) in and test footage was made in Lake Buena Vista, Florida which consisted of CGI, traditional animation, and live-action which didn't please Disney. A second test entirely made the Toons CGI but the film was scrapped due to budget reasons.^[427][428] Don Hahn doubts that a sequel would be made due to the rise of computer animation.^[429] In 2009, another attempt was made through ImageMovers yet the human characters will be done via Motion capture much like films including The Polar Express and Disney's A Christmas Carol while the Toons would still remain in traditional animation.^[430] It was cancelled eventually due to Bob Hoskins' retirement from acting in 2012 and later his eventual death,^[431] the unsatisfactory performance of A Christmas Carol,^[432] and the failure of Mars Needs Moms which led to projects like the Roger Rabbit sequel, Calling All Robots,^[433] a remake of Yellow Submarine,^[434] and The Nutcracker^[435] to be cancelled. Later, Zemeckis said that a sequel could still be possible without Hoskins.^[436] In 2013, it was announced that an animated Disney buddy comedy film starring Mickey Mouse and Roger called The Stooge which would have been based on the 1952 film of the same name and would have been a prequel.^[437] In 2016, Zemeckis said that the sequel moves the story of Roger and Jessica into the next few years thus moving on from film noir to the world of the 1950s. It would also feature a "digital Bob Hoskins" due to Eddie being depicted as a ghost in the film. While hand drawn is still going to be used in the film, the chances of Disney green-lighting the film are "slim".^[438] In 2018, Zemeckis claims that Disney is unlikely to ever make the sequel.^[439]

Production for Detox began in 2000, but has been delayed several times as Dr. Dre wanted to concentrate on producing for artists that were on his Aftermath record label. Work for the upcoming album dates back to 2001,^[459] where its first version was called "the most advanced rap album ever," by co-producer Scott Storch.^[460] Even at the beginning of Detox's production, it was announced that it would be Dr. Dre's final studio album,^[460] which had been confirmed at different points throughout the album's 10-year production process.^[461] Because Dr. Dre had stated he was tired of rapping about marijuana use and a stereotypical gangster lifestyle, he planned to make Detox a hip-hop musical telling the story of a professional hitman and his family, with an intended summer 2003 release date.^[459] Initially announced in 2000 after the release of Dr. Dre's previous album 2001 (1999), Detox went through many iterations during its 11-year production period, failing to have a confirmed release date due to Dr. Dre believing the project "wasn't good enough". However, the album spawned two official singles, "Kush" and "I Need a Doctor". In January 2004, Storch listed guest appearances such as 50 Cent, Eminem, Game, and Snoop Dogg. Keri Hilson told Rap-Up that she had recorded material for the album but was unsure if the tracks would make the final cut.^[462] J.

In September 2018, during Chance the Rapper's Open Mike event in Chicago, West made a surprise appearance and announced that he was working on a collaborative studio album with Chance titled Good-Ass Job.^[467] Although, after the critical and commercial failure of Chance's debut studio album The Big Day, the collaborative project has seemingly been cancelled as no news has come out since and Chance's relationship with West significantly soured during the recording of Donda, West's tenth studio album.^[468]

Gabriel repeatedly gave vague updates on the album's production over the following years, first stating in 2008 that he was "shifting focus" towards both i/o and his cover album Scratch My Back (which saw release in 2010) before later claiming in 2011 that i/o was still just a number of unfinished "song ideas" that he had yet to elaborate upon.^[472] Gabriel would continue to post about the album's production during the remainder of the 2010s, ultimately stating on BBC Radio in April 2019 that he was planning on finishing songwriting for i/o by the end of the year. Despite his plans to "get a record out" by early 2020, the album was delayed further as a result of lockdowns imposed in the wake of the COVID-19 pandemic. In an interview with Uncut magazine for their September 2020 issue, Gabriel stated that despite the delays, "I have enough songs to make a record I'm proud of,"^[473] and that a complete album could be expected at an indeterminate point in the future. The album's lead single, "Panopticom", was eventually released on January 6, 2023, with additional singles coming out each successive full moon that year.^[474] The full album was released on December 1, 2023, 28 years and eight months after production began and nearly two decades after its originally announced release date. i/o received notoriety for its repeated delays, with Rolling Stone calling it the "Chinese Democracy of Peter Gabriel albums",^[475] and Stereogum calling it "the Smile (or perhaps the Chinese Democracy) of art-rock."^[476]
• Look Outside Your Window: An unreleased studio album recorded by four members of the American band Slipknot. The material was written and recorded concurrently with the sessions for the band's fourth studio album All Hope Is Gone (2008).

The album was scheduled for release during the latter half of the band's We Are Not Your Kind touring cycle, which was postponed due to the COVID-19 pandemic. After a few years of uncertainty, on January 2, 2023, percussionist Shawn Crahan spoke about the possibility of the album being released later this year.^[477]
• The Smile Sessions: Archival recordings of the Beach Boys' unfinished album Smile took nearly 45 years to compile for a dedicated release. Numerous complications contributed to its excessively protracted delay, including bandleader Brian Wilson's irrational fear of the album. Brother and bandmate Carl Wilson compared the album's structuring to editing a film, as compiler Alan Boyd explains, "I think he was right about that. The kind of editing that the project required seemed more like the process of putting a film together than a pop record."^[478]
• Starship: A studio album by Italian electronic band Eiffel 65, this would be their fourth album since 2003, and the first one after ending their "Bloom 06 project" in 2010.

On December 26, 2010, Jari stated that three songs are finished and ready for mixing, and that four songs have "bits and pieces" missing, including vocals.^[496] On March 19, 2011, Jari announced via the Winter Madness message board that mixing had been put on hold until late summer at the earliest due to various complications, ranging from a lack of 64-bit DAW plugins to noisy nearby construction.^[497] Time was eventually announced to be split into two halves and released separately, with the titles of Time I and Time II. Time I was released on October 19, 2012 in Europe and October 22, 2012 in North America.^[498][499] Since then, production of Time II was marred with years-long delays for a multitude of reasons, until 12 January 2024, when Wintersun announced on its social media that Time II is "100%" complete.^[500] Three days later, on 15 January 2024, the band announced that "the album release will happen in the late summer of 2024, the latest early fall" and a second crowdfunding campaign was also announced.^[501] On 9 February, the band revealed the track list and cover art for Time II.^[502] On 26 February, the band announced Time II would be released on 30 August.^[503]

However, the third album has been delayed indefinitely from its original 2017 release window, and its fate remains uncertain as C418 officially resigned from working on Minecraft in late 2021; the game's version 1.13 update in 2018 contains the only new music that's been contributed to the game itself by C418 since the release of Volume Beta.^[513] In a 2021 interview, when asked about the album, he said he "considered it finished" but things had become complicated with Minecraft, so he was unsure if it would ever release.^[514]

After the release of their debut Since I Left You, the group toured for three years and collaborated with various musicians, such as Luke Steele in 2003. The first song made after the debut was Saturday Night Inside Out. These sessions would produce early versions of songs which made the final cut, such as Colours. During this time, member Robbie Chater was ill for three years with two autoimmune diseases,^[515][516] leaving him unable to produce music and further delaying the project. The group attempted several projects, including collaborations with Ariel Pink,^[517] Jennifer Herrema, and Danny Brown^[518] (the origin of Frankie Sinatra), and a psychedelic hip-hop animated feature film of Yellow Submarine^[519] (the origin of The Noisy Eater).

The video game rights for the Alien franchise were sold in December 2006 to Sega.^[521] Gearbox Software subsequently announced that it would take over development of Colonial Marines, intending it to be a direct follow-up to Aliens.^[522] The game would spend another 7 years in development, during which Gearbox's resources were also being consumed by other projects, such as Duke Nukem Forever, as well as its own franchise Borderlands, resulting in much of the game's development being outsourced to other studios. The game was released in 2013, where it was criticized for having various bugs and gameplay issues, low-quality graphics, as well as a lack of consistent continuity with the Alien film franchise. Further controversy emerged when it was found that Gearbox and Sega had presented demos of the game at conventions that had a noticeably higher graphics quality than the final product.^{[523][524][525][526][527]}
• Clockwork Aquario: The game begain development in 1993 as a Sega arcade game, but was initially cancelled in 1994 due to poor response from arcade goers due to the increasing popularity of both 3D games and fighting games.

• Duke Nukem Forever: The sequel to the 1996 game Duke Nukem 3D, Duke Nukem Forever, was in development hell for 14 years: from 1997^[539] to its release date in 2011, earning it the nickname “Duke Nukem Fornever”. The long development time was caused by numerous factors, including a switch from the Quake II engine to the Unreal Engine,^[539] having a relatively small development staff by modern standards, conflicts between 3D Realms and its publisher, Take-Two Interactive, over how it had been handling the constant delays (3D Realms' co-owners George Broussard and Scott Miller infamously maintained that the game would be released "when it's done"), and the eventual bankruptcy of 3D Realms.^{[540][541][542]} In 2009, the rights to the Duke Nukem franchise were sold to Gearbox Software, who eventually completed the game and released it in 2011.^{[543][544][545][546]} The game was ultimately a critical disappointment, with most of the criticism directed towards the game's clunky controls, long loading times, offensive humor, and overall aged and dated design.^{[547][548][549]} The game eventually proved to be profitable, according to a statement by Take-Two during its earnings call in August 2011.^[550]

Additional story content was released post-launch in the form of episodic DLC.^{[559][560][561]}
• Half-Life 2: Episode Three: In May 2006, Valve Corporation announced a trilogy of episodic games that would continue the story of Half-Life 2 (2004).^[562] Valve president Gabe Newell said the approach would allow Valve to release products more quickly after the six-year Half-Life 2 development, and that he considered the trilogy the equivalent of Half-Life 3.^[563] Episode One was released on June 1, 2006, followed by Episode Two on October 10, 2007.^[564][565] Episode Three was initially planned to be released on Christmas 2007.^[562] Concept art surfaced in 2008,^[566] and reports surfaced that Valve was working with sign language on a deaf character.^{[567][568][569]} Valve released little information regarding Episode Three in the following years; though Valve still discussed Half-Life, there was no clarity on whether further games were coming.^[570] In March 2010, Newell spoke of "broadening the emotional palette" of the series, and said that the next Half-Life game may return to "genuinely scaring the player".^[571] In 2011 he said: "We went through the episodes phase, and now we're going towards shorter and even shorter cycles ... For me, 'entertainment as a service' is a clear distillation of the episodic content model."^[572] That year, Wired described Episode Three as vaporware.^[573] Valve eventually abandoned episodic development.^[574]In 2015, Episode 3 was cancelled due to internal conflict with management over at Valve.^{[citation needed]}
• Kirby's Return to Dream Land: Development began in 2000 immediately following the release of Kirby 64: The Crystal Shards, but the game was not revealed to the public until E3 2005, alongside two other game demos which were both eventually cancelled. Due to development issues, as well as being developed late in the GameCube’s lifespan, the project would not officially be shown again until E3 2011, and the game would finally see a release later that year on its successor, the Wii. Some concepts that were scrapped would eventually be revisited in Kirby Star Allies and Kirby and the Forgotten Land, which were released for the Nintendo Switch in 2018 and 2022, respectively.
• Metroid Dread: Metroid Dread was intended to be a sequel to Metroid Fusion (2002) by Yoshio Sakamoto but was initially stopped by hardware limitations.^[575] The first attempt was made in 2005 for the Nintendo DS^[576] and first appeared in a 2005 Nintendo internal software list for "key DS games to be announced in the future";^[577] however, by late 2005, many rumours were circulating that the game was in development hell due to the DS's hardware limitations.^[578] The second attempt at the game was a playable prototype shown in E3 2009^[579] behind closed doors. The prototype didn't meet Sakamoto's expectations however, so production was halted in 2010.^[580] Despite denying Dread's existence since 2010,^[581][582] Nintendo announced that MercurySteam were developing the revived Metroid Dread for the Nintendo Switch with a release date of October 8, 2021.^[583]
• Mewgenics: First announced in 2012 by Team Meat, the game was intended to be the company's follow-up project to the highly successful Super Meat Boy. Originally set for a 2014 release, the game suffered from feature creep and differences in priorities between Team Meat's owners, Edmund McMillen and Tommy Refenes.^[584][585] The game was initially shelved in 2014, but after two years of no development, was cancelled in 2016.^[586] After leaving Team Meat, McMillen acquired the rights to Mewgenics in 2018 and rebooted its production with Tyler Glaiel and new gameplay.^[587] It is tentatively set to be released in 2025, over twelve years after its announcement.^[588]

The game was initially intended to be released on the Super Famicom like its predecessor, starting development shortly after the latter's release,^[589] before shifting focus to the Nintendo 64's Disk Drive add-on. Following the failure of the add-on, the media format of the game was shifted to a standard N64 cartridge^[590] before the development team's inexperience with 3D-oriented video game creation and a large series of delays led to the game being quietly cancelled in 2000. Eventually, assets from the cancelled project were collected and converted to a 2D format, and the project restarted development on the Game Boy Advance. Twelve years after its conception, Mother 3 was finally released on the Game Boy Advance in 2006, but only in Japan.^[590]
• Six Days in Fallujah: The game was originally scheduled for a release in 2010, but development was soon halted due to the insolvency of the developer studio Atomic Games.

• Star Citizen: Development of the game began in 2011, and is being mostly financed from a large crowdfunding campaign. The game was originally planned for a 2014 release, but significant delays in production and expansion of gameplay features meant it had to be delayed indefinitely. Due to mismanagement, some of the early work done for the first-person-shooter module has been scrapped altogether,^[591] resulting in wasted financial resources and development time. As of 2023, there is no clear release date for the game.
• StarCraft: Ghost: StarCraft: Ghost was set to be the first game in a sub-series of games set in the StarCraft universe in the genre of third-person shooters unlike the usual real-time strategy of the series.^[592] First announced in September 2002, Blizzard confirmed that the game would be worked on in conjunction with Nihilistic Software for multiple consoles and that the game was aimed for a late 2003 release date however, the game got continuous delays throughout the following months and in 2003, Nihilistic said they were discontinuing their work on the project.^[593] Soon after this, Blizzard began collaborating with Swingin' Ape Studios for a September 2005 release date but after the GameCube version was cancelled and the other two console versions were delayed to a year later, Blizzard announced an indefinite postponement of the game in order to explore possibilities of seventh generation video game consoles.

• The Elder Scrolls VI: The long-awaited sequel to the 2011 hit, The Elder Scrolls V: Skyrim, was announced at E3 2018, however it only began active development after the launch of Starfield in 2023. Being delayed significantly from its originally planned launch in 2024 according to leaked documents, producer Todd Howard said in 2021 that the game would come "some fifteen to seventeen years after Skyrim" (2026 to 2028), and Microsoft Gaming CEO Phil Spencer estimated in 2023 that the game's release was still "five plus years away" (indicating a launch of 2028 or later), suggesting further delays. This would possibly make TES6 a game shipping on a 10th generation console, quite a big jump from its predecessor, Skyrim, that originally launched on 7th generation consoles. ^{[citation needed]}
• Too Human: Announced by the developer Silicon Knights in 1999 to be released on the PlayStation,^[599] the game would feature a futuristic take on Norse mythology, as well as an ambitious class system and online multiplayer.
