In 2017, after Peter Browngardt finished Uncle Grandpa for Cartoon Network, he met with Audrey Diehl, the creative executive at Warner Bros., at a lunch meeting. They discussed a project in which he was not interested, and as they wrapped up lunch, Pete said, "You know, what I really want to do is to direct a Looney Tunes short". She was surprised that he was a fan of Looney Tunes and booked him a meeting with studio president, Sam Register. Browngardt expressed that he wanted to direct it in the spirit of the classic 1940s cartoons. He then began casting, hiring Eric Bauza, and as an admirer of Jim Soper's art on Instagram, hired him as a character designer.[5]
Warner Bros. Animation announced a new series in June 2018, to "consist of 1,000 minutes spread across 1–6 minute shorts each season", be released in 2019 and featuring "the brand's marquee characters voiced by their current voice actors in simple gag-driven and visually vibrant stories". The style of the series is reminiscent of the classic Looney Tunes shorts, primarily those by Tex Avery, Bob Clampett, and Arthur Davis. Register and Browngardt serve as executive producers for the series.[2][6] The characters are designed by Jim Soper, with the model sheets copyright dating back to 2018.[7][8][9] The initial designs for Looney Tunes Cartoons were previewed in the Warner Bros. Animation logo that was first shown before Teen Titans Go! To the Movies and in subsequent WB direct-to-video movies, the logo featuring Daffy Duck and Porky Pig and itself directed and storyboarded by Browngardt and animated by animation veteran Eric Goldberg.[10] The animation of the series was directed by Joey Capps, who also did animation work on Adult Swim's Superjail!.

Producers included copious amounts of cartoon violence and Acme Corporation weaponry, but excluded any depictions of firearms in the first season; Elmer Fudd, for example, used different non-firearm weapons (e.i. a scythe or an axe) to hunt Bugs Bunny instead of his shotgun.[14][15] With the release of Space Jam: A New Legacy, the restriction was removed.[16]

The first ten shorts debuted at the Annecy International Animated Film Festival in June 2019, and were met with very positive reactions, being described as true to the spirit of the original Looney Tunes shorts. Film reviewing site Oneofus.net noted: "While only time will tell if these shorts will become classics, they decidedly will be seen as a noble attempt to bring the "Looney" back into Looney Tunes. The cartoons are manic, beautifully animated, and feature amazing voice acting. Even the music tries to recapture the spirit of the originals. Even the characters are doing like what they did in old 30s and 40s shorts".[11]
The official launch of the first ten episodes with HBO Max was also met with positive reviews. Review aggregator Rotten Tomatoes reported an approval rating of 88% based on 25 reviews, with an average rating of 8.00/10.
