Back to the Future was a 1985 hit film in the adventure, science fiction and fantasy genres. It starred Michael J. Fox and Christopher Lloyd.
While purists may argue over whether its light comedic script about a misfit boy befriended by a mad scientist who travels back in time was true sci-fi, moviegoers had no problems with it, Back to the Future became the highest-grossing film of the year and spawned two sequels.
Lloyd and Fox, both well-established actors, Lloyd from independent film, smaller budget movies and the stage, and Fox in the popular American situation comedy Family Ties, became superstars.
