When writing the script for "Part II", Gale wanted to push the first film's ideas further for humorous effect. Zemeckis said he was somewhat concerned about portraying the future because of the risk of making wildly inaccurate predictions. According to Gale, they tried to make the future a nice place, "where what's wrong is due to who lives in the future as opposed to the technology" in contrast to the pessimistic, Orwellian future seen in most science fiction. To keep production costs low and take advantage of an extended break Fox had from "Family Ties" (which was ending its run when filming began), it was shot back-to-back with sequel "Part III".
