Back to the Future
Back to the Future is a 1985 American science fiction adventure film directed by Robert Zemeckis and written by Zemeckis and Bob Gale.[1] It stars Michael J. Fox as Marty McFly, a 17-year-old high school student accidentally transported from 1985 to 1955 in a plutonium-powered DeLorean time machine invented by his eccentric friend, scientist Emmett "Doc" Brown, played by Christopher Lloyd.[2] Produced by Steven Spielberg and released by Universal Pictures on July 3, 1985, the film follows Marty's efforts to ensure his parents' romance and return to the present without altering his own existence.[3]The production faced challenges, including the replacement of Eric Stoltz, who filmed for five weeks as McFly before being dismissed for delivering a dramatic rather than comedic performance mismatched to the film's tone, with Fox stepping in despite his concurrent Family Ties commitments.[4][5] Budgeted at $19 million, it grossed over $388 million worldwide, becoming the highest-grossing film of 1985 and launching a trilogy that revitalized the time-travel genre.[6][7] Its cultural resonance endures through iconic elements like the flaming tire tracks of the DeLorean, quotable lines such as "Great Scott!", and predictions like video calls, earning preservation in the National Film Registry in 2007 for its significance to American cinema.[7][8]
