Back to the Future is a 1985 American science fiction film directed by Robert Zemeckis and written by Zemeckis and Bob Gale. It stars Michael J. Fox, Christopher Lloyd, Lea Thompson, Crispin Glover, and Thomas F. Wilson. Set in 1985, it follows Marty McFly (Fox), a teenager accidentally sent back to 1955 in a time-traveling DeLorean automobile built by his eccentric scientist friend Emmett "Doc" Brown (Lloyd), where he inadvertently prevents his future parents from falling in love – threatening his own existence – and is forced to reconcile them and somehow get back to the future. Gale and Zemeckis conceived the idea for Back to the Future in 1980.
