Back to the Future Part II

Back to the Future Part II is a 1989 American science fiction film directed by Robert Zemeckis from a screenplay by Bob Gale; both conceived the story. It is a sequel to the 1985 film Back to the Future and the second installment in the Back to the Future franchise. The film stars Michael J. Fox, Christopher Lloyd, Lea Thompson and Thomas F. Wilson, with Elisabeth Shue (replacing Claudia Wells) and Jeffrey Weissman (replacing Crispin Glover) in supporting roles. The film follows Marty McFly (Fox) and his friend Doctor Emmett "Doc" Brown (Lloyd) as they travel from 1985 to 2015 to prevent the former's son from tarnishing their family's future. When their arch-nemesis Biff Tannen (Wilson) steals the DeLorean time machine and uses it to alter history for his benefit, the duo must return to 1955 to set things right.
