Back to the Future Part II is a 1989 film and a sequel to the 1985 film Back to the Future. Like the previous film, it was directed by Robert Zemeckis and written by Zemeckis and Bob Gale. Part II and the third installment of the trilogy, Back to the Future Part III, were filmed back-to-back, with some of the scenes of Parts II and III filmed concurrently, and released six months apart. Although released in 1989 and 1990, both films continued to portray 1985 as the present, due to them directly following the events of the first film.
Part II follows the continued adventures of Marty McFly and "Doc" Emmett Brown as they use their time-traveling DeLorean, which is now capable of flight and no longer is run by plutonium, to travel into a retro-futuristic version of 2015, an alternate 1985 and the principal setting of the first film in 1955. The film ends with a cliffhanger that is resolved in Part III.
