It is the sequel to the 1985 film Back to the Future and the second installment in the Back to the Future trilogy . The film stars Michael J. Fox, Christopher Lloyd, Thomas F. Wilson, and Lea Thompson . In the plot, Marty McFly (Fox) and his friend Dr. Emmett "Doc" Brown (Lloyd) travel to 2015, where bully Biff Tannen (Wilson) steals Doc's DeLorean time machine and uses it to alter history for the worse . </P> <P> The film was produced on a $40 - million budget and was filmed back to back with its sequel, Part III . Filming began in February 1989 after two years were spent building the sets and writing the scripts . Two actors from the first film, Crispin Glover and Claudia Wells, did not return . While Elisabeth Shue was recast in the role of Wells's character, Jennifer, Glover's character, George McFly, was not only minimized in the plot, but also was obscured and recreated with another actor . Glover successfully sued Zemeckis and Gale, changing how producers can deal with the departure and replacement of actors in a role . Back to the Future Part II was also a ground - breaking project for effects studio Industrial Light & Magic (ILM): In addition to digital compositing, ILM used the VistaGlide motion control camera system, which allowed an actor to portray multiple characters simultaneously on - screen without sacrificing camera movement . </P>
