Film Fact #1:
Michael J. Fox wasn’t the first actor to play Marty McFly in Back to the Future.
Much of the movie was filmed with Eric Stoltz (Mask 1985).
He was let go five weeks into filming because he lacked “the precise comedic sense” the director was after. Michael J. Fox was hired and the film was re-shot.
Michael J. Fox was always first choice for the character but originally his filming schedule of the TV show Family Ties wouldn’t allow for his availability.
Luckily a deal was eventually made and he became the lovable time traveller we’re all so familiar with.
