Eric Stoltz was supposed to play Marty McFly in 'Back To The Future.' He filmed the movie for five weeks before the role was handed to Michael J. Fox, who stars in all three films in the cult trilogy. Footage of Stoltz acting in the diner scene with Crispin Glover (Marty's dad George) was included in the 25th anniversary version of the movie's DVD.
