Eric Stoltz as Marty McFly: See the 'Back to the Future' that almost was


It's long been known that Eric Stoltz was originally cast as Marty McFly in "Back to the Future." What we haven't seen -- until now -- was actual footage from Stoltz's brief time on the film.

Now, though, a few snippets of Stoltz as Marty -- including the famous scene where he sits down next to his future father ( Crispin Glover) in a diner -- have been made public for the first time (you can see them in the clip above). They're part of the "Back to the Future" 25th anniversary Blu-ray set.
