Crispin Glover – Back to the Future Part II
Glover didn’t agree to return because of some apparent “moral” objections. Instead, the production hired an actor to impersonate him and put him in prosthetics. That, combined with some footage from the first film, made it seem like Glover had reprised his role of George McFly. He was not psyched about this development.
Some of them, sure, but there are some very beloved movies on that list.
