Off the Cuff With Peter Travers: Crispin Glover

Peter Travers recently hosted a chat session with the elusive Crispin Glover and got the star of Tim Burton's new Alice in Wonderland to reveal the real reason he didn't star in Back to the Future Part II, why River's Edge is one of the few films he's seen featuring his own work, and the truth behind his infamous 1987 David Letterman interview. "I've always tended toward having an interest in more extreme facets of human existence," Glover says (he also explains the birth of his "Clowny Clown Clown" video). Don't miss his a cappella performance of "Ben" and rare honest look back at his best roles in Off the Cuff.
