What would be a great career comeback role for him?
Maybe something based on a serious fiction book? If Bud Not Buddy was ever made into a movie he should audition. Or if the book Heaven is adapted for the screen he'd be great as the dad or the uncle (they were twins I think so he could even play both of them) He can act so I think he'd be great in a serious dramatic role again (both books also have a little humor and he could definitely do the funny and the serious parts) even though he's been doing some lousy movies lately.
Any other thoughts on what you think would be a good career jump restart role for him?
