I foresee that role being filled by some kinda American Dad type dude, ya know, the Jay Leno chin thingy. That might be too goofy tho.

But who knows. If you would have asked me if Robert Downey Jr. could pull off a superhero role before Iron Man, I woulda told you to take a flying leap. I can't imagine anyone else playing it and doing 1/2 as good a job now.
