I'm reluctant and kind of torn. I mean, I'm not sure if he could pull it off. We've never really seen him do crazy before, have we? I have no sense of whether or not he'd be any good.
But I do trust Christopher Nolan. A lot. So maybe he'll be the next Katie Holmes (not bad, per se, just not quite up to par) or maybe he'll be better than Jack Nicholson (but not Mark Hamill, 'cause I doubt he can be that good).
