I wouldn't mind seeing Jon Hamm as Bruce/Bats.
Obviously he has the right look for a Batman set in the forties or fifties, but I'm sure he'd be pretty keen to start working in the present decade for a change. He can actually time travel you know, it's the method Christian Bale used for the last Terminator abortion. Anyway I digress.
Jon Hamm as Batman
Edward Norton as The Riddler
and I don't know, somebody old and british for Alfred.
Who will survive? And what will be left of them?
