I'm sure it won't be a mega star who will be the next Bruce Wayne / Batman, but I'm kinda wondering how Hugh Jackman or Tom Cruise would look in the role. Even though Cruise is a whackjob with Scientology, he's still a great actor. John Hamm would be interesting, but not sure if he could pull off the action role. Another interesting choice would be Ryan Gossling. Bruce is an aloof character, and Ryan pulled that off well in Drive.
