He's playing batman.
it's confirmed.
"I'm not interested in Saturn, I said Mars."
He should steer clear of any other "superhero" role for now, especially a "masked man".
It would be horrible to be typecast at this stage in the game.
I do think though, that movie talks for that have started back up. He should run. Or play someone else, if they do try to do the movie and approach him again.
