Christian Bale will be Bruce Wayne for the foreseeable future, more than likely.
Shortly, or even currently (I don't know) he will be on the set filming as John Connor.
Two legendary franchises: Batman and Terminator. He even has a look to him where I could see him cast as James Bond, as well.
I can't remember too many actors getting two or more huge title roles like that since Harrison Ford: Han Solo (Star Wars) and Indiana Jones.
Musclemen Arnold and Sylvester have niche movies, especially Stallone with Rocky and Rambo, but they are not comparable to such industry giants as Star Wars, Jones, Batman, and Terminator.
So has Christian Bale quietly taken Harrison Ford's mantel?
I'd have nothing against him if he has. Bale's a good actor and I like his movies. American Psycho is a lot of fun for me as well.
