If Warner Brothers wants any continuity to their DC universe that they've created, and if they want to be true to the source material that Zack Synder claims the Man of Steel sequel will be based (The Dark Knight Returns graphic novel), then it would make sense that Batman would be the older, even more crazy vigilante who fights crime now with an AK-47 and a heating pad for his back. With that said, then of course they should cast an older actor. BatmanOnFilm says that's the case and these are the rumored names to take over the role.
BatmanOnFilm has been working around the clock to get more details on this movie. And according to that site’s sources (stating it’s more than one and less than ten unnamed people), an older actor will be targeted to play the Dark Knight. So it means that Joseph Gordon-Levitt is definitely out if this rumor is true. And the site stated a few names, including Josh Duhamel, Jude Law, Gerard Butler, Josh Brolin, Jon Hamm, Brad Pitt, Ben Affleck and Jim Caviezel.
Whoa, Jon Hamm as Batman? A millions vaginas just screamed out then fell silent because the women they were attached to just slid off their chairs.
