Superman Homepage brings us the following:
Since Zack Snyder announced at Comic-Con last month that Batman would be joining Superman on the big screen in a follow-up movie to "Man of Steel", there's been a lot of speculation about which actor will don the cape and cowl.
With Christian Bale's time as the Dark Knight all done, Warner Bros. will look to cast another actor in the role of Batman... a Batman which will reintroduce the character in this new cinematic DC Universe.
There's been a lot of self-congratulatory back-patting going on between Batman fan sites and movie rumor sites of late, with casting rumors being touted as "news exclusives". Claims are being made that Warner Bros. are looking for a more mature actor to play an older, experienced Batman, with names like Josh Brolin and Jim Caviezel being thrown up. However the studio denies all the chatter, telling HollywoodReporter.com that the casting process hasn't even begun.
A Superman Homepage source tells us that Zack Snyder may currently be more involved with movie title possibilities and how to represent the film, with the director looking at "World's Finest" and "Public Enemies" ideas for inspiration.It would be an interesting twist to, instead of focusing on Superman and Batman facing off, having the film be based on the animated film "Superman/Batman: Public Enemies", which is another podcast.
