It is being reported that Joseph Gordon-Levitt is already being primed to star as Batman in the upcoming "Justice League" film.
While the the film is far from being in production, the rumor mill is already stirring with possible ideas for the future of the Batman franchise. Some say they wouldn't be surprised if there was a possible connection between Batman and the end of the "Man of Steel" film, that would segue to the "Justice League" film. Again, these are rumors, but one could argue it would be quite the cliffhanger.
"Man of Steel" will be released on June 14, 2013 and "Justice League" is set for a 2015 release.
Countdown to the release of The Justice League, with the iPhone Movie Countdown Clock App.
