Henry Cavill will reprise his role as Superman, but it is unclear who will play Batman in the new film. A release date of 2015 has been set, with tentative plans for a Flash movie appearing in 2016 and a Justice League movie in 2017, sources said.

David Goyer, who co-wrote Man of Steel, will write the script. Rumors of the team-up movie have been circulating Comic-Con for a couple of days.

Snyder's Man of Steel, which rebooted the Superman franchise, has grossed north of $600 million worldwide since it hit theaters this June.

Batman and Superman have a long history of teaming up in the comic book universe. Starting in 1954, D.C. published a comic titled Worlds Finest, which featured the two as best pals who joined forces.

The dynamic between the two changed with Frank Miller’s 1986 The Dark Knight mini-series in which the two were on opposite sides of the philosophical and political fence.

Since then, that sort of antagonism has permeated most of the stories involving their interaction.

The Batman & Superman film is an interesting zigzag as D.C. builds toward a Justice League movie. Most expected D.C. to work toward its team movie with films featuring individual heroes, the way Marvel has done, or the opposite: one big movie leading to individual outings.
