Director Zack Snyder officially announced that Batman will indeed appear in his follow-up to “Man of Steel.” He said in a statement, “I'm so excited to begin working again with Henry Cavill in the world we created, and I can't wait to expand the DC Universe in this next chapter. Let’s face it, it's beyond mythological to have Superman and our new Batman facing off, since they are the greatest Super Heroes in the world.”
At the panel a logo for the movie was revealed that combines Superman's “S” shield (yes, we know it's not an “S”) with the Bat-symbol, which notably looked different than the one in Christopher Nolan's trilogy. In addition to Henry Cavill, Amy Adams, Laurence Fishburne and Diane Lane will return, but Batman has yet to be cast.
Unlike Marvel's Avengers, the 2015 film will feature Batman and Superman as rivals, fighting each other in a story based off Frank Miller's graphic novel “The Dark Knight Returns.” In fact, a quote from the work—Batman's “I want you to remember my hand at your throat. I want you to remember the one man who beat you”—was used in the Comic-Con presentation.
It's assumed, though, that the two superheroes will wind up best of bros at a certain point. DC plans on releasing a Justice League film in 2017.
