I'm still adjusting to the awesomeness that was Man of Steel, but while I was over in Melbourne for PAX Australia 2013, I read that the director of Man of Steel, Zack Snyder, confirmed a Superman/Batman movie for 2015.
At the end of the DC panel at Comic-Con 2013, Zack Snyder tool the stage, gesturing that moderator Chris Hardwick should move out of the way where he said "I'm gonna take the lectern from you, because some sh*t's going to happen up here. It's official that we are going to make another Superman movie. And you say, Zack, what is the movie about? But you don't want me to tell you that. You want to go and see the movie. But I can say that maybe there's a single element that will be in the film that I could... help you out with. I was thinking about how to do that. I pored through the DC Universe to look for a way to tell this thing. We're writing the thing now, but I came across a thing I found that'll help you understand it."
While this is exciting news, it doesn't confirm a sequel to Man of Steel, which is weird. Harry Lennix, who starred in Man of Steel, read a line from Frank Miller's The Dark Knight Returns: "I want you to remember, Clark, in all the years to come, in all your most private moments, I want you to remember my hand at your throat. I want you to remember the one man who beat you."
This was Batman speaking to Superman at the end of Miller's story, which had the crowd going absolutely wild at Hall H at Comic-Con 2013. There's not many details on the movie itself, but we should expect a fight between Superman and Batman, but Superman receiving the bad end of the stick in the fight. I'm hoping we see the rebooted Batman in Man of Steel II, with Batman - for whatever reason - kicking Kal-El's ass for whatever reason.
