"I know there's been a lot of speculation about what we're doing," Snyder said. "It is official that we're going to make another Superman movie." He went on to say "there's one particular part of the film I might be able to help you out with.
"We're not adapting this thing," Snyder said, "but it will help us tell you something."
Harry Lennix (the main General from Man of Steel) read some very familiar lines:
"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."
Yes, that's from The Dark Knight Returns. And yes, the Man of Steel sequel is going to be Superman/Batman.
It looks like WB's finally found a way to start building their way toward Justice League, just like Marvel built toward The Avengers. No actor has been announced for Batman yet, so let the speculations commence!
