Lots of BvS details from the Empire mag.
"We are playing him 45 or 46," director Zack Snyder confirms. "He has been Batman for 20 years. All the history is there. Was there a Robin at one time? Possibly. He has lost those near and dear to him, and not necessarily from old age of disease.. We want to assume that Batman has reached this point in his life and career as a superhero, and Superman represents a sort of philiophical change. He is a paradigm shift for Batman: 'I've been fighting criminals all my life, trying to find justice, and now I am confronted with a concept that is transcendent to me.' In the face of Superman, a man robbing a bank doesn't matter.."
"Initially I thought, 'I'm older, it doesn't seem like the right sort of fit for me,'" adds star Ben Affleck. "Then Zack pitched me his concept for this older, more broken, kind of f**ked up Batman. It was something we haven't seen. We have seen that Batman is willing to cross the line to protect people. That vigilantism has been a part of his character all along, and we are tapping into that mentality when faced by something as potentially as deadly a Superman."
"He's having a crisis of conscience. 'Am I really just a vigilante who stalks the alleys of Gotham?'" asks Snyder. "It is rich stuff that he deals with. Ben does an amazing job." Early on in their feature, the director indicates that Batman is in some ways the villain of this movie, but later clarifies that by stating that who fans side with when the heroes meet in battle will ultimately come down to their own perceptions. "It's a point of view thing. That is why Dawn of Justice is the full title. What it does is allow us to start this conversation." Don't go thinking that the Dark Knight isn't a hero though. The magazine reveals that Batman does indeed have history with The Joker and Harley Quinn, and indeed all of the criminals in Belle Reve who will ultimately make up Task Force X in Suicide Squad. Batman is responsible for putting them all in there.
"What we are doing is ground up all the way. It is one giant story," director Zack Snyder explains. "The first thing we had was the Justice League concept. The other movies, in a way, have to support that. That is our Wonder Woman, our Aquaman. They have their own creative concepts that supports them, but they do serve Justice League in the coming together of those heroes. I want all the other directors of the other films to be able to stretch their legs and do what they want, but at the same time there is a big interconnected universe. I have given everyone amazing access to our story, to me, and what we are doing. All the films have like minded conceptual jumping on points. "
Snyder wasn't willing to get into specifics, but he did tease what the magazine describes as an "elusive" cameo for Aquaman in Dawn of Justice by promising only that, "You will understand he exists."
the magazine was lucky enough to see a board which maps out how and where the movies take place in the DC Extended Universe and how they all link up to wach other. Producer Deborah Snyder describes that as, "Kind of a timeline of what every movie is, where it is going, and where the films fit in relation to each other."
Fellow producer Charles Roven meanwhile went into even further details about how they're ensuring that these movies all exist in the same world while not restricting their directors and writers too much. "We call it the sandbox. It has borders around it, but everybody gets to play in the sandbox. On Suicide Squad, David Ayer has a lot of specific control over his area of the sandbox. Even if he crosses the line a little bit, we see if we can push our boundaries back a little bit."
