So what new physical challenges did you face for The Dark Knight?
We’ve gone a bit further with Keysi, the martial art we learned for the first one.
I’m actually learning how to do it more realistically than ever before, though it’s such an extremely violent way of fighting; there are literally moves where you tear someone’s cheek away from their face, or rip their nose off – every part of you becomes a weapon. It’s formidable.
Batman doesn’t kill, so we can’t have him doing that: we modify it.
