"For this film, I had something to say about Bruce Wayne as a character, what his motivations are. That there’s something dark and wrong about what drives him. Batman is a super hero and he does good. But I think the Bruce Wayne part of the character’s motivation is slightly twisted. Bruce’s motivations don’t come from a good place. He’s angry and, in that revenge is really his goal, he’s a dishonest character. That’s why he has to wear a mask. He’s doing good, but he’s not doing all the right things for all the right reasons."
