"Bruce Wayne in my mind came from privilege and I think that's why he's more dour and angry. He's self-made as far as his becoming all of these cool things we like him for... Dick Grayson didn't come from that. Dick Grayson came from a circus family. Essentially people who aren't rich and they are self-made. They're entertainers. They're gymnasts. They're people who live hand-to-mouth and that's something that informs him and his attitude... he's a fascinating guy to me, because he had all the same things happen to him. He's got some of the same negatives as Bruce Wayne and then from a society standpoint -- obviously he was adopted into Bruce Wayne's life... but he didn't start that way. He's this guy who has all these negatives and then even more negatives and yet he remains... Those are things why I like Dick Grayson, why I like the idea of Nightwing as a movie."
