"When people come out with movies about characters I’ve worked on, I always hate them. I have my own ideas about what the characters are like. I mean, I can’t watch a Batman movie. I’ve seen pieces of them, but I generally think, No, that’s not him. And I walk out of the theater before it’s over."

"I’m not condemning what he (Nolan) does. I don’t even understand it, except that he seems to think he owns the title Dark Knight. [laughs] He’s about 20 years too late for that. It’s been used."

"The Dark Knight series is all from Batman’s point of view. But if you look at Dark Knight 2, you’ll see a Superman who’s much calmer than the one in the first Dark Knight. Batman and Superman are dead opposites. I love Superman. Do I love Batman more? They’re not people. They’re only lines on paper."

I bet it's a reference to Smallville when Tom Welling got confused and thought he was playing Batman, standing on top of gargoyles and wearing a black coat.
