Well, you always discover a lot in the editing room. Particularly the action, because you have to over-shoot a lot and shoot an enormous amount of material because many of the sequences have to be discovered in the editing and manipulation of it.

I've always believed that if you want to really try and make a great film, not a good film, but a great film, you have to take a lot of risks.

Films are subjective - what you like, what you don't like. But the thing for me that is absolutely unifying is the idea that every time I go to the cinema and pay my money and sit down and watch a film go up on-screen, I want to feel that the people who made that film think it's the best movie in the world, that they poured everything into it and they really love it. Whether or not I agree with what they've done, I want that effort there - I want that sincerity. And when you don't feel it, that's the only time I feel like I'm wasting my time at the movies.

I have to believe that when my eyes are closed, the world's still there. (Leonard Shelby, Memento)

I believe movies are one of the great American art forms and the shared experience of watching a story unfold on screen is an important and joyful pastime. The movie theatre is my home, and the idea that someone would violate that innocent and hopeful place in such an unbearably savage way is devastating to me.

The problem with big films is they snowball very rapidly and you can never pull back. It's a pipeline that needs to be fed.

For me, Batman is the one that can most clearly be taken seriously. He's not from another planet, or filled with radioactive gunk. I mean, Superman is essentially a god, but Batman is more like Hercules: he's a human being, very flawed, and bridges the divide.
