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.

People want to see something that shows them you can do what you say. That's the trick.

The structural notions to me always have to be worked out very carefully in the script stage. Whatever a particular structure is. Whether it's chronological or non-chronological. To me that's always about what point of view are we trying to address in the film?

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 most stressful and difficult part of steering a large movie is that you are taking on the responsibility of communicating with a very wide audience. You can't ever hide behind the notion of, 'Okay, they just don't get it,' or, 'Certain people just don't get it.' You have to be mindful of the size of your audience, and you have to communicate in a way that lets them in.

What drew me to Batman in the first place was Bruce Wayne's story, and that he's a real character whose story begins in childhood. He's not a fully formed character like James Bond, so what we're doing is following the journey of this guy from a child who goes through this horrible experience of becoming this extraordinary character. That, for me, became a three-part story. And obviously the third part becomes the ending of the guy's story.

The real truth of that is that much as you want to believe that it's you being on top of everything, you're actually relying massively on the people around you.
