I think the films Insomnia and Memento share all sorts of thematic concerns, such as the relationship between motivation and action, and the difficulty of reconciling your view of the story with the supposed objective view of that story.

Memory can change the shape of a room; it can change the color of a car. And memories can be distorted. They're just an interpretation, they're not a record, and they're irrelevant if you have the facts. (Leonard Shelby, Memento)

I will miss the Batman. I like to think that he'll miss me, but he's never been particularly sentimental.

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.

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?

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.

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.
