Batman and Superman are very different characters but they're both iconic and elemental. Finding the right story for them both is the key.

You never quite know what you're going to come back to and figure out how to make it work. You never quite know where that desire to finish something, or return to something in a fresh way, is going to come from. Every time I finished a film and went back and looked at it, I had changed as a person.

Particularly, the actors, to have analyzed the script in great detail from the point of view of their specific character. So that they have a handle on exactly where the character is in the chronology of things. In that sense the actors become your best check on the logic of the piece, and the way in which it all fits together. They become essential collaborators. The main thing is you have to work with very smart actors.

A hero can be anyone. Even a man doing something as simple and reassuring as putting a coat around a young boy's shoulders to let him know that the world hadn't ended.

I remember the initial genesis quite clearly. My interest in dreams comes from this notion of realizing that when you dream you create the world that you are perceiving, and I thought that feedback loop was pretty amazing.

Yeah, it's odd when you look back at your own work. Some filmmakers don't look back at their work at all. I look at my work a lot, actually. I feel like I learned something while looking at stuff I've done in terms of what I'm going to do in the future, mistakes I've made and things at work or what have you.

I'm taking a bit of a wait-and-see attitude towards 3D.
