It's very important that a film that intends to play tricks on the audience... has to play fair with the audience. For me, any time you're going to have a reveal in the film, it's essential that it have been shown to the audience as much as possible. What that means is that some people are going to figure it out very early on. Other people not til the end. Everybody watches the film differently.

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

I think there's a vague sense out there that movies are becoming more and more unreal. I know I've felt it.

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 thing you fail to grasp is that people are not basically good. We are basically selfish. We shove and clamour and cry for adoration, and beat down everyone else to get it. Life is a competition of prattling peacocks enraptured in inane mating rituals. But for all our effacing and self-importance, we are all slaves to what we fear most. You have so very much to learn. Here. Let me teach you.

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.

One of the things you do as a writer and as a filmmaker is grasp for resonant symbols and imagery without necessarily fully understanding it yourself.
