When you start really thinking about the potential of the human mind and its ability to create an entire world while you're sleeping, I come away feeling like our minds are not remotely understood by science.

I have been interested in dreams, really since I was a kid. I have always been fascinated by the idea that your mind, when you are asleep, can create a world in a dream and you are perceiving it as though it really existed.

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.

To me, any kind of filmmaking that's reactive is not going to be as good as something more inventive and original.

By the time I was 10 or 11, I knew I wanted to make films.

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.
