The term 'genre' eventually becomes pejorative because you're referring to something that's so codified and ritualised that it ceases to have the power and meaning it had when it first started.

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.

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

Superheroes fill a gap in the pop culture psyche, similar to the role of Greek mythology. There isn't really anything else that does the job in modern terms. For me, Batman is the one that can most clearly be taken seriously.

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.

Every film should have its own world, a logic and feel to it that expands beyond the exact image that the audience is seeing.
