For me, as a film goer, I like nothing more than to sit in the cinema, have the lights go down and not know what I'm about to see or unfold on-screen. Every time we go to make a film, we do everything we can to try to systematise things so we're able to make the film in private, so that when it's finished it's up to the audience to make of it what they will.

I don't ever like to feel myself in the position to demand of an actor that they trust I'm going to do something worthwhile. I feel a responsibility to articulate what it is I'm going to do. Whether that's showing them a full script or sitting down with them and describing my ideas in detail. It's a very healthy burden on me as a film director to be able to articulate what I want to do, to inspire actors, rather than just saying, take it on trust I'll be able to do something worthwhile.

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.

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.

Films are subjective - what you like, what you don't like. But the thing for me that is absolutely unifying is the idea that every time I go to the cinema and pay my money and sit down and watch a film go up on-screen, I want to feel that the people who made that film think it's the best movie in the world, that they poured everything into it and they really love it. Whether or not I agree with what they've done, I want that effort there - I want that sincerity. And when you don't feel it, that's the only time I feel like I'm wasting my time at the movies.

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.

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.
