What I try to do is write from the inside out. I really try to jump into the world of the film and the characters, try to imagine myself in that world rather than imagining it as a film I'm watching onscreen. Sometimes, that means I'm discovering things the way the audience will, with character and story.

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.

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 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.

What I love about IMAX is with its extraordinary resolution and color reproduction it's a very rich image with incredible detail. It lends itself wonderfully to huge shots with much in the frame. Thousands of extras and all the rest.

People want to see something that shows them you can do what you say. That's the trick.

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