I work with my dreams or nightmares.

The way a child discovers the world constantly replicates the way science began. You start to notice what's around you, and you get very curious about how things work. How things interrelate. It's as simple as seeing a bug that intrigues you. You want to know where it goes at night; who its friends are; what it eats.

All stereotypes turn out to be true. This is a horrifying thing about life. All those things you fought against as a youth: you begin to realize they're stereotypes because they're true.

Anybody who comes to the cinema is bringing they're whole sexual history, their literary history, their movie literacy, their culture, their language, their religion, whatever they've got. I can't possibly manipulate all of that, nor do I want to.

It was apparent to me that religion was an invented thing, a wish-fulfillment thing, a fantasy thing. It was much more real, dangerous, to accept that mortality was the end for you as an individual. As an atheist, I don't believe in an afterlife, so if you're thinking of murder, if your subject is murder, then that's a physical act of absolute destruction because you're ending something, a body, that is unique. That person never existed before, will never exist again, will not be karmically recycled, will not go to heaven, therefore I take it seriously.

Let's put it this way, when I was casting, I cast Viggo first and then found someone who could play his wife, rather than the other way around. So for me he's still the lead character.

Each kid has a different level of expertise and some of them are very raw and inexperienced and some are incredibly mature and experienced. So you just have to go with what they are rather than have some abstract technique that you're going to try to apply to them.
