For me, the first fact of human existence is the human body. But if you embrace the reality of the human body, you embrace mortality, and that is a very difficult thing for anything to do because the self-conscious mind cannot imagine non-existence. It's impossible to do.

I have no rules. For me, it's a full, full experience to make a movie. It takes a lot of time, and I want there to be a lot of stuff in it. You're looking for every shot in the movie to have resonance and want it to be something you can see a second time, and then I'd like it to be something you can see 10 years later, and it becomes a different movie, because you're a different person. So that means I want it to be deep, not in a pretentious way, but I guess I can say I am pretentious in that I pretend. I have aspirations that the movie should trigger off a lot of complex responses.

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.

For me, it's just a normal artistic endeavour to explore the dark side. Certainly, I'm not alone in it. Artists generally don't like to accept the version of reality that society and culture hand them. They want to know what's really going on. So you're always looking in the ceilings, under the floorboards and behind the walls, trying to find the mechanisms, the structures, and the truth. I find that often leads you into some dark places.

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.

So not only can you not imagine dying, you can't really imagine existence before you were born.

For example I don't work with William Hurt the same way that I will work with Viggo. They're different guys and they work in different ways. So a good sensitive director has his general style and technique and personality that he uses but you don't impose that on the actors.
