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.

The problem with doing a schlocky or big budget studio film is that it wouldn't actually be fun for me. It wouldn't be exciting.

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.

The filmmaking process is a very personal one to me, I mean it really is a personal kind of communication. It's not as though its a study of fear or any of that stuff.

My dentist said to me the other day: I've enough problems in my life, so why should I see your films?

Well I don't think sex and violence have ever stopped a movie from being mainstream.

As a filmmaker, I ask questions but don't have answers. Moviemaking is a philosophical exploration. I invite the audience to come on the journey and discover what they think and feel.
