Your'e seeing me develop, not only as a filmmaker if you've seen my earlier films, but you're seeing me kind of learn how to be a human, how my philosophy has evolved.

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.

Consciousness is the original sin: consciousness of the inevitability of our death.

Do you remember when you found out you wouldn't live forever? People don't talk about this, but everybody had to go through it because you're not born with that knowledge.

I never thought I was doing the same thing as directors like John Carpenter, George Romero, and sometimes even Hitchcock, even though I've been sometimes compared to those other guys. We're after different game.

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.
