When we talk about violence, we're talking about the destruction of the human body, and I don't lose sight of that. In general, my filmmaking is fairly body-oriented, because what you're photographing is people, bodies.
I don't think that the flesh is necessarily treacherous, evil, bad. It is cantankerous, and it is independent. The idea of independence is the key. It really is like colonialism. The colonies suddenly decide that they can and should exist with their own personality and should detach from the control of the mother country. At first the colony is perceived as being treacherous. It's a betrayal. Ultimately, it can be seen as the separation of a partner that could be very valuable as an equal rather than as something you dominate.
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.
You need language for thought, and you need language to anticipate death. There is no abstract thought without language and no anticipation. I think the anticipation of death without language would be impossible.
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.
