Actually, I can't stand watching violent scenes in films; I avoid watching horror films. I don't tend to watch action films mainly because I find them boring, but I watch the films of David Cronenberg and Martin Scorsese, usually in a state close to having a heart attack. I'm a complete coward. I make violent films as a result of my sensitivity to violence - in other words, my fear of violence.
In my opinion, all relationships between people have some sort of violence, and it is central.
