"I've always been terrified of violence which is probably why I keep making violent films - I'm trying to exorcise some demons or something. My mum ended up bringing me up on the edge of a big estate in south London, so I was on the periphery of violence - a lot of football violence and stuff because I was a Millwall supporter. So I've always had a very healthy fear of it, yet at the same time a fascination. I think in all of my films that's a really strong subtext... people who are terrified by violence but are yet compelled by it as well."
