The greatest film in my collection at the moment is 'Oliver', the musical, and I watch it with my kids a lot. You can get really great ideas from kids' movies. It sounds funny that that's influencing these violent films, but in a way it's wherever your head is at the time. Like 'Chitty Chitty Bang Bang' - it's a fucking scary film, you know. I always look at the darker side of things I suppose, but you see how it's presented in the kids' films - that's the best example of the bad guy and the good guy.
Westerns are a great example of that as well.
Some get it wrong and go too far, and some of them don't go far enough. If you don't do it enough it's seen to be weak, it becomes like a 'Lock Stock', like a comic. But if you do it too much, then it's a snuff movie. If I want my kids to stop doing something I'll say 'The Child Catcher's coming to get you', and they're off. And the Big Bad Wolf.
