I've had pretty much the same crew for all the films that I've made, and I've managed to have really nice, calm, funny people. That is a big part of it, a family feeling of warmth and finding something interesting and making a platform for them to perform. It's a very difficult job, acting, in that it's totally counterintuitive to how we are brought up.

If an actor commits properly to a role, they do a bit mad during a shoot. If they're going to do that, they should balance themselves by doing a role as a yoga teacher.

Sometimes my scripts get so dissolved, and they're so different from when I wrote them originally, that I find it hard to find what I wrote in it.

Doctor Who is pretty dark, I think. Generally its dark; its always been dark.

I tend to shoot really quick so you don't get the problems you might get on a traditional film where you shoot one way, then another, and it's pissing down with rain and they won't cut together. We shoot so fast we can incorporate the weather into it. The worst weather we had was when they were in the caravan up the mountain and there was no cover. One man's weather is another man's production value. To create the sleet would cost a fortune but we got it for free so we'll just have to go with it.

The things that inspire people to think are what keeps a film alive.

If I'd been offered 'Spider-Man,' I probably would have done it. I don't think it's bad to go and do those things.
