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

People say, "How do you get into the British film industry?" There is no British film industry, there are just people making films and finding their own way. It's not like in the States where there are studios and there's an actual infrastructure to it; there's just nothing here. You make it from scratch a lot of the time.

If you make a movie in the UK you've got to embrace the weather with open arms... We got some of the most amazing weather as well. It's maybe why some of these places, like the Lake District, don't get filmed in so much. If you were trying to make it look like some kind of chocolate box image of England you'd be there all year waiting for the sun to come out.

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.

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

I like that confusion when people are speaking in the same language but still can't understand each other. It's also usually my experience of being in America - when I speak no one can understand what I'm saying.

I'm very superstitious about going on other people's sets. You have to ask permission of the director; you shouldn't just turn up and skulk about in the background. It's very rude. You have to ask them personally. It's like a vampire being invited into a house.
