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

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.

It's part of developing the whole state of how cinema is; everyone is looking out and engaged rather than it being just a financial thing or sitting back, waiting for scripts to turn up.

There's no way you can shoot low-budget stuff on lots of locations. It's just a practicality thing because every time you move, it costs time and money.

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.

Film is more of a dream when you're younger. I found it almost impossible to see how you would get into the industry having no connections, nobody in the family being anywhere near it and never meeting anybody that had been on a set.

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