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.

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.

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.

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.

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.

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

I genuinely try to make movies I'd want to go and see, movies that are a bit more challenging.
