In London, there must be thousands of people in the business of making films, whereas in Nottingham or Sheffield, you're probably talking about below a hundred. So there aren't thousands of people scrapping for the same money and for the same jobs. I went out in Nottingham the other night and there's a really beautiful community of people who are really supportive. It's not this back-stabbing thing, high-rent, high-cost, high-tension. Up here we are independent filmmakers and there's a lovely sense of camaraderie.

Bullying and violence that exists in someone can also be inherent in a nation without us knowing it.

In the Eighties, the landscape was changing. No one knew if they had a future. It's not like now. There was no satellite. Kids were still out on the streets playing all the time. For me, it was the last great hurrah! People don't take those chances anymore. Everyone's far too reserved. Men look like women, women look like men.

I suppose my dream was always about existing outside of London. Obviously the film world 10 years ago, when I first kicked off, was a very different landscape. Meeting anyone for a job on the crew, and on the cast, always meant a trip to London for me. But it's changed quite dramatically. You can't completely exist outside of what's down there, but things have changed massively.

As a director, your job can range from having to lean on someone to get a performance out of them, to someone being so built for the part that all you have to do is make them feel confident and comfortable and assured of what they're actually doing, and you just wind them up and watch them go.

You have to make a film and make it interesting, so you can't have a shot of you cleaning your teeth just because you did that. It's boring!

The violence at the end is about personal torture.
