I am a director and I think actually they're not that different - dramas and docs aren't that different. When I'm doing a drama I'm trying to make things feel as believable and real as possible. The hair, the make-up, the costume, the design, you're trying to make it authentic. And when you've got a documentary it's all authentic, so what story are you going to tell and how do you make it dramatic and exciting? It's the same thing.

As most of my films have been made in extreme locations. It's important to work with people who understand what they are getting into. They know that it will be tough, but it will be an unforgettable experience and hopefully we'll come out with a special, cinematic movie.

I used to work in TV and quit the job because I couldn't do it any more. I quite like taking my time over a film, five years is how long it takes me to work something out. And when you just do quick turnover, turnaround, I'm literally this is driving me mad, I want to find another living. I'll just have to find a creative way to tell the story.

I can now officially to the wife "It's work, darling" I have to watch racing. I have to watch every second. And actually, my wife who can't stand racing has got into it and once she understood the politics it becomes more interesting for non-racing people I think.

The more you know the better it gets. The more politics there is, the more you understand. Sometimes the races are terribly boring but what's going on off the track is great. And then it makes the race much more interesting.

There is so little time on a set to build up a working relationship with a new member of crew. It is tough to be polite, especially in an extreme location where we will not get a second chance to get the scene. It is such a stressful process that I like to work with people I know and can trust.

I love sport, so I'd love to do more stories if I can that deal with sport maybe. Other characters, actually the real guy is so interesting why would you want to get anyone to play them?
