If you've got a great crew it's intense, but its quite short. 'The Elephant Man' was longer than most, for an independent film. That was a 14 week film. But it was because of the intrinsic difficulties. We had to invent a different way of filming, because the makeup was so long. A working day for me with a full makeup on was nineteen hours. So obviously you couldn't do that twice running.

I think one of the things that is important, for me, though a lot of people would disagree with me, is that you be founded in theater so that you understand what an audience is, what kind of an animal it is and how to play with it. How to have fun with it, how to sympathize with it, all the things that an audience is. I don't think you're going to find that out unless you do theater.

I loved working with [ Lars Von Trier], but I've done two films before, so I was quite used to him.He's a man of incredible moods of course, but he's also a hugely perceptive man, and there's no getting away from that. And he's able to put that perception into something like film, so we're very lucky.

I mark a script like an exam, and I try not to do anything under 50 per cent. Similarly with the part. And also film is a peculiar thing, parts don't necessarily read in script form anything like as well as they can do when it comes to materialising.

I'd say the film to avoid is a director's second film, particularly if his first film was a big success. The second film is where you've really needed to have learned something.

In the end, the game is the same. Football is still football. Now, they may play with different formations, they may have a different idea of training, but the game doesn't alter. I don't mind how any performer - indeed, why should I? How arrogant of me if I did? - manages to get to what they have to get to. It doesn't matter how you get there, as long as it isn't going to destroy other people on the way.

The image onscreen takes you forward, it's the driving force of the piece and it's also the information that you're given.
