By the time I came to do the final ones [Harry Potter's film], I was working on something that was massively successful. There was a huge difference in indulgence and all sorts of stuff. A very big difference in peoples' attitudes. They were very pleased with themselves. In human terms, it was quite interesting to see the difference.

I have lots of favourite memories but I can't say that I have a favourite film.

I think you can fan the flames, but I think in the same way that a mathematician is a mathematician - He's not taught to be a mathematician. He either has a feeling for equations and an understanding and delight in it, not only in the purity of it, but in its beauty as well.

If you listen, you learn; if you talk, you don't.

The common misconception is that we create films for ourselves. And I really don't do it for myself. I get stopped in the street by people saying, "Do you mind if I say this about your work?" Do I mind? I'm delighted. I do it for you. It's not for me. It's my living, yes, sure.

I often say, with something like 'The Elephant Man,' had it been an American series for television, where you have to sign your life away for seven years...well, maybe I would never have made 'Sailcloth.'

Very, very broadly speaking, you can put directors into two areas: One for whom you work, and the other with whom you work. And I prefer the latter, for obvious reasons. It's a great relief to feel that you're working with someone rather than for someone. You don't feel that you're being tested, as it were.
