The secret is not to make a film that causes something like Virginia Tech to happen. The secret is to make a film that stops it happening.

I think directing in a team is a really good idea because it stops the cult of the director as God straight away, and also you're discussing things on set so it opens it out to everyone and it becomes a totally collaborative thing. And you have someone who supports you when you're feeling a bit insecure.

We are quite different: I'm relaxed, and I get ready for races really late, whereas Jonny is really organised and punctual. I like to lead from the front in the run, whereas Jonny might hold back.

I hope the next actress offered millions to play the 'fat girl for the day' stops to think about this before she signs the contract - even if just to ask, like any professional actress would in any other situation, 'Why does she weigh 350 pounds? And why me for the part?' If the director can't answer these questions, don't do the movie.
