To force yourself out of the comfort zone, the main ingredient is trying to work in a world where you haven't been before, that you don't know the rules of. And that involves a lot of research, so you begin to see where the other people have been, but you are starting from as vulnerable and as low a point as possible.

If you have to be persuaded about something, you shouldn't do it.

I always say to anybody who's going over to America for the first time, 'Whatever you do, go and see a popular mainstream film with a big audience.' Because people shout out. You never get that in Britain. Everybody's so quiet, scared to laugh. It's like being in church.

One of the things in the Mary Shelley [Frankenstein] is that the creature tells his story, so this begins with the creature's point of view. So, it literally starts with the creature opening his eyes and is born - but is obviously in his 30s. But because they're the creator and the created we thought it would be really interesting if they could look at each other every other night and play each other's roles.

Everybody expects you to be qualified to talk about your films, but in a way, you're the least qualified person to talk about them. When you're finished, you don't watch them at all.

I have this theory that your first film is always your best film in some way. I always try to get back to that moment when you're not relying on things you've done before.

I like to hide behind my intellect. But the truth is, unless all of us start getting honest about what the reality is, things aren't going to change. If we all keep pretending that we know stuff and if everyone else would do what we knew and everything would be a better place, then nothing is going to change.
