I have a lot of stuff I want to talk about and offer up. It would be odd not to have ideas about something.

I went out to Mount Kilimanjaro, which I thought was very beautiful, but there were a lot of people there.

Unicef's education initiative does not seek to impose, but to initiate and integrate. It does, however, aim to address the huge bias towards education for boys at the expense of girls in so many cultures.

I was grateful to have two weeks to shoot this one scene in Harry Potter. It's a big, big scene, but they have to deliver. And they have high expectations.

I like to keep fit, but I never lift very heavy weights...

I have a great editor and I enjoy, in a masochistic way, being ruthless about my own performance. How do I know, but I think I'm quite good at saying, "That's no good. That's no good. That's it. That's it. That's good." And I'm with the editor who goes, "No, I think you're wrong. That's not your best." There's an initial point in the editing, if you're directing yourself, especially in my case, where you go, "Ouch, ouch, ouch, I can't watch this." And then, there's a point where you become hard-nosed and just take your neurosis away and go, "What's working? That's okay. That's okay. We can lose that, and lose that." You get objective about it.

When you get into the edit you'll understand what making a film is. You'll see all the things you missed and all the possibilities you have from what you shot.
