In England we have this saying about Marmite: people either love it or hate it. That's like a lot of the movie work I've done. People either find it repulsive or find it really interesting and get engaged in it.

I find that what doubt does, or fear, is it makes you come up with as many ideas as you possibly can. And on film that works 'cause you're then handing over that fear to the director, who has to make sense of all those options!

You never know what's right, what you feel inside versus what is portrayed.

I walk around talking to myself in accents. Usually people look at me like I'm a complete fruit loop.

I had never been to a fashion show before going to the Burberry show last month. It was an extraordinary spectacle. I was incredibly green and had no idea what an undertaking it is. I also have a new respect for models because they are so close to the front row and must be so self-conscious.

If you've loved something and then in some ways you become a part of it, you just don't want to be the one that screws it up!

Two years ago, I shot 'Pillars of the Earth' in Budapest - it was a big part, but I had a lot of time to sit around and visit cafes.
