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!

I love the Potter films. I found them the most wonderful sort of escapism every year or two.

A lot of people think theatre must be much harder work than film, but anything histrionic or superfluous gets seen on camera so you have to work to distil it into a complete sense of what's true.

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.

My first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.

I'm trying to buy a house and set some sense of roots because otherwise you're constantly chasing one job after another, and you look back and you've had all these very extraordinary experiences with extraordinary people, but there's not a line of continuity to it.

I love the variety of films. In theater, you go into a room and the director runs the room, so you all work to his or her method. On film, if an actor or an actress is in for a day or two, the director has to get out of that actor what they need, so they have to change and adapt to that actor's technique.
