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.

Actors who perhaps are super-confident and have absolute belief in themselves I always admire, because I can't really be like that.

On so many levels, acting in film and TV is so much the sum of its parts, and somewhere in there, there's an alchemical thing that makes something happen or not - that makes something connect or not. Now, of course you want to make work that people see, but the enjoyment I get out of acting is playing characters.

Listen, acting is not surgery, it's entertainment. You're doing something to hopefully move people, to make them laugh, to transport them. But actors are vulnerable, and the reason we're vulnerable is that we're always trying to recreate human behaviour.

I'm quite ignorant about fashion and I'm colourblind, so it's all a tad tricky. My only knowledge of that world comes through Christopher Bailey, whom I first met in 2008 when I did a campaign for Burberry that featured musicians, artists, actors and sportsmen.

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.

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!
