You know what it's like to feel anxious - it's horrible feeling anxious. It's stressful having that feeling, having butterflies in your stomach, even for a day, and you don't sleep at night.

It was pretty daunting. Normally, I never go to a gym, but before we started shooting, I thought I'd better. I reckoned I was in really good shape, and then I looked around and I was half the size of everyone else. A lot of these American actors have this - in my view - misplaced view that they have to look like Action Man. The trouble is, they all run the risk of being interchangeable.

It's good to be busy on a film set because there is a lot of sitting around, so if you've got two roles to play at one time, then that's great to do.

I think people like to be scared. I think people like tension and suspense in a movie.

Temperamentally I'm not a natural producer, because I don't have the patience.

I guess I'm just good at playing repressed individuals. I'm lucky because those are often the roles that catch people's eyes.

I'd lived in LA for two years and I said to my agent that I wouldn't do any more network TV, because my family and I had just made the decision to live in England. It would be a whole year in LA shooting network TV.
