I never expected to have any kind of film career, to be honest. It was all a bit of a surprise. But I was in a big hit play on Broadway. America, as many people will say, says yes more often than we do. And so I was suddenly surrounded by people saying yes. But I was aware that was 'cause of what I was in. It had a big impact.

When I get off the plane in England I always feel about two inches shorter.

In theater, you've got to be aware of your whole body because it involves stamina. It involves two-and-a-half hours and a sustained release of energy, maybe for six months.

I get stage fright and gremlins in my head saying: 'You're going to forget your lines'.

I was coming from a very cerebral, dark, difficult, layered play by Christopher Hampton and doing an action movie in Hollywood (Die Hard) with explosions, and I was holding a gun.

One thing I will say - my job gets harder and harder. The more you understand about what you are capable of, the less the instrument can do it physically. It's an inverse equation, if that's the right phrase. I just slammed those two words together. It sounded right.

The directors you trust the most are the ones, when you ask them a question, they've got the guts to say, 'I don't know.'
