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.
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.
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.
When I am asked about influences, I always say I bow down to Fred Astaire, because when you look at him dancing you never look at his extremities, do you? You look at his centre. What you never see is the hours of work that went into the routines, you just see the breathtaking spirit and freedom.
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 approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
