The first time that I came to New York to work properly was the mid-'80s, but I was doing eight shows a week. You have no life. Going to a punk rock club - or whatever the music was at that time - would not have been on my agenda.
There's, like, marks next to an actor's name or something, and boy does that go up and down! Somewhere in there, which always causes my mate Miss Ruby Wax great hilarity, I was offered a biopic of Frank Sinatra. Even I knew that was a bad idea! They'll throw anything at you at certain times. So, you know, to thine own self be true.
I was a student in London in the '70s, so CBGB really wasn't on my radar at all. Obviously, I was aware of the emergence of the Police in England and as an art student, I was very aware of David Byrne, but I suppose my musical taste at that time certainly didn't stretch towards the Dead Boys or the Ramones.
Older people say, 'Oh I loved you in 'Sense and Sensibility,'' and that's the only film they want to talk about. Equally, there are people who only want to talk about 'Galaxy Quest.' And there's a whole bunch of teenagers who only want to talk about 'Dogma.'
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.
Film has to be reflecting the world that we live in, and that's all you want to be a part of. Actors inhabit the same planet as everyone else. It's a weird thing that happens when you're an actor because people hold you up because you somehow embody in parts groups of people or people's hopes or something.
I have a photograph at home of Fred Astaire from the knees down with his feet crossed. It's kind of inspiring because it reminds me his feet were bleeding at the end of rehearsals. Yet when you watch him, all you see is freedom. It's a reminder of what the job is about in general, not just being in musicals.
Three children have become adults since a phone call with Jo Rowling, containing one small clue, persuaded me that there was more to Snape than an unchanging costume, and that even though only three of the books were out at that time, she held the entire massive but delicate narrative in the surest of hands.
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.
