I'm as voyeuristic and intrigued as the next person as to how celebrities live.

As an actor there's a lot of scrutiny and, even when you've had success, it becomes about sustaining that success. A friend of mine described it as a peakless mountain. Even for Robert De Niro there's Al Pacino and for Pacino there's De Niro.

I did an interview once where I was asked who I found attractive and I went on about cartoons and Nala from 'The Lion King' - and it's a bit weird but various of my ex-girlfriends actually did look like Nala.

Making a film or doing a play are completely different experiences and entirely fulfilling, but completely unique. I also think one complements the other. People often say that theater is about flexing your muscles, and is actually real acting, whereas I sort of disagree.

I always try to describe making movies like summer camp, or some holiday where you spend all day, every day with a new group of people whom you kind of love and then never see again.

I go to the theater two or three times a week when I'm in London. Whereas I feel guilty going to the cinema in the middle of the afternoon.
