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 De Niro there's Pacino and for Pacino there's De Niro.
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.
Listen, acting is not surgery, it's entertainment. You're doing something to hopefully move people, to make them laugh, to transport them. But actors are vulnerable, and the reason we're vulnerable is that we're always trying to recreate human behaviour.
Most actors hate watching their own films because all you can see is the glaring mistakes, your own tricks and ticks.
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.
On so many levels, acting in film and TV is so much the sum of its parts, and somewhere in there, there's an alchemical thing that makes something happen or not - that makes something connect or not. Now, of course you want to make work that people see, but the enjoyment I get out of acting is playing characters.
