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.

As a runner on a film, you are the lowest of the low, and yet you have incredible access to everyone. I can totally imagine that for actors in the middle of a Hollywood bubble, all they really want is a sense of normality, and that gopher can be a tap for that.

I draw and play the piano badly. But when I’m doing those things, I’m concentrating so hard there’s no room for worry. I find that onstage, too.

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 love the Potter films. I found them the most wonderful sort of escapism every year or two.

Ladies and babies, and mortgages, for that matter, can all wait. Acting has done a strange thing to me, though. I often sit there, thinking, 'I love this, but I wouldn't put my daughter on the stage.'

It's the weird thing Eton does - you're at school next to lords and earls and, in my case, Prince William, so you end up being used to dealing with those sorts of people.
