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.

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.

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.

A lot of people think theatre must be much harder work than film, but anything histrionic or superfluous gets seen on camera so you have to work to distil it into a complete sense of what's true.

I do get stopped a bit now and then, but I can go to the supermarket and on the Tube without being noticed. It's usually me that gets starstruck, especially by TV stars.

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.
