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'm quite ignorant about fashion and I'm colourblind, so it's all a tad tricky. My only knowledge of that world comes through Christopher Bailey, whom I first met in 2008 when I did a campaign for Burberry that featured musicians, artists, actors and sportsmen.

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.

In England we have this saying about Marmite: people either love it or hate it. That's like a lot of the movie work I've done. People either find it repulsive or find it really interesting and get engaged in it.

I think all actors have a similar deal. You want some people who understand. Although it looks great - and is great - there are also shoddy moments when you feel really rotten, and when it's going well, you're not allowed to complain.

Two years ago, I shot 'Pillars of the Earth' in Budapest - it was a big part, but I had a lot of time to sit around and visit cafes.

My first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.
