Filming is about continuing to be alert and to think, and I find it quite exhausting.

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.

I'll always find the things that make a role complicated!

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.

What's really interesting about actors, is that we all have opinions on how people's careers look, but I think you never have any idea of your own, or what other people think of you.

I'm by nature someone that quite likes to understand how things are working, likes some sense of structure, and I've fallen into the worst possible trade for that.
