I love the variety of films. In theater, you go into a room and the director runs the room, so you all work to his or her method. On film, if an actor or an actress is in for a day or two, the director has to get out of that actor what they need, so they have to change and adapt to that actor's technique.

The depiction of the exterior as opposed [to] what you're feeling inside is always so different that it's impossible to know what is right.

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.

I'm just one gigantic ball of rancid fear and self-consciousness. I'm entirely fueled by fear, so the fact that I knew it could be a catastrophic disaster made me unable to sleep, and made me work quite hard.

It can be a miserable profession, acting, because you always want what you can’t have.

I'm trying to buy a house and set some sense of roots because otherwise you're constantly chasing one job after another, and you look back and you've had all these very extraordinary experiences with extraordinary people, but there's not a line of continuity to it.

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.
