I don't care if people perceive me as always selling out because I'm doing a studio picture. For me, the whole thing is you should be diverse in your choices; that's the beauty of being an actor, you should be able to do that.

I like the little bit of distance that London affords me and I like living in a world capital. I like having the culture at my fingertips.

At the moment I'm doing this space movie, so I'm obsessed with physics and space travel. I know three months down the line it's gone. Then I'll be able to superficially say stuff about space.

I like watching film, I go to the cinema, but a lot of times I go to see kids' films.

All I've tried to do as an actor is follow the good writing. That's been my main drive. It's not always possible, so when you do come upon it, like when I came upon this, you realize pretty quickly this is something you need to be involved with.

It's always nice to be challenged.

And, for any performer, to be able to go deep into character is fantastic. In film you only get to do that if you're the leading character. But in television you get 18 hours to really test the audience and take them to the edge of how far they will go with this character. I can step over this line and I love that.
