Really I just want to get on with my job, which is to pretend to be lots of different people. Simple as that.

I do sometimes play characters that are a bit ambiguous. You've got to be brave about that sort of stuff. I like the sense of people not feeling too secure, not immediately knowing what they have in front of them.

I can totally understand why people say: 'I'm going to do this T.V. series so that I can buy a flat'. But you've got to see what's of value to you as an actor.

The kind of actors I admire move through different characters and genres.

Audiences like to be challenged and to be actively involved and try to guess an outcome.

But there's a difference between privacy and secrecy, and I'm not a secretive person.

If one story becomes too hot, then you can't forget it. As an actor, you want to remain fluid.
