I think in my job, it's quite difficult to find work on television... you don't necessarily want to get a profile for something that you don't fully believe in.

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

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.

Never, ever wear three-quarter length trousers. Even in the summer.

It's a thrilling world, and people really like stories about secrets, which is the essence of a spy drama.

It sounds maybe a little old fashioned, but the parts I want to play and I do play, you don't want to inject too much of your own personality. What you sacrifice then is a slight mystery.

'Serious acting' is the kind of acting that I don't ever respond to.
