One of my favourite parts of acting is the clothes that you get to wear, because it's very important.

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'm not a big guy for research. You've got to take a risk.

Find out who you are and try not to be afraid of it.

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.

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

I had a really fantastic dialect coach that I worked very well with, and I was constantly surprised by the different intonations that the Russian dialect has.
