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.

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.

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

The goal is always just trying to stretch yourself as an actor.

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.
