In the case of two actors connecting with each other and trusting each other, our bodies have memories without us having to consciously think about it, so rather than think, "Oh, I must think about my daughter dying," you just let that go and trust that you have all the emotions you need in there, and by losing yourself in the scene, that stuff kicks in without having to spend the day thinking about horrific things happening to your own child.

The first job I ever did in the theatre, I was supposed to be a genius piano player. I couldn't play the piano, but you just sit there at a piano like you're playing, and suddenly all this amazing music comes out and the audience believes you can do it. It's the same with computers. I love scenes where there are people yanking at monitors, "yes I'll put you through now," and you know they're just doing that. But you can look brilliant at all this technology. I love it.

And so, in terms of setting the right tone and finding a way of presenting all of these things, that creates a cohesive whole and doesn't alienate the audience, is tough. That's a challenge. And I think the tone of a lot of shows is discovered through experimentation and actually making it. Eventually, it starts to cohere.

I was obsessed with football when I was growing up.

It's interesting that in searching for monsters to play you often end up playing leaders.

I think I'm becoming more relaxed in front of a camera. I suppose I'll always feel slightly more at home on stage. It's more of an actor's medium. You are your own editor, nobody else is choosing what is being seen of you.

I perceive and relate to the world through where I grew up; that's part of me. It's what I judge everything else against.
