I was obsessed with football when I was growing up.

We live in a bubble of the fantasy of death, but the reality of it is something that we obviously all face and have to deal with, at some point.

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.

In terms of how prudish Americans were in the '40s and '50s, I have absolutely no idea. I do know about the character that I play. And I don't think it's about being prudish. I think it's about trying to balance a sense of control in this man's life.

Americans are much more open than people in Britain.

So, if they're coming in and having to do scenes that involve nudity or sexuality, in some way, the utmost important thing is that everyone feels comfortable and safe. If there's any gray area, that's going to be a problem.
