I've got to take a bit of a break from science fiction. As much as I've loved this stuff, I'm ready for a different century or a different time period as an actor, as an individual. Something that's, what's the word, something that's not involved with spaceships.

I've been acting for years and years, at prep school - school plays, that kind of thing. That was always very high on my agenda. I went to study English for two reasons. Principally because when I was in university, studying drama wasn't considered an option. You couldn't get a degree course for it. And so many plays and things that I was interested in landed themselves in a broader spectrum of literature.

I did worry about being in a science-fiction show. The bits that I was reading, I felt were funny, and I felt the man was childish, so I really did ask initially, "Is this for kids?" And the thing that came back immediately was like, "Hey, take a look at this whole thing again. This is definitely not for children. How can you think that?"

You can't find that moment when you became somebody else, because everything is in flux. So as it were, the torturous period where you are changing, you are transforming - I think that can be very hard on somebody's system. You don't necessarily realize that is what's happening.

From university, I tried to get into the profession almost immediately, and just got kind of kicked back in London, by lots of people saying, "Well, you know, we'll need to see you in something. And the easiest way for you to get seen in something is drama school. That is the best way to get an agent."

Film and television as a medium has only very recently begun to be taught at the great drama schools in the UK. When I was at drama school in the UK, I was there for two and a half years, and we did one week of television and film. It's right before you leave. It's like, "We've taught you Anton Chekhov and William Shakespeare, you are likely to be in a washing-up soap-liquid commercial."

I was convinced that I was going to be onstage for the rest of my life.
