I think the level of devotion some sci-fi fans display turns other people off.

What would I like? Some very silly comedy where I don't have to think about anything, but it could be a lot of fun. And if it's not that, then I'll want to be involved in something where it's like, you're really dredged up to the neck in emotion, where it's as exciting as the premise of Battlestar.

Belief is everything when you're performing something. If you don't have the belief behind it, then that actually puts a shunt on the character. It's like, "Does the character believe this for a minute?"

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

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.

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."
