Then, at age 20, I discovered theater sort of by accident. Quite quickly, theater became more important to me than music. I began to realize that maybe my talents as a musician were quite limited, or had a ceiling to them, whereas acting seemed to sort of stretch before me. I got very passionate about it very quickly.

I'm kind of loath to pick one project over another or whatever. You go into every film sort of thinking it'll be your best work, and that's necessary. I think in this business, you really have to be forward-looking the whole time. I think nostalgia is sort of the death knell for any artist.

But television affords you, what you just described, to - over the course of 18 hours, now that we're doing a third season - tell the story of this man. You're not under any obligation, really, to do massive expositional stuff at the beginning. You're at liberty to say, "Come with us on this journey," and, gradually, you become aware of what his motivations are, what drives him, what his weaknesses are, what his strengths are. That's what I think's sucking people into these worlds, because it is kind of like a novel, you just go really, really deep.

I personally think if something's not a challenge there's no point doing it because you're not gonna learn much.

My only two constants are to challenge myself and to try not to repeat myself.

I come from a long line of teachers. Not only did I not go into the family business; I had an aborted law career and I played in bands. 'Disco Pigs' was my first professional acting experience.

That's what acting is about, Funny wigs and voices, that's what we do.
