I try not to think retrospectively. It's important, as an artist, to look forward, always. I do try to take work that involves some challenge. If you approach a piece of work and you're going, "Yeah, yeah, I can do that," then that's kind of a red flag.

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.

It's a very organic kind of way that people are discovering it, by word of mouth, which I always think is the best way for things to grow. In terms of the affect it's been having on me, I don't even notice that. It's lovely to be able to talk about a piece of work that you're very proud of, that I think's a complex piece of work and not superficial and has depth to it.

I'm definitely a frustrated musician, though it's more in terms of wishing I was a better guitar player and songwriter. But I've never regretted becoming an actor instead. I think it's been a more pure form of self-expression for me. I luckily found something that I could aspire to be good at, whereas I never... I think I'd never quite reach that level of artist that I enjoy in the music world.

All I've tried to do as an actor is follow the good writing. That's been my main drive. It's not always possible, so when you do come upon it, like when I came upon this, you realize pretty quickly this is something you need to be involved with.

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.
