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.

The medium is secondary to the stories.

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 think there's such a thing as a performance gene. If it's in your DNA it needs to come out. For me, it originally came out through music, then segued into acting and came out through there. I always needed to get up and perform.

I'd love to work in America, some of my favourite films come from America.

It was very much about performances, the whole ensemble thing was just great - everybody working together. Sometimes it didn't feel like a film set. It wasn't technically driven, it was very, very enjoyable

I don't know if anyone will ever sit beside me on a plane again.
