I think doing different accents is part of the job of acting, really. It's something else that I quite enjoy the challenge of, to be honest.

I've always been a geek and slightly awkward… slightly umm… I was never the cool kid at school.

If you speak in a different accent, you begin to move in a slightly different way. You think in a slightly different way. It's part of trying to find what makes a character.

It's very hard to be objective about something you're in, especially when you set it up against things that you experienced as a child.

There's a morality... I think there's a moral compass but whether that comes from religion or just from being a good person, and where one starts and the other begins... I'm a good person, I hope. But I'm never as good as I want to be, never as nice as I want to be, never as generous as I want to be.

Moths are the ones that freak me out. It's something to do with the way that, if they get squashed, they turn to dust. There's something very wrong about that. It all feels a bit Gothic.

I think if my eight-year-old self could see me at the Royal Albert Hall winning a prize for playing the Doctor on telly, he would need a stiff shot of Irn-Bru.
