I mean, you know, while I'm acting on stage I'm ranking quite high, but in a room with Barack Obama I'm probably into negative digits. I never feel very famous.

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'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.

All roads seem to have come back to Doctor Who in our life. But, no, it was a huge part of my growing up. I was a massive fan and it certainly inspired me to get into acting and to be ... one of those people that tells stories on TV. That was a huge part of my childhood.

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

An accent has to do with the way your mouth works and the sounds that come out of your head, but somehow it informs everything about you.

I was always going to act, literally ever since I was tiny. In fact, I have Doctor Who to thank for that. I wanted to become an actor after being obsessed with Tom Baker, the fourth Doctor Who, in the 1970s. His was the definitive performance of all time in anything.
