I often stop when I'm doing something, in the middle of rehearsals or some other job, and I try to take a minute to think "Okay, this might be as good as it gets, so drink it in, appreciate it now". So far, I've been lucky because another job has always come along to equal the last.

I still am a geek, I don't think there's anything wrong with it. I see no shame in having an unhealthy obsession with something.

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.

I'm quite happy to leave it still feeling that way, leave it before it starts feeling like a job. ... I have such fond memories of watching 'Doctor Who' when I was a kid and growing up, that if I've left anybody anywhere with memories as fond, then I feel like I've done my job.

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

I always like seeing people transforming themselves, in whatever way that might be, and a different accent is part of that.

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.
