I think it would be self-indulgent to go, "Oh, I'm going to make this character different by giving him a quirk of some kind." I don't think that serves the story, particularly. But even very similar scenes with a different set of actors, a different set of circumstances, it starts to evolve as a different character.

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.

Some people live more in 20 years than others do in 80. It's not the time that matters, it's the person.

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'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 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.

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.
