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.

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.

And the very fact of how you speak somehow influences who you are. The way you move, the way you think, it seeps into your being, and it's quite hard to really break that down entirely.

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.

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.

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.

We seem to spend a lot of our time in very small spaces spouting a lot of dialogue very quickly.
