I used to be absolutely addicted to the gym and I do still love it.

Whether people watch Doctor Who or not over here, everybody knows about it. It's a British icon, it's so part of the nation.

I love hotels for their solitude and comfort, but I believe a seedy one can have as much promise as a plush one.

Nobody in my family is in the show business, and none of my friends were. I went to a very academic school that actually - when I got to the point of wanting to pursue acting, they just had no idea how to do that, because all of their contacts were very academic.

I appreciate individualism.

David Tennant is a massive fan, and grew up dreaming he would be the Doctor Who one day. So I did feel, when I first got the job, "Right, now I've got to do loads of research into absolutely everything Doctor Who." But that's not possible to do in a short space of time. So my knowledge has been growing and developing as I've been doing it, and that's been fine. That's been appreciated by the fans, and the executives never expect me to be brushed up on absolutely everything.

I only unwind at facials and massages.
