I'm not very glamorous.

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.

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'm terrified of bugs and I travel with sprays, lotions, potions; the lot. I have to check the room before I go to sleep and if I come across a bug and fail to remove it I have to sleep in a separate room as I'm paranoid that I'll be taken advantage of as I sleep.

I constantly make lists and itineraries and then can't stick to any of them.

I only unwind at facials and massages.

My own style is one of not much effort.
