I'm fully aware that 'Doctor Who' will always, always be part of my life, and that's not something I would run away from in the slightest. I wear it with pride, definitely.

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.

The way sci-fi works, you can never die.

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 appreciate individualism.

I couldn't sustain myself if I skimped on food - I work 16-hour days, I need the energy, I can't afford to be stingy on what I eat.

I know it's really square but I'm one of those people who piles on the factor 50 as soon as I'm outside.
