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.

I only unwind at facials and massages.

I've had journalists beg me to please say something negative about my estate.

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.

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

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