I only unwind at facials and massages.

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

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

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

I'm one of these people that if I have a nice holiday - like I have had in Turkey repeatedly - I go back a lot.

I found a lot of comfort in the fact that 30-odd people have been companions before me. I think that when there are so many people contributing so many things to the show, all you can do is make it your own. You can't try to emulate anyone, because who would you pick? The companions are very much the everyman, and the audience watches the story through their eyes, so they could be the person next door. And everybody's different.

I was very much into science when I was young - I wanted to be a marine biologist, then I wanted to be a doctor, and then something else, I was always changing. Acting didn't come up until much later, probably about 16 or 17. I thought, "Oh, I quite like this."
