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

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.

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 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...

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’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...
