When I was pregnant, I did Kundalini yoga. It was all closing your eyes, dancing around, and putting your hands together to form birth canals for people to pretend to be a baby coming out.

I have a computer and an iPad, but I have no interest in Twitter.

Given the amount of work and time my mum devoted to my sister, it left me a lot of time to play on my own. I mean, I played with kids in the street all the time, too - I definitely wasn't denied a childhood. But I do wonder whether, in a sense, acting was my way of getting noticed.

To be honest, 'Doctor Who' fans are a mixture of crazies plus solid citizens, but they're relentless.
