There's some people that obviously abuse social networking or whatever, but I think it’s a fantastic idea. I’ve never had any bad encounters with any of it.

It's huge in the U.K., if someone's doing well, to put them down. That's what we do all the time. It's kind of like a cultural thing.

I'm so excited to be working on Doctor Who as it's such a big and important part of British Culture. I can't wait to meet the cast and crew and start filming, especially as we'll be shooting not too far from my home town.

Sometimes you miss friends, and it's hard for them, as well, when you're just gone for a long time. I can't just go and see them any time I want because when I'm free, they may not be free, but I definitely wouldn't change it, ever. But, when you find really great friends, that doesn't matter, and I'm lucky to have some people who really, really look after me and look out for me. I definitely wouldn't ever change it.

Whether I like it or not, I've become influential to people.

You know sometimes when you're in a really bad mood and you're not sure why? That's how I get sometimes.

I use Twitter a lot. That's how I communicate with international fans. Everyone's always really, really nice.
