For people to come to you and say, 'Would you like to be a part of our show?' after years of 'Please tell me I'm good enough'... I can't tell you how wonderful it feels.

I'm not Irish. Just because I have red hair doesn't mean I'm a lucky charm, you know?

If I have the power to post 'Happy Birthday' on someone's Facebook page and make them feel really good, it feels really good to make other people feel really good. I love it. I'm a huge Facebook and Twitter person. And I love talking to my fans. It's fun.

When I got 'Lost,' I was about to not be able to live, so it was a fall-to-the-knees, burst-into-tears, 'I'm saved by this great role' moment.

Sometimes when you walk onto a set, there are very clear delineations. The crew don't talk to the actors and I hate all that. Everyone is the same to me and I always treat everyone in the same way.

I never did any sports at school. It wasn't until I moved to America, to New York, when I was about 20 that I actually thought that if I wanted to be an actress I might have to start working out.

I love science fiction stuff - I'm a bit of a dweeb like that.
