When I first got the job, I was told nothing about my character. She's an anthropologist and she's tough, she's a female Indiana Jones. That's what I went into [Lost] knowing.

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.

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.

You know I hate watching myself on TV, I know a lot of actors say that, but it's true for me.

All I do is watch TV and films, and when I'm not doing that, I'm making them. I need a hobby!

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

The danger with playing someone tough is that the character can become two-dimensional and mean and nobody likes her.
