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

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

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.

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

I do accents. Sometimes when I've had a few drinks, I speak in different accents all night long, and then at the end of an evening someone will say to me, 'Seriously, where are you from?'

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.
