I hadn't really met Colin [Farell]. It's really weird to say: 'Oh, hello, I'm Kate...I'm Colin.. shall we?' That's a bit strange. Len was fine with it. We've gone through this experience with Scott Speedman before on the first Underworld move. It was our little version of swinging. We survived that.

The sea always offers up incredible stories of survivors' fortitude. Myths of a lot of countries have variations on that.

If you need to get in physical shape for a film and you have to maintain that for six months, at the start of the film, I was never able to do it.

You have the upmost amount of energy because you're not just having a cocktail at the end of the night. You're actually not drinking alcohol and you're keeping your body really clean and it's an amazing feeling to be getting out all the toxins.

I think, as human beings, we at times overvalue the intellect and we undermine the body. I don't mean a body externally and the shape of a body. I mean the intelligence of a body, the memories that a body can store, how a body feels emotion, and how a body processes emotion.

I've never seen a moon in the sky that, if it didn't take my breath away, at least misplaced it for a moment.

I love the grandiosity, how sweepingly entertaining films can be. And I think there's a place for films that pry more into the human condition.
