It can be a bit annoying if another actor is trying to talk to the director and the wife is sitting on his lap.

Most of actor's work is done at home, in your hotel room, in the wee hours of the morning thinking and reading and feeling, walking around and listening to music. It really just because an internal exercise, whatever skills. It's great if you have to learn something new for a gig and designing a character physically is always fun but it does become an internal exercise in separating the wheat from the chaff.

It's so technical. It's nothing personal. You're not fighting really, you're missing each other by a half of foot at least, ideally more and you get a few knocks and bruises. But with the kissing, you do kiss someone. Its lips on lips.

Life is apogee, apex, decline; life is death - and everything else is open to discussion.

My Dublin wasn't the Dublin of sing-songs, traditional music, sense of history and place and community.

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.

Sometimes I have experienced at the start of a film you're very excited and enthusiastic and you've done all your preparation internally and externally and you start the film and it's all go... Then your attention goes somewhere else. Your energy goes into telling the story, so you don't have the same amount of energy to be objective, and that's okay because sometimes you become a subject of the story and you're inside it so much that you don't need to keep on looking on the outside.
