I am more comfortable doing a drama.

When I read the script it was extraordinary and to work with Yorgos [Lanthimos] again was amazing.

I'll wait to see what the film [The Lobster] is, but it's set in a contemporary world, in America, there are hospitals and diners, parks, things that we will recognize and experienced ourselves but yet there's this similar kind of uneasiness through all the interactions and all the things that take place. It was unnerving reading the script. I kind of felt nauseous after reading it.

Making a film, you're in a really dark tunnel and the only kind of illumination is the shared experience you're having with your fellow cast and director.

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.

I've realized as well after five years of being on the road that if I'm going to four or five months of my life to something even if I'm overpaid, it's four or five months of my life away from home, away from my son, away from family and friends. I better believe in it on some level even if it's a big movie.
