You have a certain objectivity, as a member of the audience, and you can come away maybe being provoked into a certain discourse or a certain arena of questioning, regarding how you would deal with things that your character has to deal with. Whereas when you're doing a film, once you start asking, "What would I do?," you're getting the distance greater between yourself and the character, or you're bringing the character to you, which I think is self-serving, in the wrong way. The idea is to bring yourself to the character.

I remember some of the sets on "Alexander" were extraordinary and it would just take your breath away.

Pain seems to be easier, or melancholy seems to be easier to portray in a character. I don't know if that's because I'm a human being or because I'm an Irishman or both.

I love my kids. I'm crazy about them.

I don't go to the gym or practice yoga. And the closest thing I have to a nutritionist is the Carlsberg Beer Company. I just have the appetite of a pigeon.

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.

You consciously look after yourself, whatever that may be to you, whether it's going out for a few drinks and a bit of dinner, or just hitting the couch and watching TV, or going to the gym or yoga class. Just being aware that there's a potential for you to be in it and respecting wherever you find yourself is good enough.
