I love working with horses. People say you shouldn't work with animals and children; that's wrong. You must only work with children, because you only work eight hours a day and I love working with animals. Animals have an honesty that human beings reach to find in their lives at the best of times.

I've got plenty of love in my life already in the form of my sons and a few good friends who I value dearly.

Beauty is undefinable in language. It's something that you see when you see it, or you feel when you feel it, or you hear when you hear it. It usually encompasses all five of the senses. It can't exist without it being a somehow sensorial experience. But, I don't think it's quantifiable. Nothing is really quantifiable. Nothing is certain in love and friendship. We all try to understand these things.

The first time you hold your baby in your arms, I mean, a sense of strength and love washes over you. It washed over me and I never thought that possible.

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.

Audiences will see what they want to see. Some will come out, hopefully enjoying two hours of action. Some people will find themselves gravitating towards the emotional dilemma that the characters find themselves in. Other people will see that there is some layer of subversions to the storytelling aspect of poking a finger of judgment at certain governments to the idea of foreign invasion, others maybe false pretenses.

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.
