I have a piano in my living room that I mess around on a little bit and when I asked Len if I could find a piece of music, I went through a **** load of classical music to find something that I felt had a certain urgency to it, but also with a hint of melancholia and maybe a sense of longing. I found that which is public domain and I had a piano teacher to go through it with me.

I was never an A student, but I was really well behaved until I was 13 or so.

Initially, less appealing to me than the idea of a vampire that is drawn by some misgiving or drawn by some sense of longing that he can't quite satiate.

I mean you can go wherever you want with it really. No matter what story you're telling you're always representing some reality. You are always representing human beings, their fears, their shortcomings, their braveries, their doubts, their loves, their abilities, their brilliance and those things inevitably lead to bigger political systems, foreign policy and crime and religion. It's an action film. We are not taking a stance about big government.

I just recently realized. It's very strange. But doing fight scenes with Kate [Beckinsale], I was little bit more cautious. You can go harder with a guy, which I don't mean as an insult.

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.

Desperation will allow you to do incredible things in the name of survival.
