It's really hard to describe, because for me when I first got the part there was no script. So I spent a lot of time - more time than I should divulge - just standing in front of a mirror, just trying to develop the physical vocabulary of what he is, what's important. The head pitched forward in pursuit; the fluidity and the points of focus and all these things. And that's all I could work on, you know? So am sitting there, like, 'What is a Terminator to me?' and I'm breaking it down and building it up from the ground.
