Once you click into a character, to a certain degree, you can do a lot else. You can do other stuff, then come back and click right into the character. It's sort of funny that way, the way the mind works. Once it's there, it's sort of there. For the stage, for example, all through the day, you're not onstage. You're living your life, la-la-la, then the lights go down, then boom! All of a sudden, you're in this thing. There's a kind of reflex muscle trigger that happens, and all of a sudden you're back into the role. It's just getting there in the first place that's tricky.

I like finding things out beforehand, because I'm nervous in disposition, and I worry that if I don't do anything, then I'll turn up and I still won't really have a sense of it, and it might be too late. So I like to get things as organized as I possibly can in my own head, to apply myself to the work before arriving to a late-in-the-day rehearsal, or in extreme cases, the first day on set.

I remember being very affected by what was going on there towards the end of Apartheid. And the subject is still very pertinent, politically, to what's happening around the world today, in terms of negotiating peace talks. I had always been interested in this period of change in South Africa, generally, for a variety of reasons.

Id never really considered film. If Id thought about film more growing up, I probably would have changed my name. I had no concept of my name in lights.

David Mamet was great to work with. He was everything that I thought he would be as a director. He's incredibly articulate, an easy collaborator. Extraordinarily knowledgeable about film and writing.

Practically everybody I've ever worked with, I'd like to work with again. I had a great time with the people that I've worked with, and the directors, and a lot of the casts. There's really nobody where you'd say, "Oh, I got X, Y, and zed again! Gahhh, no!" It really brings a smile to my face, because in 95 percent of the cases, people I've worked with, I'd be thrilled to work with again.

I'm constantly looking to see whether I look the same as I did earlier, whether I've put on or lost any weight.
