In the story, I think as an actor you're just trying to fit into the world.

Whatever field you can do that, that's where you want to do it, and I think that's why people like David Fincher and Ridley Scott are interested in it, too, because when you sit down on a meeting in HBO and they're like, "More, more." You're just like, "Oh yeah, I love this." Sometimes it's a little harder in film. I think also it's a great audience, take advantage of it. It's a great audience.

I love the idea of longevity in this career. But [producing] is not about, "Let me do this because this might happen 20 years down the line." Sleepwalking wasn't a vehicle for me, it was a film that pushed the ­envelope. I want to produce good stories, versus creating a niche where I can look after myself as an actor.

I grew up in South Africa and I would look at maps and we were at the bottom of the world. There was this whole thing up there. I was always reading encyclopedias about the world. So travel was something I was always attracted to.

Right now the institution of marriage feels very one-sided, and I want to live in a country where we all have equal rights. I have so many friends who are gays and lesbians who would so badly want to get married, that I wouldn't be able to sleep with myself [if I got married before they could].

So how critics will perceive your film or your work, or whether your movie is going to make $100 million at the box office, or whether you are going to be winning any awards - well, you have no control over that.

I am going home and I think in a week or so, hopefully, I'll be done with all the press stuff, and then I can kind of into my cave and start preparing for "Mad Max."
