When I was in my early 20s, I was quite into Japanese animation. It's like the same thing that I end up always saying which is, imagery based stuff is the thing that really gets me.

If the population curve is on an exponential growth, and the resources are on an exponential decline, what happens first is you get increases in wealth discrepancy, which means that you get rich pockets of gated communities with security guards outside them, and you get more and more poverty outside that area.

I love the idea of people being themselves in films.

Johannesburg is weird, because half of it is like Los Angeles. It feels like just wealthy parts of L.A. But half of it is severe slummy, something like Rio De Janiero or something. So it's kind of weird, because it's both happening at the same time.

If it takes several billion years to develop the building blocks which you need, like RNA and DNA, and then those can build multicellular life and then multicellular life can be honed with natural selection to a point where it becomes sentient like us, then at some point that sentient being can begin to manipulate the matter around it to build better sentient life.

I had artists that refused to work on Chappie if they were working on a design that actually said Denel on the side of the thing. But anyway, it's the blurring of fiction and reality that was appealing and I certainly did not want them to be in the movie and not be themselves.

There are loads of sociopolitical, racial, class and future-planet situations that really interest me, but I'm not really interested in making a film about them in a film that feels like reality because people view that in a different way. I like using science fiction to talk about subjects through the veneer of science fiction.
