I was touching on the idea of the autonomous militaristic or autonomous law enforcement idea, but it wasn't the primary driving force.

I've learned more, and I understand the process a bit better now. I can try to see how long I want to take in each aspect of the filmmaking process, and then arrive at around the two-year end mark.

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.

'District 9', 'Elysium' and 'Chappie' were all born out of some visual concept first. 'Chappie' is the imagery, because I think I'm a visual person first, of this ridiculous robot character. It's much more comedy based and in an unusual setting.

I actually think Johannesburg represents the future. My version of what I think the world is going to become looks like Johannesburg.

If you just compare South Africans to the rest of the world, I think that white South Africans, and especially English-speaking white South Africans, are exactly the same as Brits or Australians or New Zealanders or Canadians or Americans.

A lot of parts of L.A. are interchangeable with suburbs in Joburg. Very big, ostentatious houses with palm trees and lawns. Lawns are very important. Never underestimate lawns.
