There has to be the popcorn genre element, or I don't engage the same way. I like action and vehicle design and guns and computer graphics as much as I like allegory. It's a constant balancing game. I want audiences to be on this rollercoaster that fits the Hollywood mould, but I also want them to absorb my observations.

'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.

Obviously I don't want to make a film that offends people, but the whole world is so politically correct - I'm not going to not do something because it may be politically incorrect. At some point, the metaphors and allegories break down. They disappear, and you just have science fiction.

If you look at the most meaningful science fiction, it didn't come from watching other films. We seem to be in a place now where filmmakers make films based on other films because that's where the stimuli and influence comes from.

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.

I do think that it's always okay to show too little. People will still be interested. So why show too much?

News is almost more interesting to me than other people's fiction, if that makes sense. But other people's fiction in terms of design is still incredibly interesting to me.
