My favourite stuff is visual, and I always want to work with visual artwork. I think it depends on the person, but for me, photographs of an image of something interesting or inspiring is worth a lot more than words to me. I think every concept I've come up with and turned into films or that will be hopefully become a film comes from images first.

This whole notion that the robot has to declare nuclear war is one part of the discussion, but it may not be reality. Reality is, maybe it can empathize to a far greater degree than we can and experience a way wider range of emotions. So, why not have a robot that can do that?

I think the world of 'District 9' has a lot of race and oppression-based ideas that I would still like to explore in that world.

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.

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.

Deleted scenes are like in a middle gray zone. It's like, well, they're deleted because they're not good or you lost the battle and you couldn't put them in the movie.

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