I think that in the realm of commercial, popcorn cinema, the amount of message or smuggling of ideas you can get in there is quite limited. Like, if you think you're going to make a difference or change anything, you're on pretty dangerous thin ice.

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

I love the idea of people being themselves in films.

'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 grew up as an artist. Science fiction allows for design and creatures and guns and all the stuff that I like as well. So I think most of the films I make, I'm sure, will be in that category. But I can also see myself making a film like 'Black Hawk Down,' and I could also totally do horror.

It's just my maybe naive, optimistic view that whatever knowledge we gain, and if it comes to pass that we can somehow understand what consciousness is, if we can somehow create that, it will ultimately be used for the good.

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.
