'District 9' was a singular anti-Apartheid metaphor, and 'Elysium' is a more general metaphor about immigration and how the First World and Third World meet. But the thing that I like the most about the metaphor is that it can be scaled to suit almost any scenario.

You can build a brain the size of a room, theoretically. You could also build a silicone based life form and it could be sentient. There's no limit to the height that you can reach in terms of design once we figure out how to design things, theoretically.

Generally speaking, it's a very hard thing to wrap your head around that a drone operator in Nevada can be releasing munitions in the Middle East.

I think naturally I'm a very visual kind of person. If I wasn't in filmmaking, I'd be in something related to visuals. And I used to actually work as a visual-effects artist.

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.

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.

I am a firm believer that the pull for human beings is towards the good, generally outweighing the bad.
