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.

'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.

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.

'Chappie' would be like 'RoboCop,' but hilarious. If you mixed 'Robocop' with 'E.T.' and it was... funny, that's what it is.

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.

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

There's a lot of evidence in evolutionary sciences that show that altruism and acting in ways that are empathetic to others are actually beneficial on an evolutionary basis.
