There's no question that how Johannesburg operates is what made me interested in the idea of wealth discrepancy. 'Elysium' could be a metaphor for just Jo'burg, but it's also a metaphor for the Third World and the First World. And in science fiction, separation of wealth is a really interesting idea to mess with.

If the population curve is on an exponential growth, and the resources are on an exponential decline, what happens first is you get increases in wealth discrepancy, which means that you get rich pockets of gated communities with security guards outside them, and you get more and more poverty outside that area.

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.

I think people are destined for something incredible if we don't wipe ourselves out, but I think we're going to wipe 90 percent of ourselves out.

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.

I never really think of something in terms of what not to do. It's always what's appealing or what's cool.

When any young director gets hired by a studio to do a $125 million film based on a preexisting piece of intellectual property, they're climbing into the meat grinder. And what you're coming out with on the other side is a generic, heavily studio-controlled pile of garbage that ends up on the side of Burger King wrappers.
