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

The fact that natural selection and evolution crafted essentially carbon and water into a mechanism that can think and be conscious means there's nothing in physics that says you cannot do that to a greater degree.

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.

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.

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.

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.
