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.
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 don't want egos and personalities on the set that make it more difficult to make the film. I don't want people who take the focus away from the movie and the ideas behind the movie.
I love the idea of people being themselves in films.
I was touching on the idea of the autonomous militaristic or autonomous law enforcement idea, but it wasn't the primary driving force.
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.
