South African director Neill Blomkamp based this movie on a short film of his called "Alive In Joburg." It has no known stars in it, unless South African audiences know them. Peter Jackson, who directed the "Lord of the Rings" trilogy and "King Kong," produced. That alone may be enough recognition to market the film to the broad audience that it deserves. The script is wonderfully layered, the concept both frightening and funny, with all kinds of political and sociological connections. The execution is great.
