I caught the trailor for this the other day. It looks pretty interesting if you like these different SCI-FI type movies. They are putting a lot of effort into thier marketing for this. You can tell by the website. I would post the Trailer here, but You Tube is blocked at work.

District 9 is based on Alive in Joburg, a short film directed by Neill Blomkamp, Sharlto Copley, Simon Hansen and Shanon Worley. Copley also portrayed one of the interviewed policemen. The short film is about aliens landing in South Africa and becoming confined to a specific area and forced to work. In the movie these aliens are called "Non-Humans" and are overseen by Multi-National United (MNU), a company which is utilizing alien technology.
