Further to my review of "District 9" yesterday, a friend mentioned to me last night that the original short film upon which the feature film is based, "Alive in Joburg", was available on YouTube.
I just watched the short, and it's really an amazing piece of work. I can imagine seeing that and completely being on board to letting him make a full-length film version of the story. You can see a lot of the same themes and styles that are expanded upon in the feature film. The actor who plays Wikus, the lead in "District 9", also has a small part in the short.
Here's the link in case you want to go there directly.
