The actor Sharlto Copley (Wikus in District 9) makes a great appearance in here too. You can absolutely see how the concept built out in this short 6:30 piece was just born to be created into something bigger.
There's a political message in here too. The footage of South African locals talking about aliens was actually footage of director Neill Blomkamp interviewing Soweto residents about other Zimbabwean and Nigerian migrants.
Kind of an obvious allegory going on here-- aliens being a stand in for the 'other,' even among South Africans who suffered under apartheid.
District 9 was mind blowingly awesome. Can you even believe this is Neill Blomkamp's first feature film? I'm blown away, impressed and inspired.
