District 9 (2009)

In 1982, a giant extraterrestrial spaceship arrives and hovers over the South African city of Johannesburg. An investigation team finds over a million malnourished aliens inside, and the South African government relocates them into a camp called District 9. However, over the years it turns into a slum, and locals often complain that the aliens are filthy, ignorant lawbreakers who bleed resources from Johannesburg.
