District 9 (2009)

Thirty years ago, aliens made first contact with Earth. Humans waited for the hostile attack, or the giant advances in technology. Neither came. Instead, the aliens were refugees, the last survivors of their home world. The creatures were set up in a makeshift home in South Africa's District 9 as the world's nations argued over what to do with them. The tension between the aliens and the humans comes to a head when an Multi-National United field operative, Wikus van der Merwe, contracts a mysterious virus that begins changing his DNA.
