Director Neill Blomkamp teams with producer Peter Jackson for this tale of extraterrestrial refugees stuck in contemporary South Africa.

It’s been 28 years since the aliens made first contact, but there was never any attack from the skies, nor any profound technological revelation capable of advancing our society.

Instead, the aliens were treated as refugees. District 9 film.  They were the last of their kind, and in order to accommodate them, the government of South Africa set up a makeshift home in District 9 film as politicians and world leaders debated how to handle the situation. As the humans begin to grow wary of the unwelcome intruders, a private company called Multi-National United (MNU) is assigned the task of controlling the aliens.

District 9 Movie

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 movie as the world’s nations argued over what to do with them. Now, patience over the alien situation has run out. Control over the aliens has been contracted out to Multi-National United (MNU), a private company uninterested in the aliens’ welfare – they will receive tremendous profits if they can make the aliens’ awesome weaponry work.

Wikus quickly becomes the most hunted man in the world, as well as the most valuable – he is the key to unlocking the secrets of alien technology.
