The Prawns of District 9: Biology, the Ship Over Johannesburg and the Allegory

Neill Blomkamp's film began as six minutes. Alive in Joburg (2006), a mock documentary short shot in Johannesburg, interviewed real residents about immigrants and cut their answers against footage of aliens; Peter Jackson saw it, his planned Halo film collapsed, and he produced District 9 (2009) for $30 million instead. The feature keeps the short's premise and its form. In 1982, the film's newsreaders recount, a mothership the size of a city drifted to a halt over Johannesburg; after three months of silence a team cut into the hull and found roughly a million aliens, sick and starving, in the dark. They were moved to a camp under the ship that became a slum, District 9, and by 2010 the private contractor Multi-National United has been hired to move them again, to a tent city far from the suburbs called District 10.

The story is one bureaucrat's week. Wikus van de Merwe, played by Sharlto Copley in a largely improvised performance, is the MNU official serving eviction notices when he is sprayed with a black fluid an alien named Christopher Johnson has spent twenty years distilling from scavenged technology. The fluid begins turning Wikus into an alien, which makes him the only human who can fire the aliens' DNA-keyed weapons and therefore the most valuable object in Johannesburg. The film follows him from the MNU laboratory to the slum to the ship, and ends with the mothership gone, Christopher promising to return in three years, and Wikus, fully transformed, folding a metal flower in the ruins for his wife.

The aliens stand about two metres on digitigrade legs, with a hard segmented exoskeleton, four arms (two large, two small at the chest), mandibles, antenna-like tendrils and eyes set wide on a flattened head; they are built on an insect plan and behave, in the camp, like a displaced population rather than a hive. They eat almost anything and have a craving for cat food, which the Nigerian gangs in the camp sell them at ruinous prices. Their technology runs on their own biology: weapons fire only for a hand with their DNA, their ship's fluid is grown as much as made, and their armoured exosuit responds to a pilot it recognizes. The film shows them as engineers with nothing to engineer, and Christopher as the one who kept working.

"Prawn" is the word the humans use, and the film is exact about what it is: an insult that turns a people into vermin, borrowed from the Parktown prawn, the giant king cricket Johannesburg residents find in their gardens and kill with a shoe. The design took the resemblance seriously, with Weta Workshop building the aliens as computer-generated characters animated over actors on set, so that the slur and the creature match. The species' own name is never spoken. That silence is a choice: the film is told from the humans' side, through news footage and interviews, and the humans never asked.

The title is the tell. District Six was a mixed neighbourhood of Cape Town that the apartheid government declared a whites-only area in 1966 and bulldozed over the following decade, forcing out some 60,000 residents to townships on the Cape Flats; the film's District 9 is that history with the residents replaced by aliens and the government replaced by a contractor. The eviction notices, the signs reading "for humans only," the pass laws and the medical experiments in MNU's basement are all lifted from the record of apartheid, and Blomkamp, who grew up in Johannesburg, shot in the real Chiawelo section of Soweto, where residents were themselves awaiting relocation from shacks to government housing.

The film was also about the year it was made. In May 2008 xenophobic riots across South African townships killed 62 people, most of them migrants from Zimbabwe, Mozambique and Malawi, and the film's treatment of the aliens as job-stealing, crime-bringing outsiders reproduces the language of those weeks. Its portrayal of the Nigerian gang in the camp drew a protest from Nigeria's information minister, who asked cinemas to pull it; Blomkamp said the gang was drawn from Johannesburg's actual criminal economy. Both readings are correct, which is the film's method: it does not use aliens to talk about racism in general, but about a specific city in a specific decade, and lets the audience recognize the rest.

A vast, silent object hanging over a city is the one image the film shares with the reports. On March 13, 1997 thousands of people across Arizona watched a V-shaped formation of lights, and some described a single dark object the width of several football fields passing slowly over Phoenix and blotting out stars; the Phoenix Lights remain the largest mass sighting in American history and were never resolved to everyone's satisfaction, the Air Force attributing the later lights to flares. Belgium's 1989 wave, the Hudson Valley boomerang of the 1980s and the 2024 New Jersey drone reports follow the same pattern: an object over a populated area, hundreds of witnesses, and no landing. District 9 asks what would happen if one of them stayed.

The aliens themselves belong to a smaller tradition. Insect-like beings appear in the abduction literature as the Mantis type, tall, calm and in charge; the film's workers are that type with the authority removed and the hunger added. Wikus's transformation, meanwhile, is the hybrid program in reverse, a human becoming alien by contamination rather than an alien breeding humans by design, and the film's MNU scientists treat him exactly as the abduction narratives say the aliens treat us: as a specimen whose body is worth more than his consent.
