District 9 (2009)

Neill Blomkamp anchors high-concept extraterrestrial arrival in the gritty, diesel-scented shantytowns of Johannesburg. Commercial security contractor Multi-National United oversees the encampments with heavy earthmoving diggers, boxy cathode-ray surveillance units, and mechanical weapons patched into car batteries. The resulting aesthetic feels tactile and improvised, replacing clean space-age sleekness with scrap metal, grease, and raw utilitarian machinery.
