One Actor Played All The Aliens In District 9
Sony Pictures Releasing and YouTube/D/P30: The Oral History of Hollywood
In an interview with Gizmodo, director Neill Blomkamp revealed that one actor played all the aliens in District 9. Jason Cope hopped from set to set in motion capture sensors to play multiple roles. During the eviction scene, Cope and fellow actor Sharlto Copely improvised all dialogue.
During an interview with Love-It-Loud, Cope said that he and Sharlto filled in wherever they had to–helping the wardrobe, acting as soldiers, and directing the art department. When asked how many characters he ended up playing, Cope said, “I have no idea. It must be close to fifty, perhaps more.”
