They Live is a 1988 science-fiction film written (under a pseudonym) and directed by John Carpenter. In the movie, a drifter (the character is never named but Roddy Piper is credited as Nada) finds himself in Los Angeles looking like many in the country for work. Upon landing a job at a construction site, Nada befriends another worker who takes him to a shanty camp site for the homeless. After the camp’s shifty organizers run from a police raid, Nada's curiosity leads him to some sunglasses. When he puts on the glasses, he discovers the secret truth behind the upper echelon of society. The film's cast includes Roddy Piper, Keith David, Meg Foster, George 'Buck' Flower, Peter Jason, Raymond St. Jacques, and Sy Richardson, in addition to Larry Franco, one of the film's producers.
