They Live is a 1988 American science fiction horror film written and directed by John Carpenter. The film stars Roddy Piper, Keith David, and Meg Foster. It follows an unnamed drifter (referred to as “John Nada” in the film’s credits) who discovers that the ruling class are in fact aliens concealing their appearance and manipulating people to spend money, breed, and accept the status quo with subliminal messages in mass media. It is based on the 1963 short story, “Eight O’Clock in the Morning” by Ray Nelson.

At release it was number one in the box office, but sales soon suffered, though the film was nominated for two Saturn Awards. They Live has since become a cult film. The film has had a lasting impact on street art, particularly that of Shepard Fairey; its quotations have entered the popular culture, and it makes appearances on all-time lists for best fight scenes.
