They Live is a 1988 American satirical science fiction action horror film written and directed by John Carpenter. The film stars Roddy Piper, Keith David and Meg Foster. It follows a nameless drifter (called "John Nada" in the credits), who discovers 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.
At release it was number one in the box office, but sales soon suffered, though the film was nominated for two Saturn Awards. The film has since garnered a large cult following. The film has had a lasting impact on street art, particularly that of Shepard Fairey, quotations have entered the popular culture, and it makes appearances on all-time lists for best fight scenes.
