The Quiet Earth is a 1985 New Zealand post-apocalyptic science fiction film directed by Geoff Murphy and starring Bruno Lawrence, Alison Routledge and Peter Smith as three survivors of a cataclysmic disaster. It is loosely based on the 1981 science fiction novel of the same name by Craig Harrison. Other sources of inspiration have been suggested: the 1954 novel I Am Legend, Dawn of the Dead, and especially the 1959 film The World, the Flesh and the Devil, of which it has been called an unofficial remake.

Geoffrey Peter Murphy was a New Zealand filmmaker, producer, director, and screenwriter best known for his work during the renaissance of New Zealand cinema that began in the second half of the 1970s. His second feature Goodbye Pork Pie (1981) was the first New Zealand film to win major commercial success on its soil. Murphy directed several Hollywood features during the 1990s, before returning to New Zealand as second-unit director on The Lord of the Rings film trilogy. Murphy was also a scriptwriter, special effects technician, schoolteacher and trumpet player at different times. He was married to Merata Mita, a film director, actor, writer.
