Invasion of the Body Snatchers is a 1956 American science fiction horror film produced by Walter Wanger, directed by Don Siegel, and starring Kevin McCarthy and Dana Wynter. The black-and-white film, shot in Superscope and in the film noir style. Daniel Mainwaring adapted the screenplay from Jack Finney's 1954 science fiction novel The Body Snatchers. The film was released by Allied Artists Pictures as a double feature with the British science fiction film The Atomic Man (and in some markets with Indestructible Man).

The film's storyline concerns an extraterrestrial invasion that begins in the fictional California town of Santa Mira. Alien plant spores have fallen from space and grown into large seed pods, each one capable of producing a visually identical copy of a human. As each pod reaches full development, it assimilates the physical traits, memories, and personalities of each sleeping person placed near it until only the replacement is left; these duplicates, however, are devoid of all human emotion. Little by little, a local doctor uncovers this "quiet" invasion and attempts to stop it.
