Invasion of the Body Snatchers (1956)

Miles Bennell, a GP in the small Californian town of Santa Mira, returns from an out-of-town meeting to find himself inundated with calls from locals insisting that members of their family are not the same people any more or have changed in some way. Believing this to be some type of mass hallucination, he refers them to a psychiatrist. He meets his old girlfriend Becky Driscoll and starts seeing her again. They are interrupted at dinner by mystery writer Jack Belicec who takes them to see a body found on his pool table, one mysteriously lacking any type of distinguishing marks, even fingerprints. As Jack sleeps, his wife sees the body form into a likeness of Jack, even down to a recent cut on its hand. Miles finds a similar body forming in Becky’s basement. But when they try to show the bodies to the police they have vanished and they think in the rationale of daylight that they have succumbed to the mass delusion too. But as night falls again they find pods in Miles’s glass house. When they try to run they find everywhere that the townspeople have turned into hostile, emotionless pod people trying to stop them.
