Invasion of the Body Snatchers, 1978. A science fiction horror. Directed by Philip Kaufman. Starring Donald Sutherland, Brooke Adams, Veronica Cartwright, Jeff Goldblum and Leonard Nimoy.
The film is a remake of the 1956 film of the same name, which was based on the novel The Body Snatchers by Jack Finney. The plot involves a San Francisco health inspector and his colleague who discover humans are being replaced by duplicate aliens who appear to be perfect copies of the persons replaced, but devoid of any human emotion, who attempt to install a tightly organized, conformist society.
In deep space, a race of gelatinous creatures abandon their dying world. Pushed through space by solar wind, they make their way to Earth and land in San Francisco. Some fall on plant leaves, assimilating them and forming small pods with pink flowers. Elizabeth, an employee at the San Francisco health department, is one of several people who bring flowers home. The next morning, Elizabeth’s boyfriend, Geoffrey, suddenly becomes distant, and she senses that something is wrong. Her colleague, health inspector Matthew suggests that she see his friend, a psychiatrist, Dr. Kibner, who suggests that Elizabeth wants to believe that Geoffrey has changed because she is looking for an excuse to get out of their relationship.
Meanwhile, Matthew’s friend Jack, a struggling writer who owns a bathhouse with his wife Nancy, discovers a deformed body on one of the beds and calls Matthew to investigate. Noticing that the body (which is adult sized but lacks distinguishing characteristics) bears a slight resemblance to Jack, Matthew breaks into Elizabeth’s home and finds a semi-formed double of her in the bedroom garden. He is able to get the sleeping Elizabeth to safety, but the duplicate body has disappeared by the time he returns with the police.
Matthew realizes that what is happening is extraterrestrial, and that people are being replaced by copies while they sleep. Matthew calls several state and federal agencies, but they all tell him not to worry. In addition, people who had earlier claimed that their loved ones had changed seem to have been converted as well, including (unbeknownst to him) Dr. Kibner.
That night, Matthew and his friends are nearly duplicated by the pods while they sleep. The pod people try to raid Matthew’s house, but he and his friends are able to escape. During this, they discover that the pod people emit a shrill scream once they learn someone is still human among them.
"They were right, it’s painless. It’s good. Come. Sleep."
