The Body Snatchers is a science fiction horror novel by American writer Jack Finney, originally serialized in Collier's magazine in November–December 1954 and published in book form the following year.
The novel describes the town of Mill Valley, in California's Marin County, being invaded by seeds that have drifted to Earth from space. The seeds, grown from plantlike pods, replace sleeping people with perfect physical duplicates with all the same knowledge, memories, scars, etc. but are incapable of human emotion or feeling. The human victims disappear forever.
The duplicates live only five years and cannot sexually reproduce; consequently, if unstopped, they will quickly turn Earth into a dead planet and move on to the next world. One of the duplicate invaders claims this is what humans do – use up resources, wipe out indigenous populations, and destroy ecosystems in the name of survival.
The novel has been adapted for the screen four times; the first film, Invasion of the Body Snatchers in 1956, the second in 1978, the third in 1993, and the fourth in 2007. It was also the basis of the 1998 movie The Faculty and the 2019 movie Assimilate.
Unlike the first three film adaptations, which elected for darker, far more dystopian narratives (particularly the 1978 version), the novel contains an optimistic ending, with the aliens voluntarily vacating after deciding that they cannot tolerate the type of resistance they see in the main characters and leaving behind a small population of duplicates who are all hunted and killed shortly after.
In 1967, Damon Knight criticized the novel's scientific incoherence:[1]
The seed pods, says Finney, drifted across interstellar space to Earth, propelled by light pressure. This echoes a familiar notion, the spore theoryofArrhenius. But the spores referred to are among the smallest living things – small enough to be knocked around by hydrogen molecules...In confusing these minute particles with three-foot seed pods, Finney invalidates his whole argument – and makes ludicrous nonsense of the final scene in which the pods, defeated, float up into the sky to hunt another planet.
Horrifyingly depicts the invasion of a small town by interstellar spores that duplicate human beings, reducing them to dust in the process; the menacing spore-people who remain symbolize, it has been argued, the loss of freedom in contemporary society. Jack Finney's further books are slickly told but less involving.
Galaxy reviewer Groff Conklin faulted the original edition, declaring that "Too many s-f novels lack outstanding originality, but this one lacks it to an outstanding degree."[3]F&SF reviewer Anthony Boucher found it to be "intensely readable and unpredictably ingenious" despite noticeable inconsistencies and its sometimes lack of scientific accuracy.[4]Astounding Science-Fiction reviewer P. Schuyler Miller reported that, once Finney sets out his premise, the novel becomes "a straight chase yarn, with several nice gimmicks and a not entirely convincing denouement."[5]
