Invasion of the Body Snatchers is a 1956 science fiction film. It stars Kevin McCarthy, Dana Wynter, King Donovan and Carolyn Jones and is based on the novel The Body Snatchers by Jack Finney (originally serialized in Colliers Magazine in 1954). The film has been remade three times and has been selected for preservation in the United States National Film Registry. A somewhat similar plot appeared in the 1958 film, I Married A Monster From Outer Space.

The screenplay was adapted from Finney's novel by Daniel Mainwaring (who also wrote the film noir classic Out of the Past), along with an uncredited Richard Collins. It was directed by Don Siegel, who went on to make The Killers and Dirty Harry.

Invasion of the Body Snatchers is a 1978 science fiction film based on the novel The Body Snatchers by Jack Finney. It is a remake of the 1956 film of the same name. The original music score was composed by Danny Zeitlin.

This remake starred Donald Sutherland, Brooke Adams, Jeff Goldblum, Veronica Cartwright, Leonard Nimoy and Jerry Walter. It was adapted by W. D. Richter and directed by Philip Kaufman. Unlike many remakes, it met a generally favorable critical response and performed very well at the box office, earning nearly $25 million in the United States, well over its budget of $3.5 million; The New Yorker's Pauline Kael, who said "it may be the best film of its kind ever made," was a particular fan.http://www.nybooks.com/articles/1959

Dr Miles Bennel returns his small town practice to find several of his patients suffering the paranoid delusion that their friends or relatives are impostors. He is initially sceptical, especially when the alleged dopplegangers are able to answer detailed questions about their victim's life, but he is eventually persuaded that something odd has happened, and determines to find out what. This film can be seen as a paranoid 1950s warning against those Damn Commies, or conversely as a metaphor for the tyranny of McCarthy-ism (or the totalitarian system of Your Choice) and has a pro- and epilogue forced upon Siegel by the studio to "lighten the tone".

He returned to his small town the previous Thursday have been called back from a medical conference by his nurse who was being flooded with patients. He arrives to find that most have canceled their appointments, but the few cases he does have all have the same story: someone close to them is acting strangely as if they had been replaced. Consulting some of his colleagues, he finds that these types of reports have been coming in all week and they conclude it must be some type of mass hysteria. However when his friends Jack and Teddy Belicec show him a partly formed body they have uncovered in their home, he begins to realize that there may be some truth to the wild stories he has been hearing.

The first remake of the paranoid infiltration classic moves the setting for the invasion from a small town to the city of San Fransisco and starts as Matthew Bennell notices that several of his friends are complaining that their close relatives are in some way different. When questioned later they themselves seem changed as they deny everything or make lame excuses. As the invaders increase in number they become more open and Bennell, who has by now witnessed an attempted "replacement" realises that he and his friends must escape or suffer the same fate. But who can he trust to help him and who has already been snatched? Written by Mark Thompson
