''Invasion of the Body Snatchers'' is a series of SciFiHorror films revolving around an invasion of "pod people" who infiltrate the Earth by replacing humans with duplicates. Originally a 1956 film ([[AdaptationDisplacement which was itself based on a novel]]), the concept seems to resonate particularly well with new generations. It has been remade no less than three times since with various changes to the plot.

The films are:

* ''Film/{{Invasion of the Body Snatchers|1956}}'' (1956)
* ''Film/{{Invasion of the Body Snatchers|1978}}'' (1978)
* ''Film/BodySnatchers'' (1993)
* ''The Invasion'' (2007)

The original film also provided inspiration for the 2005 ABC series ''{{Series/Invasion}}''.

Not to be confused with the horror movie Film/TheBodySnatcher.

!!These films include examples of:

!!!All versions

* AlienInvasion: [[CaptainObvious Sounds like it.]]
* AssimilationPlot: All of them. [[DiscussedTrope Discussed]] in the 1978 version.
* BittersweetEnding: [[spoiler: The 1956]] version, along with the [[spoiler: 1993 and 2007 ones]]
* CleanupCrew: The garbage men in the 1978 movie are implied to be this for when the duplicates fail to develop. Garbage trucks are also glimpsed in the '93 version.
* CassandraTruth
* EvilTwin: Kinda. The pod people are exact physical and mental duplicates of the originals, but are coldly logical and driven to ensure their species survives by converted all of humanity.
* InfantImmortality: Averted multiple times in different versions, as children are either shown having already been replaced or about to be. One notable example comes from [[spoiler:the '93 version with Marti's younger brother]].
* InformedAttribute: The supposedly emotionless pod people aren't always so emotionless.
** In the final scene, Matthew sees a group of school children who are behaving just like regular school children.
** Forest Whitaker's co-workers are angry or giggling over how they can't be beat.
* InvisibleAliens: The pod people, technically. Their original alien forms are protoplasmic -- they're sapient germs in the 2007 version -- and they take over people by absorbing their memories, forming perfect replicas of the bodies, and destroying the originals, so they seamlessly step into the original's life.
* KillAllHumans: And replace them with lookalikes.
* NeverSleepAgain: The Pod People can only replace you when you sleep.
* ReplicantSnatching: The entire premise of the series.
* StepfordSuburbia: What happens to society as the pod people take over. There's no fighting, fuss, crime or problems... but there's no laughter, smiling, or human warmth, either. The pod people, once in control, are like zombies of the old-school Voodoo style: fleshy automatons that just robotically do their tasks without any individual thought or drives.
* VampiricDraining: While not explicit, it is implied that in order to copy a living being, the Pods take something fundamental and necessary from the original as after duplication, the original disintegrates into dust.
* WeAreEverywhere: How the films work; because the pods show up all over, by the time anyone has figured out what's going on, there are pod people in all sorts of positions, from lowly street people to police officers, phone operators, doctors, psychiatrists, everywhere. And of course the pods in authority can get even ''more'' people converted before they realise what's happening, so their numbers just keep growing, and growing...
* TwistEnding: The 1978 ([[spoiler:[[AndThenJohnWasAZombie Matthew was transformed]]]]) and 2007 ([[spoiler:the alien virus is curable]]) remakes.

!!!2007 version

''The Invasion'' (2007), another GenderFlip version with Creator/NicoleKidman. Amongst many other changes, they dropped the idea of alien replacements entirely, going for a simple [[spoiler:and reversible]] version of TheVirus. It also worked in TheWarOnTerror and, with it, questions regarding TheEvilsOfFreeWill.

* CoveredInGunge: The 2007 version.
* CreepyChild: [[spoiler:Two of Oliver's friends]] in the 2007 version. [[spoiler:Both were infected by the virus.]]
* RemakeCameo: Veronica Cartwright, who was in the 1978 film, has a small role in the 2007 film.
* PuppeteerParasite: The Pod People in the 2007 version are changed to this, being microbial organisms rather than the duplicating plant-things of earlier films.
* TheVirus: The 2007 version. It still causes a pod people [[TransformationTrauma transformation]] when the victim sleeps, though.
