Invasion of the Body Snatchers (1956)

Despite the purportedly apolitical intentions of its author, Jack Finney’s 1954 novel The Body Snatchers is, in many respects, a time capsule of the myriad concerns running riot across America amidst its release: rampant McCarthyism, Red Scare paranoia, the aftershocks of a post-war world.

People were as much afraid of each other as they were of the increasingly uncertain future, and so readers across the country took quick hold of Finney’s chilling story of an alien force infiltrating and replacing the inhabitants of a picturesque Smalltown, USA. Despite having received multiple adaptations over subsequent decades, none have come close to capturing the book’s overwhelming momentum and palpable dfread as effectively as the first, released in 1956 under the name Invasion of the Body Snatchers.

Having followed the story’s original serial publication in Collier Magazine, producer Walter Wanger purchased the screen rights and quickly set to work in putting together the film’s creative team. On writing duty, author Daniel Mainwaring, a pulp mystery novelist who had transitioned to screenwriting after successfully translating several of his works to the big screen, namely the 1947 noir classic Out of the Past. Don Siegel was tapped to direct after having worked with Wanger on Riot on Cell Block 11, a surprise hit that had resuscitated the latter’s career and made the former an in-demand talent. All three were enthusiastic about the adaptation’s potential, both to be a box office hit and a creatively satisfying way to explore their shared anxieties at the country’s turn towards insular paranoia and government overreach.

The film opens on a beleaguered Dr. Miles Bennell (Kevin McCarthy) being dragged through the halls of a psychiatric hospital, pleading for the staff to heed his warnings of an impending threat. After gaining audience with a local psychiatrist, he recalls the remarkable events of the last several days hoping to convince someone, anyone to believe him. His story begins with his return home to Santa Mira, CA, called back from a medical conference at the behest of his nurse, Sally, who tells him that several of his patients have requested his immediate attention. At first blush, the town seems just as he left it, but ominous signs of some unspoken change accumulate in the periphery: the most successful produce stand in the area is suddenly closed down; a typically loving child flees his mother and insists she isn’t the same; the hot spot restaurant has slowed down so much, they’ve had to fire the jazz band. Despite having only been gone for a few days, Bennell has decidedly not returned to the same Santa Mira that he left behind.

These accumulating oddities soon bleed to the fore as he meets with his patients. First, his old  high school sweetheart, Becky Driscoll, (Dana Wynter) arrives and asks for help with her cousin, Wilma. When they go to meet her, she divulges the “delusion” that’s been plaguing her: her father is not her father but an imposter, able to perfectly mimic his behaviors but incapable of imbuing them with any true feeling.  Shortly afterwards, Bennell receives an urgent call from his friend Jack requesting he come straight away. With Becky alongside, they head over and are met outside by Jack and his wife Teddy, both clearly shaken up. Before they go inside, Jack ominously asks Miles to “forget [he’s] a doctor for a while.” Alarmed but intrigued, Miles enters the house and sees an impossible thing laid out on the pool table: a seemingly lifeless body that looks suspiciously like Jack. Its features are underdeveloped, it lacks fingerprints, it has no pulse, and yet everyone is acutely aware that this thing looks like Jack, and that whatever it is, constitutes a threat to their very existence.

Scientifically minded as he is, Miles asks Jack and his wife Teddy to keep an eye on the body overnight. Exhausted, they fall asleep, and Teddy wakes up to a series of terrifying revelations: that the body is able to mirror any physical characteristics of its intended host, up to including cuts and bruises; that falling asleep near a double initiates its awakening; that threat of the Pod People could already be further underway than they thought. The invasion was meant to be imperceptible even to its closest victims, which makes its uncanny efficacy all the more terrifying for those aware of its existence.

After this, the illusion of the town’s facade tries to reassert itself onto Miles and convince him that nothing he’s seen or experienced exists outside the realm of explanation. Nearly every person who mentioned even the mildest distrust in their neighbors or loved ones reaches out to apologize for having bothered him in the first place, and the body in Jack’s house is “found” in a burning pile of hay outside of town with melted features and destroyed fingerprints. The pileup of logical excuses nearly convinces Miles that all is well, that he may too be falling victim to impossible delusions. Whatever solace mustered from this assault of reason is decimated that evening when Miles discovers a pack of plant-like pods hidden in his backyard greenhouse, each sprouting a gooey, amorphous mess that gradually takes the shape of its chosen host, evolving from bubbly mass to wax figure likeness in a matter of moments. In this moment, the truth becomes clear: a faction of alien lifeforms have burrowed their way into Santa Mira to subsume its citizens, annihilating individuals until all have been turned into ‘Pod People.’

What’s most striking about the invasion in this adaptation is how casual and unassuming its methodology becomes. In the ostensible safety of the suburbs, ordinary interactions become opportunities for continued assimilation through simple exploitation of trust. Patients insist they’re perfectly fine to their doctors after voicing serious concerns; colleagues hand-wave odd behaviors and concerns away like cigarette smoke; gas station attendants “check the trunk” and stuffing pods inside. Despite the charming white-picket fence facade, Santa Mira is a breeding ground of distrust and paranoia where every childhood friend could be a threat, every smile a sinister betrayal.

The few survivors do their best to hold out against the threat – Miles and Becky hide in his office, Jack and Teddy take a car to the next town over to get help – and find their efforts to be utterly futile, resistance having been accounted for by all those who have already succumbed. Even as Miles and Becky attempt to escape on foot, a brief separation leads to Becky falling asleep and, thus, falling prey to a pod lying in wait, ready to possess her personality and manipulate Miles to his own fate. Chased by his false love and the rushing crowds of his former friends and neighbors, he flees to a nearby highway and attempts to flag down the passing cars. Instead of following him further, the Pod People wait back, insisting “no one will believe him.” And as driver after driver proves their words true and avoids Miles, even ridicules him, the impassioned pleas for belief grow more and more desperate, leading to the film’s most iconic moment: Miles staring directly at the camera, at the audience, screaming “You’re next! You’re next!”

This strikingly bleak ending constituted an already significant divergence from the source novel, wherein Miles and the still-human Becky manage to escape the Pod People and send the unborn pods back into space, and producers were put off by the comparatively downbeat send-off to their ostensible crowd-pleaser. Thus, despite significant reluctance on his part, Siegel ultimately relented to pressure from Wanger to add on the adaptation’s other greatest change: a frame story set after Miles’s descent into madness with a happier conclusion. In it, Miles successfully convinces the psychiatrist and, by extension, the authorities of the Pod People’s existence, leading to a fade to black as Bennell listens to the military prepare to exterminate the pending threat. This frustrating thematic backtracking -- sacrificing total structural and societal paranoia for an unearned optimism in the systems of human order – remains the film’s most glaring blemish, though some fans have since removed the added material and reinstated the original vision from Siegel and Mainwaring.

Regardless of the editorial missteps, Invasion of the Body Snatchers quickly rose into the canon of seminal 1950s science-fiction films and remains a beloved classic for filmmakers and audiences alike. Few films – even the celebrated remakes from 1978 and 1993 – have been able to match its propulsive intensity and barbed social commentary, and its continued relevance across the years has only proven the accuracy of its sharp skepticism of American excellence. Back in 1956, rampant xenophobia and state-influenced anxiety wreaked havoc across the country, dividing neighbor against neighbor in a vicious cycle of perpetual distrust; 70 years later, the age-old adage still proves unfortunately true: the more things change, the more things stay the same.
