This unforgettable film might just be the best sci-fi movie ever made. Here’s why

Two men look fearful in Invasion of the Body Snatchers.

The most iconic image of Donald Sutherland’s career is a spoiler. To describe it would risk giving away more than the uninitiated might want to know about Invasion of the Body Snatchers, Philip Kaufman’s 1978 adaptation of the Jack Finney novel about extraterrestrial imposters out to replace humanity with emotionless doubles. But you know the image. You’ve almost certainly seen it used as a meme sometime over the last couple of decades — or maybe the last couple of weeks, in response to the actor’s death in June. For those who have watched the movie, there’s always been some cognitive dissonance to seeing that shot transformed into internet joke currency. It is, after all, one of the most blood-curdling images in all of cinema: the look of hope shriveling away, of the future disappearing into a screaming black hole.

It’s a tad ironic that Sutherland might be best remembered for such a grotesquely outsized expression, such a monstrous moment. He was one of Hollywood’s most subtle performers, a New Hollywood legend who often underplayed what was going on inside his characters’ hearts and heads. But his work in Invasion of the Body Snatchers is richer than its final note. As Matthew Bennell, a San Francisco health inspector who slowly becomes aware of a hostile alien takeover in progress, Sutherland offers a vast range of feelings. Arrogance, good humor, fear, deep romantic longing, bottomless despair: Long before he’s literally running from the pod people, Sutherland runs the emotional gamut across this peerless sci-fi nightmare of a thriller.

Kaufman’s Invasion is more than the best version of Finney’s story, which has been officially adapted four times and unofficially countless more. It’s also the ultimate paranoid thriller of the 1970s, a decade filled with movies about how someone was always watching and plotting against you. Contemporaneous thrillers like The Conversation, The Parallax View, and Three Days of the Condor refracted the mounting anxiety and disillusionment of the Watergate era. Invasion takes those bad vibes to their logical endpoint. Sleeping with one eye open isn’t enough, it says. You can’t go to sleep at all. And if the film’s more literally down-to-Earth Hollywood cousins captured a growing distrust in our institutions, Kaufman went much further in declaring that you literally couldn’t trust anyone. Your closest friends, your nearest and dearest — they could all be in on it.

The first adaptation of The Body Snatchers, the Don Siegel version from 1956, arrived during the Red Scare, and has been alternately read as a warning against communism and a warning against the communist witch hunts in Washington and Hollywood. Either way, conformism was the enemy. Kaufman, working from a brilliant screenplay by W.D. Richter, rewires the allegory for the anxieties of a new era. The movie does not belabor its metaphor — the Body Snatchers are an existential threat first and foremost — but it’s easy to see a cultural sea change in the biological terror spreading across a hapless Bay Area. This Invasion exists at the moment when a nation of Baby Boomers were growing out of their anti-authority stances and fully buying into Me Generation priorities. We see that in the inciting incident of the film, the way Matthew’s friend and co-worker Elizabeth (Brooke Adams) no longer recognizes her husband. Like hippies becoming yuppies overnight, he’s been replaced.

While the original Invasion left the actual body snatching to the imagination, Kaufman’s makes it grotesquely explicit. The special effects are remarkable in their disgusting tactile intricacy: When, around the midway point, the pods in Matthew’s garden open, spilling squealing, gestating quasi-humans, it’s as if we’re witnessing the birth of the practical effects renaissance of the 1980s. (Was this the seed of Rob Bottin’s similarly jaw-dropping depiction of shapeshifting alien life in The Thing a few years later?) Kaufman also hands his invaders that inhuman siren, the chilling atonal shriek the snatched emit when they’ve spotted the un-snatched. Fifteen years later, Abel Ferrara would preserve that sonic effect for his own Body Snatchers remake.

The creature-feature aspects are nifty and creepy, but the real power of Invasion of the Body Snatchers is in the realization of the characters’ fears: Just because you’re paranoid doesn’t mean the pod people aren’t really after you. The first hour of the movie throbs like a quickening pulse, as the evidence of sinister machinations mounts. More unnerving than those glistening alien bodies are scenes like the one where Sutherland’s inspector talks with a dry cleaner convinced that his wife isn’t really his wife anymore. “I keep seeing these people, all recognizing each other,” Elizabeth says. “Something’s passing between them, some secret.” The thing about Body Snatchers as a premise is that it’s endlessly malleable, interpretatively speaking (there’s a reason they’ve made so many versions), but the crux of the material is a primal fear beyond rational thought — the bone-deep terror that no one is who they claim to be. The second half of the film realizes that on a grand, nail-biting scale, as the characters try to flee a San Francisco that’s become one big, parasitic organism.

As a thriller, Invasion of the Body Snatchers is basically perfect: The arc of the plot from steadily tightening suspense to extended chase sequence has never really been matched. But like that infamous dog-man thing — a mistake of the cloning process — that scampers in to blow Matthew and Elizabeth’s cover, the film is a genetic hybrid of genres. Beneath its expert blend of body horror, H.G. Wellsian sci-fi, and conspiracy thriller, Invasion of the Body Snatchers works splendidly as a sly satire of a society hooked on self-help and New Age platitudes, as embodied by a damningly logical Leonard Nimoy. What are the pod people but malevolent life coaches, helping humanity permanently shed their messy, inconvenient emotional baggage?

And on another level still, Invasion of the Body Snatchers works as a rapturous romance. While the world is swallowed by an invasive species, Matthew and Elizabeth confess their feelings for each other, a friendship blossoming into something more on the eve of humanity’s total assimilation into a hive. Sutherland and Adams have a warm, casual chemistry that betrays the truth about their relationship before their characters dare speak it. So does the scene where Matthew finds himself incapable of destroying the nearly perfect, slumbering doppelganger of the woman he loves. Their climactic declaration of devotion is like a death rattle for mankind, beautiful and tragic.

It’s Sutherland, working at the height of his skills, who anchors Invasion of the Body Snatchers. It’s a full movie-star performance, getting the absolute most out of his shaggy ’70s sex appeal, his intelligence, his wit. More than that, he becomes a kind of ambassador for humanity’s messy worth, embodying all the qualities we stand to lose if the pod people complete their purification protocol. Therein lies the gut punch of the unforgettable ending, undiminished by a million out-of-context memes: As Donald Sutherland goes, so goes humanity.

Invasion of the Body Snatchers is currently streaming on Amzazon Prime with a MGM+ subscription, and is available to rent or purchase from the major digital services. For more of A.A. Dowd’s writing, please visit his Authory page.

The sci-fi genre is more alive and popular than ever. Just last weekend, Gareth Edwards' original blockbuster The Creator debuted in multiplexes nationwide, while more arty movies like The Beast and Poor Things premiered at the 2023 New York Film Festival to almost universal acclaim. Now more than ever, sci-fi speaks to our particular moment in time, when the rise of AI technology magnifies humankind's universal concerns about identity, aging, and mortality.

Why Jon Pertwee’s Doctor Who is the best version of the character ever
The Doctor is about to be attacked in Doctor Who.

Growing up in the '90s, Doctor Who wasn't really a thing. Following the sci-fi show's cancellation in 1989, there was a 16-year period – aside from a one-off television movie in 1996 that failed to resurge the series as a whole – where traveling through time and space in a little blue box was non-existent. And yet during this time, at the young age of six, I was first introduced to a mysterious man with a bouffant hairstyle, velvet jacket, and a thrill for adventure.

This was Jon Pertwee. The once-circus performer and Royal Navy member (who reported directly to Winston Churchill during the Second World War), before later turning to the world of acting, made his debut as the Time Lord in January 1970's Spearhead from Space. Taking on the Autons, life-sized plastic dummies animated by an alien Nestene Consciousness, it didn't take long for the 50-year-old to make his mark.
Pertwee's Doctor Who was the perfect hero to root for
Death to the Daleks, a four-part adventure with Sarah Jane (played by the wonderful Elisabeth Sladen), is one of the earliest memories from my childhood. In many ways, it's a story indicative of the show's lasting charm. We have the Doctor's greatest foe in the Daleks, one of the most loved companions in Sarah Jane, and the terrifying Exxilons that contributed to the "hiding behind the sofa" phenomenon that scared children for decades. We even have the Root, a snake-like creature whose schlocky effects answer the question of what would happen if your Dyson hoover went rogue.

This action film is one of the most popular movies on Netflix. Here’s why you should watch it
the mother reasons why you should watch netflix action movie holding a rifle

The action genre is a tried and true formula that will never cease to be popular. It's often the spectacle of watching a sole individual achieve the impossible through the sheer force of will. And while the climactic moments of these films are often miles from reality, it's the power fantasy and the jolt of adrenaline these explosive sequences often deliver that make action movies so appealing. What ultimately makes or breaks an action film are the characters at the heart of the story. We'll return time and time again to watch Tom Holland's plucky Spider-Man experience the next big upset in his web-slinging career. And let's not forget Vin Diesel's Dom Toretto and his family of specialists who seem to hold an unshakeable power over death itself.

But in Netflix's latest offering, The Mother, the breathless velocity is laced with a serious edge. Jennifer Lopez sheds her rom-com persona and assumes a tough, surprisingly effective action-hero persona. As an expert assassin, Lopez must protect the child she gave up years ago from being killed by former associates who want both of them dead. The Mother is a lean, often brutal action movie, one that has proven to be a hit with audiences as it's one of the most popular movies on Netflix. Here's why you should watch it right now.
