There are monsters we expect to fear.
Vampires emerge from the darkness.
Werewolves howl beneath a full moon.
Sharks circle unseen beneath the water’s surface.
But every now and then, horror asks us to fear something so ordinary that we barely notice it.
The ground beneath our feet.
When Jeff Lieberman’s Squirm slithered into cinemas in 1976, audiences were treated to what sounded like one of the decade’s more outrageous premises: a violent electrical storm sends high-voltage power lines crashing into the rain-soaked earth, transforming an ordinary population of worms into ravenous flesh-eating predators.
It is exactly the sort of wonderfully absurd concept that could only have emerged during the golden age of 1970s creature features.
Yet beneath its B-movie exterior lies something surprisingly revealing about the decade that produced it.
When Nature Turned Against Us
The 1970s marked a turning point in horror cinema.
Gone were the Gothic castles and supernatural curses that had dominated previous generations. Instead, filmmakers increasingly looked towards the natural world as the source of humanity’s nightmares.
The decade was shaped by growing environmental awareness. Industrial pollution, pesticide use, the oil crisis and fears surrounding humanity’s exploitation of the planet entered public consciousness with unprecedented urgency. The first Earth Day had been celebrated only a few years earlier, while environmental activism was steadily becoming part of mainstream conversation.
Cinema responded accordingly.
Rather than presenting nature as something beautiful or indifferent, horror increasingly imagined it fighting back.
Suddenly frogs became deadly.
Ants organised themselves into terrifying colonies.
Spiders descended in overwhelming numbers.
Even rabbits—perhaps cinema’s least threatening creatures—were transformed into monstrous killers.
In that context, Squirm wasn’t an isolated oddity.
It was part of a wider movement that suggested humanity had disrupted the natural order for so long that nature itself had begun to retaliate.
The enemy was no longer a vampire.
It was the ecosystem.
The Horror Beneath Our Feet
What distinguishes Squirm from many of its contemporaries is the simplicity of its central fear.
Most monster movies encourage audiences to look outward.
Towards the sea.
Towards the forest.
Towards the night sky.
Lieberman asks us to look down.
It is a remarkably effective psychological shift.
Worms are among the least glamorous creatures imaginable. They are silent, blind and usually hidden beneath the earth. We rarely think about them at all.
Until Squirm.
By transforming the soil itself into a source of danger, Lieberman quietly undermines one of our most basic assumptions—that the ground is safe.
There is something deeply unsettling about that idea.
The earth, after all, is supposed to be stable. It is where we build our homes, grow our food and seek shelter from the unknown.
Squirm imagines that sanctuary becoming hostile.
The monster is no longer lurking somewhere beyond civilisation.
It has been beneath civilisation all along.
B-Movie Sincerity
Viewed today, Squirm is undeniably a product of its time.
Its performances occasionally drift towards melodrama.
Some of the dialogue invites unintentional laughter.
Certain effects reveal the limitations of a modest budget.
Yet those very imperfections are part of its enduring charm.
Lieberman never approaches the material with irony.
He believes in the premise wholeheartedly.
That sincerity proves infectious.
Modern creature features often hide behind self-awareness, acknowledging their absurdity before audiences have the opportunity to question it.
Squirm refuses to apologise.
It commits completely to the idea that ordinary worms can become instruments of unimaginable terror.
Oddly enough…
That commitment makes the film easier to embrace.
The Legacy of Eco-Horror
While Squirm may never receive the same critical recognition as some of horror’s more celebrated classics, its place within the evolution of eco-horror deserves acknowledgement.
Alongside films such as Frogs, Night of the Lepus, Empire of the Ants, Kingdom of the Spiders, Australia’s Long Weekend and Prophecy, it helped define a period in which nature ceased to be a backdrop for horror.
It became horror itself.
Many contemporary environmental thrillers continue to explore similar anxieties, albeit through different metaphors.
Climate change.
Pandemics.
Ecological collapse.
The specifics may have evolved, but the underlying fear remains remarkably familiar.
Humanity’s greatest threat may ultimately be the world we have reshaped.
The Prognosis:
Squirm is far from a flawless film.
Its premise borders on the ridiculous, its execution occasionally stumbles and it lacks the polish of many better-known horror classics from the decade.
Yet dismissing it as nothing more than a killer worm movie overlooks its significance.
Jeff Lieberman captured a moment when horror cinema stopped asking audiences to fear distant monsters and instead encouraged them to question their relationship with the natural world itself.
Perhaps that is why the film continues to burrow beneath the surface of horror history.
Not because giant carnivorous worms are especially believable…
But because Squirm reminds us that the most effective creature features are rarely about the creatures.
They’re about the fears waiting just beneath the surface.
And in 1976, few fears felt more immediate than the possibility that nature had finally decided to fight back.
