Movie Monday: Primate, Killer Apes, and the Stories We Tell About Animals

Welcome back to Movie Monday.

This is only the second entry in the series, but the intention is already clear: this isn’t about quick reviews or ranking creature features by body count. It’s about looking at animal-led horror films through a wider lens… asking what they borrow from reality, what they distort, and what impact those stories have beyond the screen.

This week, the focus is a brand new film – Primate, directed by Johannes Roberts. It’s a deliberately confrontational piece of horror: graphic, tense, and unflinching in its depiction of violence. On the surface, it fits comfortably within the long tradition of “killer animal” cinema. But beneath that familiar framework, I think Primate is doing something more thoughtful, and more troubling.

Intelligence as Horror, Not Gimmick

There is a particular kind of discomfort that lingers after watching Primate. Not the fleeting unease of jump scares or gore, but something quieter and more persistent. A sense that what you’ve just watched isn’t entirely fictional and that the true horror sits uncomfortably close to reality.

The film centres on a chimpanzee capable of communicating through sign language. When the animal contracts rabies, its behaviour becomes violently unstable. What makes this premise effective is not the novelty of intelligence, but how seriously the film treats it.

The chimp’s cognition is not there to make it sympathetic, nor to humanise it for easy emotional manipulation. Instead, intelligence becomes an amplifier. The violence is more disturbing precisely because the audience understands this is not a mindless creature lashing out, but a thinking being whose perception of the world has been catastrophically altered.

Rabies matters here. The film resists framing the chimp as evil, possessed, or monstrous by nature. This is disease, not malice. Pathology, not punishment. That distinction shifts the moral weight of the story away from the animal and back toward the conditions that made such an outcome possible in the first place.

The Horror Isn’t the Chimp

This is where Primate brushes up against an uncomfortable truth that horror cinema has often avoided.

The horror isn’t the chimp. The horror is the belief that we can safely domesticate something that was never meant to be ours.

Highly intelligent animals do not become safer through proximity to humans. If anything, intelligence increases unpredictability when an animal is denied its natural social structures, environmental cues, and physical autonomy. Familiarity does not override biology.

Viewed through this lens, Primate stops being a simple killer-ape film. It becomes a story about misplaced control and the human tendency to mistake access for understanding.

Real-world cases have already shown how fragile this illusion is. In 2009, Travis the chimp — raised in a domestic setting and long treated as a familiar presence rather than a wild animal, violently attacked a woman in his owner’s home. The incident was not the result of cruelty or neglect in any simple sense, but of a far more uncomfortable truth: a highly intelligent, powerful animal had been placed in an environment it was never designed to navigate. When something went wrong, the consequences were catastrophic.

Love did not cancel instinct. Intelligence did not equal compliance.

Primate fictionalises this reality, but it does not exaggerate it. The film’s horror grows from the same fault line: the human insistence that proximity and affection can neutralise biology.

Killer Apes and Cinematic Inheritance

Cinema has a long, complicated relationship with apes. From the earliest monster films through to modern horror, they occupy an uneasy space: strong enough to threaten us, intelligent enough to unsettle us, and similar enough to us to provoke discomfort.

Films like King Kong established a template where apes became symbols of chaos, domination, or fear of the “other”. Too often, those stories leaned on spectacle rather than context, asking audiences to fear the animal without interrogating why it was placed in conflict with humans at all.

Primate inherits that cinematic lineage, but it doesn’t fully repeat its mistakes. The chimp is dangerous, yes, but the film never lets the audience forget that the danger is engineered. Captivity, experimentation, disease, and human arrogance form the backdrop to every violent act.

The animal is not framed as a natural villain. The system surrounding it is.

Misrepresentation, Responsibility, and Modern Horror

This raises a broader question, one that modern creature features can maybe no longer avoid. Can we still make effective animal-led horror without slandering a species?

The answer may lie in perspective rather than restraint. Horror does not lose its power when animals are portrayed honestly; if anything, it becomes more unsettling. When behaviour is grounded in biology, instinct, stress, and environment, violence stops feeling arbitrary and starts feeling inevitable.

Too many older films treated animals as symbols — metaphors for chaos, punishment, or nature “striking back”. In doing so, they often stripped creatures of context, reducing complex species to simple villains. The result was fear without understanding, and spectacle without consequence.

Primate largely avoids that trap. The chimp’s actions are horrifying, but they are never divorced from cause. Captivity, experimentation, disease, and human interference form the framework within which the violence unfolds. The animal is not behaving “out of character”. It is behaving exactly as a compromised, intelligent animal might.

This is an approach I’ve deliberately taken in my own fiction. When I write from the point of view of the creature, it isn’t to humanise or excuse its actions, but to clarify them. To show how instinct, territory, stress, and survival pressures shape behaviour, and how easily human presence destabilises that balance. Horror, in this context, doesn’t come from malice. It comes from collision.

When animals are depicted honestly, the question shifts. The fear is no longer what is the creature capable of? It becomes why did we put it in this position at all?

That, perhaps, is where modern creature-feature horror finds its real responsibility, not in softening its monsters, but in telling the truth about them.

Looking Ahead

Slandering a species has consequences, as Peter Benchley discovered after the unprecedented success of Jaws.

Hot off its 50th anniversary year in 2025, Jaws offers a powerful case study in how fiction can shape fear and how those fears can ripple outward into real-world destruction. In a future Movie Monday, we’ll look at how that film and book sounded a death knell for millions of sharks in the decades that followed, and how Benchley himself later became a vocal champion for their protection.

Because stories about animals don’t end when the credits roll. They linger. And sometimes, they bite far deeper than intended.

🎬 Movie Monday: When Real Animals Became Movie Monsters

Stories have always borrowed from the natural world, sometimes consciously, sometimes not.

Movie Monday is a new, occasional series exploring where cinema, wildlife, and myth overlap: the real animals, behaviours, and biological truths hiding behind some of our most enduring screen monsters.

It sits alongside Monster Monday and Maneater Monday — different lenses on the same question: why certain creatures, real or imagined, refuse to loosen their grip on us.

We like to believe that cinema monsters are born from imagination alone… nightmares made flesh, conjured by writers staring into the dark.

But again and again, the truth is stranger.

Some of the most iconic creatures in film and fiction didn’t come from myth at all. They came from nature, from animals whose behaviours were already so efficient, alien, or unsettling that they barely needed exaggeration.

Filmmakers didn’t invent these monsters.
They recognised them.

👹 Predator: insects, instinct, and a moment at 30,000 feet

The creature in Predator is often remembered for its technology: cloaking devices, shoulder cannons, thermal vision, ritualised hunting codes.

But strip all of that away and you’re left with something far older.

During early development, legendary creature designer Stan Winston was struggling to finalise the Predator’s look. While flying with James Cameron, he talked through the problem, and it was Cameron who suggested a simple, unsettling solution: give it mandibles.

That single idea changed everything.

Designers have since acknowledged the influence of insects, particularly praying mantises, in the Predator’s face and posture. Forward-facing eyes. Mandible-like jaws. A head shaped for tracking and striking rather than expression or empathy.

Mantises already look extraterrestrial to us. They rotate their heads. They calculate distance. They dismember prey with methodical calm.

Even the creature’s voice reinforces this lineage. The distinctive clicking and chittering sounds were created by Peter Cullen, deliberately leaning into insect-like vocalisations rather than anything recognisably mammalian or humanoid.

The Predator doesn’t invent that fear.
It scales it up, arms it, and releases it into a jungle.

What remains, beneath the tech, is an apex ambush hunter — something we instinctively recognise, even if we can’t quite place why.

👽 Alien: nature’s most efficient horror machine

The creature in Alien remains one of cinema’s most disturbing designs because it feels biological. Every stage of its life cycle obeys a logic — parasitic, efficient, and utterly indifferent.

That’s because it draws from multiple real-world inspirations.

One is the deep-sea amphipod Phronima sedentaria, sometimes called the “monster in a barrel.” This tiny crustacean hollows out gelatinous animals, lives inside their emptied bodies, and uses them as both shelter and nursery. It’s parasitism turned architectura.

Then there’s the Alien’s inner jaw, eerily similar to the pharyngeal jaws of moray eels, a second set of jaws that shoot forward from the throat to drag prey deeper inside the body. Watching one in action feels like watching a design error, until you realise how brutally effective it is.

The acid blood? That has uncomfortable echoes of the bombardier beetle, which stores volatile chemicals in separate chambers and mixes them only when threatened, releasing a boiling, corrosive spray with startling precision.

Even the facehugger carries a lineage. Its spidery grip, tail wrap, and underside anatomy closely resemble the ancient horseshoe crab, a creature so old it predates dinosaurs, and so alien it barely seems terrestrial at all.

Alien isn’t fantasy biology.
It’s biology… refined.

🧛 Dracula: when bats became monsters

While working on Dracula, Bram Stoker encountered a New York newspaper clipping describing vampire bats – small, blood-feeding mammals that had been newly “discovered” by Western science and already framed as unnatural horrors.

They didn’t drain victims dry, as legend claimed. But they did feed silently, painlessly, and in the dark. They made small incisions, returned night after night, and relied on anticoagulants to keep blood flowing.

That was enough.

Stoker fused this real behaviour with Eastern European folklore, and suddenly vampirism became biological as well as supernatural. Dracula wasn’t just cursed — he fed, adapted, survived.

Once again, fear took root because it had a foothold in reality.

🦈 Jaws: the predator we misunderstood

Jaws didn’t invent the fear of sharks, but it magnified it catastrophically.

The great white shark is a powerful apex predator, yes. But it is also cautious, energy-efficient, and rarely interested in humans. Most bites are investigative, unfortunate cases of mistaken identity.

In Jaws, however, the shark becomes something else entirely: territorial, vengeful, strategic. It stalks specific individuals. It understands fear.

The exaggeration worked, all too well. The film permanently altered public perception of sharks, contributing to fear-driven culls and a legacy of misunderstanding that conservationists are still trying to undo.

It’s a reminder that when cinema borrows from nature, it doesn’t always give back responsibly. I am working on my own shark-based story, and will have to try and be as respectful as I can with the subject matter.

🍄 The Last of Us and the zombie ant fungus

The monsters of The Last of Us, from the video game and then brought chillingly to life in the HBO series, feel plausible because they already exist.

Ophiocordyceps unilateralis infects carpenter ants across tropical forests. Once inside, the fungus alters the ant’s behaviour, compelling it to climb vegetation and clamp down with its mandibles.

Then it kills the host.

A fungal stalk erupts from the ant’s head, releasing spores onto the forest floor below, perfectly positioned to infect the next generation.

There’s no rage. No hunger. No malice.

Just control.

The horror of The Last of Us lies not in the fantasy of zombies, but in the quiet realisation that free will is not as secure as we think.

🪱 Tremors: ambush predators beneath our feet

The graboids in Tremors feel absurd, until you consider how many real animals hunt exactly this way.

Trapdoor spiders wait motionless beneath the soil, sensing vibrations before exploding upward to seize prey. Bobbit worms bury themselves in sand, striking with astonishing speed, sometimes slicing fish clean in half.

Both rely on:

  • Vibration detection
  • Ambush rather than pursuit
  • Minimal exposure

The genius of Tremors is that it makes the ground itself hostile. The monsters don’t chase — they wait.

Which, biologically speaking, is often far more efficient.

🟢 Slime moulds and The Blob

Slime moulds aren’t fungi. They aren’t animals. They’re something else entirely, capable of learning, problem-solving, and forming efficient networks without a brain.

They flow. They engulf. They adapt.

The creature in The Blob exaggerates this into apocalyptic form, but the unease is justified. Slime moulds already challenge our definitions of intelligence and individuality.

They don’t hunt.
They spread.

Why these monsters endure

The most effective movie monsters don’t break the rules of nature.

They obey them too well.

They feed, reproduce, adapt, and survive. They don’t hate us, they don’t even notice us! And that’s what makes them frightening.

Nature doesn’t need motivation.
Only opportunity.
