Monkeys are usually cute, right? A little mischievous, maybe, but nothing to lose sleep over. Well, Hollywood had other plans. Over the years, filmmakers have taken these banana-loving furballs and turned them into nightmare fuel. Whether it’s a rampaging baboon, a telepathic murder monkey, or a genetically modified killing machine, these films prove one thing: you should never trust a primate in a horror movie. And as we nervously peel a banana waiting for The Monkey to be unleashed on February 21, let’s take a moment to appreciate The Most Terrifying Monkeys, apes, baboons, and other family members that have already made us reconsider our zoo memberships. Because nothing says “fun night in” like watching a homicidal ape rip someone’s face off.
Monkey Shines (1988) – When Your Service Animal Wants You Dead
What happens when you inject human brain tissue into a helper monkey? Well, according to Monkey Shines, you get a homicidal primate with a serious attitude problem. This tiny terror is supposed to be assisting a paralyzed man, but instead, it taps into his suppressed rage and starts exacting vengeance on his enemies. It’s the kind of revenge fantasy you’d expect from someone who’s had one too many bad customer service experiences—except, in this case, the revenge is carried out by a knife-wielding monkey. Who needs a haunted house when your own emotional support animal is plotting your demise?
Congo (1995) – When Gorillas Go Corporate
Congo—a movie where humans venture into the jungle looking for diamonds and instead find themselves on the wrong end of a simian death squad. The film features a hidden city guarded by a pack of hyper-aggressive, supposedly extinct grey gorillas who have exactly zero tolerance for uninvited guests. These aren’t your typical zoo gorillas that just sit around peeling bananas—these guys are out here committing full-on, organized murder. It’s like The Godfather, but with more fur and sharper teeth. If you ever thought a diamond heist was a good idea, just remember: some treasures aren’t worth getting your face rearranged by an angry primate mob.

Primal Force (1999) – A Darwinian Nightmare
An island full of genetically engineered killer baboons? Sure, why not. Primal Force gives us a group of unfortunate souls who get stranded on an island where the baboons have evolved into hyper-intelligent, meat-craving murder machines. Because, of course, some lunatic had to play Dr. Frankenstein with the local monkey population. These creatures don’t just attack—they strategize. They hunt. They enjoy the kill. You know a movie has lost its grip on reality when the most believable part is the humans thinking they had a chance. Let’s face it: once you realize the jungle has a higher kill count than a slasher flick, it’s time to start writing your will.
Blood Monkey (2007) – Higher Education is Overrated Anyway
A professor takes a group of students into the jungle to study an undiscovered species, and—shockingly—things go terribly wrong. In Blood Monkey, the new species in question turns out to be less Curious George and more Bloodthirsty Jeffrey Dahmer in a Fur Suit. These monkeys are fast, vicious, and incredibly creative with their kills, making you wonder if they spent time studying human hunting tactics before deciding to start their own horror movie. What’s worse is that the professor in charge knew the risks and still went ahead with this field trip, which makes him either the worst scientist ever or an undiscovered serial killer. Either way, the lesson here is clear: if your college professor ever suggests a “research trip” to an uncharted jungle, drop the class immediately.
APE (1976) – A Middle Finger to Cinematic Standards
If King Kong had a cheap, rebellious younger cousin with a drinking problem, it would be APE. This low-budget disaster gives us a giant gorilla running amok in South Korea, complete with questionable special effects and the most iconic middle finger in film history—yes, the giant ape literally flips off its pursuers. It’s as if the filmmakers knew they were making a mess and just decided to lean into it. The gorilla itself is more terrifying for how bad it looks rather than its actual threat level, but hey, who needs realism when you’ve got a 36-foot-tall primate giving the world the bird?
Shakma (1990) – The Baboon That Woke Up and Chose Violence
A medical experiment goes south, and suddenly, we’ve got Shakma, a psychotic baboon turning a locked research lab into his personal hunting ground. Picture this: you’re trapped inside a building with an animal that looks like it just escaped from Satan’s petting zoo, and the only way out is past its slavering jaws. The baboon in Shakma isn’t just angry. It’s absolutely frothing at the mouth with primal rage, like it’s been cut off in traffic one too many times. And let’s be real: if a wild baboon ever locks eyes with you and starts sprinting in your direction, your best bet is to just make peace with whatever gods you believe in.
Planet of the Apes (2001) – When Monkeys Start Collecting Taxes
Tim Burton’s Planet of the Apes reboot doesn’t just feature scary apes—it gives us apes that run society. And let’s be honest, if primates ever take over the world, humanity is officially out of luck. The film presents a world where humans are the second-class citizens, and the apes have all the power. Ever wonder what it would feel like to be on the receiving end of a monkey’s bureaucratic nightmare? Well, this is it. The scariest part? Some of those apes seem more competent than actual world leaders.
King Kong (2005) – The OG of Giant Monkey Mayhem
Look, King Kong isn’t just scary because he’s enormous. It’s scary because he proves that no matter how big you are, love will still be your downfall. In Peter Jackson’s King Kong, our tragic ape hero is captured and shipped to New York. There, he proves why bringing a skyscraper-sized primate into a city is a disaster. Buildings crumble. People get stomped. By the end, Kong clings to the Empire State Building like a furry, doomed Romeo. If this film teaches us anything, it’s this—never let emotions cloud judgment. Especially when your love interest is 25 feet shorter and doesn’t speak gorilla.
Link (1986) – When Chimps Have Murderous Ambitions
A well-dressed, highly intelligent chimp who secretly dreams of killing humans? That’s Link. This movie gives us a seemingly well-trained chimpanzee who starts to act… let’s say problematic. One moment he’s doing circus tricks, and the next, he’s committing cold-blooded murder. The film is a slow-burn nightmare, where every polite little gesture from Link feels like it’s hiding a dark agenda. You can almost hear him thinking, You think I’m cute, huh? Just wait until you find out what I’ve done. If you ever needed a reason to avoid primates that can open doors, Link has got you covered.
If these films have taught us anything, it’s that monkeys in horror movies are never just innocent bystanders. They scheme. They kill and make you wonder if opposable thumbs were a mistake. So the next time you visit a zoo or consider getting a pet monkey, remember: today it’s throwing peanuts… tomorrow, it’s throwing you.
