Circus of Fear



""I mean, really, what kind of a demonically evil scheme involves rollercoasters and cotton candy anyway?""

- Murray the Demonic Skull, Escape from Monkey Island

Overnight, the circus came to town. But something's wrong -- very wrong. The circus music, which should be cheerful, seems menacing. The attractions (especially the freak display) seem off, the cotton candy is a sickly shade of green, the knife thrower doesn't miss, and the clowns...well, the less said about the clowns the better.

And people are disappearing, either consumed by or turned into the circus denizens.

This trope is the brother to The Little Shop That Wasn't There Yesterday, and often used in context with freaks, providing instances of either Red Right Hand or The Grotesque.

A common variation on the theme is a killer amusement park, with homicidal costumed mascots and a fun house that's anything but. If it's in a video game, expect a roller coaster that acts an awful lot like a mine cart.

Something Wicked This Way Comes, a novella written by Ray Bradbury and published in 1962 and turned into a movie in 1983, is a big inspiration for this trope, although the 1919 movie The Cabinet of Dr. Caligari is probably the Trope Maker.

Anime and Manga

 * The Dead Moon Circus of Sailor Moon.
 * Buggy the Clown's pirate crew from One Piece.
 * In episode 20 of Cowboy Bebop, Spike faces off against Mad Pierrot in a creepy circus inspired by the Batman animated series.
 * It's also called Space Land, and can be seen as a mockery of Bebop itself.
 * The titular Robot Carnival is one of these. It used to be a normal circus, but years of wear turned it into this and it turns the citizens into the towns it visits into its new performers. Or just makes them explode.
 * The season 1 finale of Team Galaxy features this, where the circus clowns kidnap humans for their performances.
 * There were hints of something called a "Nightmare Circus" sub-arc within the Mahorafest arc of Mahou Sensei Negima. Sadly, it was cancelled due to the main story taking up much more time than expected.
 * Black Butler has a whole arc in the manga where Ciel and Sebastian join Noah's Circus to investigate the whereabouts of children that have gone missing. Needless to say, what starts off as your average circus with jugglers, tightrope walkers, and acrobats turns much darker as we learn about the secrets behind it.
 * Near the end of the ultra- Squick horror manga Gyo, the protagonist visits a circus where all the acts are composed of or powered by victims of the "death stench" gas-producing virus that has ravaged Japan.
 * In Tite Kubo's short lived Zombie Powder, Balmunk has an entire Circus of Pain/Fear that just springs up from the ground.
 * The third opening of (Goku) Sayonara, Zetsubou-sensei.
 * Cat Soup has one, featuring a woman getting dismembered and a giant bird that's swallowed clouds (that ends up causing a flood).

Comic Books

 * The graphic novel "The Last Temptation" had one. Of course, it was written by Neil Gaiman and Alice Cooper.
 * In the Marvel Universe, the Circus of Crime was a front for criminal activity. It consisted of guys like Bruto the Strongman, Princess Python, the Human Cannonball, the Great Gambonnos, the Clown, Live Wire, and the variously threatening-and-not so much Ringmaster, whose hypnotic hat was often the key to his schemes. Generally less overtly creepy and homicidal than other examples of this trope, the Circus of Crime is mostly in it for the money.
 * Marvel villain Arcade's deadly amusement park, Murderworld, also has elements of the Circus of Fear, and so far hasn't fallen to Villain Decay. Probably because he has so many Murderworlds.
 * Also in the Marvel Universe, in a New Mutants flashback, they find a circus, it's run by Skrulls who are kidnapping humans and shrinking them. As expected, the New Mutants trash the place, including various structures that didn't need it.
 * Slapstick, another Marvel hero resurrected in the aftermath of the Civil War, got his start trying to save his classmates from Evil Clowns From Dimension X who were using a circus to kidnap people and turn them mediocre. No, really. Everything got righteously smashed up.
 * The Joker likes doing variations of this in the various Batman incarnations. Most famously, he buys an Amusement Park of Doom in The Killing Joke and crews it with circus freaks, using it to  And there was a song.
 * Also from Batman, in Grant Morrison's Batman and Robin, the first arc features an evil circus troupe lead by the Nightmare Fuel inducing Professor Pyg. In the second issue, the new Robin visits the actual circus and more Nightmare Fuel starts when he is attacked by Professor Pyg's masked henchmen.
 * Pyg's major underlings all resemble sideshow freaks, as well, including a grossly overweight bearded lady in a tutu and a human flame act who can burn others but not himself.
 * In Spider-Man Noir, Norman "The Goblin" Osborn recruited his inner circle from the circus freak show. The Vulture was a geek who had become more animal than man, Kraven was an animal tamer, the Chameleon had the uncanny ability to alter his facial features, Ox was a strongman, Montana did rope tricks, and Fancy Dan was probably a promoter or something. As it turns out,
 * The Real Ghostbusters fought a ghost-circus in their comic-book incarnation. The zombie elephants were somewhat creepy.
 * The second arc in the first volume of I Hunt Monsters has the heroes dealing with a circus run by werewolves.
 * An early arc of James Robinson's Starman features this type of circus. The "freaks" themselves are mostly nice people, but they are controlled by the ringmaster and his evil lieutenant. Because this is Starman, the lieutenant comes back during the invasion of Opal City.

Film - Animated

 * The Big Bad for the movie We're Back! A Dinosaur's Story runs a 'literal' Circus of Fear. Everything in it is geared towards horror. Except for the clown, ironically enough.
 * The obscure film known as Felix the Cat: The Movie takes place in one of these for most of the film, since the Big Bad sends the Damsel in Distress there to perform for his amusement.
 * Invoked in Disney's Pinocchio where some of the crates the Coachman locked about half the Donkey Boys in appear to be heading for a circus (the other crates were heading for the salt mines).

Film - Live Action

 * The film Batman Returns had the Penguin secretly running one such circus that abducted children.
 * Two-Face's goons dressed up as two-sided clowns when they attacked the circus in Batman Forever.
 * Briefly but memorably used in Darkman. The barker's shouts of "Freak!" coincide perfectly with Liam Neeson losing his temper.
 * The movie Freaks both used and defied this trope. The freaks are all loving and caring people, the clowns are good-natured and charming (although one of them has a hilarious speech-impediment), and the animal trainer is frigging gorgeous. There's a bit of black comedy involving a pair of conjoined twins, one of who is getting married, and the soundtrack is slightly creepy, but that's about it. Unless you get them angry, as the evil female trapeze artist and misogynistic strong man do. Do NOT get the freaks angry.
 * The movie version of The Elephant Man involves the title character's escape from one of these. The movie was directed by David Lynch, who must have jumped at the chance to try his hand at this trope.
 * No prizes for guessing what the Hammer horror film Vampire Circus is about.
 * Before he gets to the famous Hall of Mirrors Michael O'Hara from The Lady From Shanghai, is dumped in one of these.
 * Killer Klowns From Outer Space!
 * As noted above, The Cabinet of Dr. Caligari is probably the Trope Maker.
 * The movie Waxwork is about a group of teenagers coming across an evil waxwork museum.
 * Christopher Lee starred in a 1966 fim actually titled Circus of Fear.
 * A mild subversion; in the James Bond film Octopussy, the titular female lead uses a circus as a cover for her criminal activities as well as using circus acrobats and aerialists to commit crimes for her, while a renegade Soviet general plants a nuke in her circus. Not necessarily evil, but initially misguided.
 * A.I.: Artificial Intelligence and its "Flesh Fair".
 * Texas Battle Land from The Texas Chainsaw Massacre 2.
 * The Incredibly Strange Creatures, one of the worst movies of all times, is set in a carnival where patrons are transformed into zombies. The film actually features surprisingly few zombies and much, much, MUCH more bad singing than would be expected.
 * The Devils Carnival is about a carnival run by...guess.

Literature

 * The Carnivorous Carnival
 * Angela Carter's Nights at the Circus doesn't feature an evil circus per se, but some scary and strange crap definitely goes down.
 * One of TSR's Endless Quest books was actually called Circus of Fear, involving
 * In several Incarnations of Immortality books, ghosts run an ethereal amusement park, where the ghosts try, and often succeed, in scaring the visitors. Amusingly, people kissing seems to scare the ghosts, in return. However, the rest of the amusement park is typical, if ghostly, fare such as a smoke ring toss.
 * Give Yourself Goosebumps #1 is called "Escape from the Carnival of Horrors". And then much later there came "Return to the Carnival of Horrors", because apparently you just can't stay the hell away. (To be fair you're bullied into it by the book itself in the first entry (after all what the point of reading it). In the second entry you brave it once again to get your oblivious cousin out.)
 * Played straight with a later Choose Your Own Adventure book called Trapped in the Circus of Fear.
 * Subverted in The Saga of Darren Shan, where the "Cirque Du Freak", though intended to be nightmarish and slightly horrifying (not to mention potentially dangerous), actually provides a warning beforehand of what it will be like, and gives patrons an opportunity to leave. If any are injured, the show is halted until they are fixed up. Also, the "freaks" are rather friendly and personable people, and the Circusmaster, Mr. Tall, actually runs the cirque as a means of providing people with strange abilities with shelter, family, the opportunity to travel, and a circumstance where their unique abilities can inspire wonder rather than fear.
 * Something Wicked This Way Comes, of course. Its carnival is strongly implied to literally thrive on fear and unhappiness.
 * The Pilo Family Circus. An extradimensional travelling circus of madmen, magicians, and monsters, where the employees are paid in bags of management-controlled wishing powder made from the crystalised remains of human souls- extracted from the audience, of course. Oh, and the managers have a nasty habit of causing global chaos on Earth via the Fortune Teller and the Clown division, on behalf of a race of reptilian demigods imprisoned beneath the showgrounds.
 * Redwall's Slagar the Cruel runs a traveling show which seems perfectly benign (except that all the performers are weasels and stoats). The show is used to distract the good guys while a performer drugs their drinks and Slagar himself hypnotises them, and when they wake up the "show" has vanished, taking their children with it.
 * Count Otto Black, a Running Gag recurring villain in Robert Rankin's insane versions of novels, is often seen running a circus.
 * Jean-Claude, from the Anita Blake series, owns and runs a fully functioning vampire circus, clowns with fangs and all.
 * The Theater des Vampires in The Vampire Chronicles, who are of course vampires hiding in plain sight. They manage to be both scary and complete jackasses at the same time. They act out vampires killing humans on stage while the human audience watches in oblivious entertainment, and sometimes even satirically offer themselves in place of the victim they don't believe is a victim.
 * Not a circus, but an amusement park - Full Tilt by Neil Shusterman. Good god, Full Tilt.
 * The Buffy the Vampire Slayer novel, 'Circus Of Souls'. She figures it out soon enough, but is then zapped by the brain-altering magics of the circus.
 * The Manual of Detection has Caligari's Travels-No-More Carnival, which is this trope in spades.
 * Nick Harkaway's The Gone-Away World subverts this by having a circus help and support the good guys.
 * The Circus of Doctor Lao, the one novel by Charles G. Finney. One amazing novel.
 * The setting for the Ravenloft novel Carnival of Fear.
 * According to the short story "A Boy and His Monster" in Star Wars: Tales From Jabbas Palace, Malakili the Rancor Keeper was previously employed by the Circus Horrificus, where Hutts paid to see weird creatures get tortured to death.

Live Action TV

 * Doctor Who, during the 7th Doctor's tenure, had the Psychic Circus in The Greatest Show in the Galaxy.
 * There was also an untelevised script for a Sixth Doctor story called The Nightmare Fair, later released as a novel, then an audio play (unofficial) and then an audio drama (official). The circus in question belongs to an enemy called the Celestial Toymaker.
 * Torchwood series 2 had the Night Travellers in the episode "From Out of the Rain".
 * The Sarah Jane Adventures series 2 had Spellman's Magical Museum of the Circus in the story The Day of the Clown.
 * Mighty Morphin Power Rangers, first-season episode.
 * Ace Lightning's appropriately named Carnival of Dum Doom.
 * One episode of So Weird.
 * One episode of Star Trek: Voyager had a circus that was literally run by an anthropomorphic manifestation of fear (depicted as a Monster Clown, naturally).
 * Papa Lazarou's circus in The League of Gentlemen might qualify as a subversion. While Papa Lazarou's appearance is pure Nightmare Fuel and he spends all his spare time kidnapping women ("You're my wife now!") Royston Vasey is already so full of freaks that the circus soon flees in terror, as the town is too weird even for them.
 * Carnivale embodies this.
 * Heroes Was headed in this direction. The final season opened with the role of primary antagonists falling on a group of carnies, led by a man named Samuel who In the end it turns out this is a slightly subverted troupe as the circus was a protected home for people with powers where they could openly be themselves.
 * Well, most of the carnies aren't really evil, just misguided.
 * An episode of Mutant X dealt with a travelling circus led by a man whose power was to trap people inside funhouse mirrors.
 * The short lived series She Wolf of London (aka Love & Curses) featured an episode during it's first season, Big Top She-Wolf, that dealt with a demonic circus.

Music
"Come inside, for the ride, Your deepest, darkest fear! The best night, of your life, You're never leaving here! The unknown, the unseen, Is what you'r gonna find! Witness this, witness that, Untill you lose your mind!"
 * A lot of Tom Waits' stuff, especially the albums "Swordfishtrombones", "Frank's Wild Years", "Rain Dogs", "Alice" (which includes a song about Johnny Eck), "The Black Rider", and "Blood Money".
 * "Circus of Death," from the Human League's first album Reproductions, tells the story of a singularly destructive circus. The song is also, oddly enough, a Hawaii Five-O Fanfic of sorts.
 * Insane Clown Posse's appearance and Dark Carnival mythos is based on this trope. Many of their songs, including "Murder Go Round", "House of Mirrors", "Halls of Illusion" and "Tilt-a-Whirl" relate to Circus, or rather, Carnival of Fear-based themes.
 * The cover art, title track and its music video, and associated merchandise (comic books, action figures and a CD-ROM game) of the 1998 Kiss album Psycho Circus make use of this concept.
 * This is kind of the whole schtick of Seattle-based group Circus Contraption, especially during their "Grand American Traveling Dime Museum" show.
 * Creature Feature's "The Greatest Show Unearthed". is all about this:

"Come down and join the circus It's the end of your world Come down and join the circus All you dead boys and girls If you still have a pulse We can remedy that You can check your life While you check your hat"
 * Nox Arcana's CD Carnival of Lost Souls is based on Something Wicked This Way Comes, so of course features one of these.
 * Emerson Lake and Palmer and their "Karn Evil 9". Welcome back my friends to the show that never ends...
 * Bob Dylan's "Ballad of a Thin Man," if the lyrics are taken literally, takes place at least partially in a Circus of Fear.
 * The video for "I Stay Away" by Alice in Chains, made even creepier by the use of somewhat grotesque puppets. The song doesn't really have much to do with it.
 * Circus of Sour by Donovan doesn't sound like it's about a particularly nice circus.
 * A lot of Hannah Fury's music evokes feelings of this, but "Carnival Justice (The Gloves Come Off)" especially makes use of some creepy carnival imagery.
 * The artwork for Mr. Bungle's self-titled first album centers around this trope, as does the song Carousel (off the same album).
 * "Dark Woods Circus" of the Vocaloids. Perfect example.
 * Circus Apocalypse by the dark caberet act, Vermillion Lies.


 * The dark cabaret act Circus Contraption is MADE of this trope.
 * Pink's Funhouse Tour featured quite a few freakish clowns. The name comes from one of her songs: "This used to be a fun house/But now it's full of evil clowns".
 * The song Greasepaint and Monkeybrains by White Zombie. It even starts with a circus calliope breaking down mid-song.
 * Poets of the Fall has the awesome song/music video"Carnival of Rust". It is run down. It is creepy. It has a girl in a gas mask. It. Is. Awesome.
 * The Concept Album The New World's Fair by Michael Moorcock and his band Deep Fix (yes, Michael Moorcock sang and wrote songs!) involves the denizens of a carnival in a post-apocalyptic world.
 * 'Circus metal' is slowly becoming its own sub-genre for a combination of circus music (or more generally dark cabaret) and metal. Good examples of this are Stolen Babies and Unexpect.
 * The circus folk in Panic At The Disco's "I Write Sins Not Tragedies" are a subversion since, while definitely creepy, they're actually the good guys.
 * The aptly named Dark Cabaret group The Carnival are centered around this.
 * Nightwish's song Scaretale has a part like this.
 * As does the music video for Storytime.

Tabletop Games

 * The Swords & Sorcery "Scarred Lands" setting has an entire Circus of Fear nation. The Carnival of Tears in Blood Bayou.
 * Appearing in the Warhammer Fantasy Battle spinoff game Mordheim, and referenced in Warhammer too, is the Carnival of Chaos, a circus staffed by Chaos worshippers and daemons of Nurgle (who, despite being the Chaos God of despair, is a rather jovial fellow). The show itself probably isn't that bad, but it spreads deadly diseases wherever it performs.
 * The Warhammer 40000 roleplaying game Dark Heresy introduces The Menagerie, which uses carnivals, revels and fetes as a cover to expose innocent people to sanity-blasting, flesh-warping horrors. Come and see! You must come and see!
 * Dungeons and Dragons
 * The titular organisation from Ravenloft's Carnival box set seems like this at first, with the workers divided roughly between mutated freaks and spooky, utterly silent folks in bizarre face paint, many of which work as rather disturbing clowns, but it actually subverts the trope. The Carnival is one of the most accepting and hospitable places in the Demiplane of Dread, and most of the workers are good people. Most of them... there are some members who are actually evil, though they've managed to hide this from their fellows. One of the options for the true nature of Isolde, their leader, (and which has more or less been adopted as the truth), is that . The original workers for Isolade's Carnival, however, are escapees from a now-dead Darklord called "The Puppetmaster", who ruled a domain (the Carnival l'Morai) that played this trope straight (Carnival of Fear, mentioned in Literature above, deals with the original domain, not the current Carnival).
 * Despite all this, as is only appropriate in Ravenloft, the Carnival's still very creepy. The Skurra are attendant Vistani who wear strange black and white facepaint (the Skurra-verra) that protects them from the Twisting at the cost of making them mute. The Twisting causes people who stay overlong in the Carnival to mutate, their form changing to reflect their hearts and souls- for example, the bitter and malevolent Professor Pacali's repressed plots take life as deformed midget "things" that grow from his flesh. This is the source of his "Pickled Punks". One of the "attractions" are the horrifically warped Chaos Spawn-like remnants of people who attacked the Carnival, entities referred to simply as The Abominations. And some of the populace were strange and unnatural before they entered the Carnival, like a bloodthirsty leopard with the ability to assume a humanoid form, a Seawolf (an amphibious werewolf), the Fetch of an evil wizard and a Wax Golem.
 * 1st edition supplement Adventure Pack I, adventure "The Circus of Gandolfo". The title circus is just a cover for a Doctor Frankenstein-like Mad Scientist who likes to kidnap people and perform bizarre experiments on them.
 * An Old World of Darkness supplement titled Midnight Circus detailed something very much like this, containing all manner of supernatural creatures enslaved to a mystic travelling circus dating back to the Roman era. It was disturbing even by World of Darkness standards.
 * In the New World of Darkness, Vampire: The Requiem gives us the vampiric bloodline called the Carnival. Every last vampire of the bloodline bears a circus-freak deformity (their founder suffered from sirenalia, and was billed as "the Andalusian Mermaid"), and they often act as traveling or static carnivals, the better to hide in plain sight.
 * The Pathfinder module Carnival of Tears showcases a carnival where icy fey have taken over, and are slaughtering the attending townsfolk in gruesomely creative ways. No one notices, due to powerful illusion magic that replaces every event of horror with a completely normal, even enjoyable, carnival scene.
 * Magic the Gathering has the sado-masochistic hedonist Cult of Rakdos with its [[media:Rakdos Carnarium Cropped 851.jpg|circuses]] of DOOM.
 * One of the playable "families" in the card game Gloom is Darius Dark's Den of Deformity. One of the characters is a scary clown with a skull-like face. The description for Darius Dark himself is: "The circus is in Darius' blood. And there is an awful lot of blood in Darius' circus."
 * The Circus Maximus for GURPS.
 * Also for GURPS, Poponax the Evil Clown's carnival from the Magic Items 2 sourcebook. The carnival itself is relatively harmless, but all the prizes and souvenirs the visitors receive are cursed.

Video Game
"Raz: My memories were bad enough. This is just gross."
 * The higher levels of play in the MMORPG City of Heroes include a "Circus of Fear"-style villain group called the Carnival of Shadows.
 * The members of the Carnival feed on their patrons' souls.
 * This is the theme of two levels in Donkey Kong Country 2. Interestingly, these circus levels have nice music, and a fun Mine Cart Madness design. However, it's a tad odd that levels in the same section of the game, including the boss fight, take place inside a giant beehive.
 * Possibly Krazy Kremland was intentionally built in a pantanous, bee-infested area to try and keep any apes away. Or, given how run-down it is (there's a bramble level inside the park area) it was a normal amusement park before, but it became abandoned in such a way the Zingers made their hives there.
 * At the end of the game Psychonauts, Raz (the protagonist) accidentally merges his mindscape with the villain's. Since Raz grew up in the circus, his mind is molded to resemble a giant circus tent. However,  So, what do you get when the two minds collide? A horrible, twisted circus where nearly everything is made of meat.

""You ever been to a carnival? You know that game they have with the water guns and they're shooting water into these clowns' mouths and there's a water balloon that inflates and inflates, eventually it explodes, everybody's happy, whoever won the race gets a prize from, you know, the carny who's got, like, three thumbs on both hands, you know what I'm talking about? Well, that's basically this level. Except for the part where everybody's happy. This level's hard.""
 * Raz' remark above implies that his own (real, not that dream he had because Sasha had to go and buy the cheap Brain Tumbler) mindscape wouldn't be so much fun to begin with. He gains new perspective on his old memories at the end of the game, though, which leads me to wonder what it might look like now.
 * And the heartstring tugging
 * Furthermore, the music fits the bill completely. Just listen to it.
 * The first Shining Force game for the Genesis had a circus-based level, with a powerful marionette heading up the attacking forces (clowns included).
 * Okay, so it's a carnival, but Tokkentakker's little three-ring terror ride that is the basis of the arcade game Carn Evil certainly fits the bill, complete with demonic floating clown head.
 * The theme park from Silent Hill 3 is the Dark Silent Hill version of a theme park. Come for the faceless fairytale characters, stay for the hooded, twitching carousel flesh-horses and dark echoes of previous lives!
 * Lakeside Amusement Park is actually first visited near the end of Silent Hill 1, and also features a bloody battle on the carousel, this time with.
 * The first mission of Circus Park in Billy Hatcher and the Giant Egg certainly fits the bill.
 * And the second stage too. Sure, it may not be dark anymore, but that's a pretty messed up funhouse you have to go through.
 * The Nation of Fools from Castlevania: Portrait of Ruin. Enemy types include demonic clowns and evil acrobats. The circus appears to be in some post apocalyptic world surrounding a black hole.
 * Don't forget the creepy mock-circus music just to drive the point home.
 * There was also another Circus Level at the Hub Level within the Hub Level
 * LeChuck converts a part of Monkey Island into an amusement park of doom (the "Carnival of the Damned") in The Curse of Monkey Island as part of his master scheme: Reasoning that the first thing a sailor wants when he arrives to port is a family-oriented fun-park, he builds the Carnival of the Damned, and its centerpiece ride, the Rollercoaster of Death, leads straight into Big Whoop and converts everyone who boards the ride into a ghost pirate minion.
 * House of the Dead: Overkill has one with Mutant Clowns and a freakshow complete with a freak as a boss. A freakier freak than a normal mutant.
 * Earthbound has this in the city of Threed. It already starts off with a scary circus and a town overrun with undead/spectral monsters. The trope is inverted at first, as the big top is the sanctuary for townspeople. When another circus tent mysteriously shows up, the trope is played with a Nightmare Fuel-inducing variation, as
 * The aptly named Wonky Circus in Wario World. There's also the circus setting for the third boss (Chortlebot) in Wario Land: The Shake Dimension, although it's only ever used as a battle arena against said Monster Clown.
 * Take your average Circus of Fear, add in untold volumes of molten rock for all the geothermal power you'll ever need, have the whole thing built in a week due to harnessing the powers of a Cosmic Horror, and staff it with robots out the ass. Welcome to Eggmanland. Enjoy your stay.
 * Also, Sonic The Hedgehog 3 had Carnival Night Zone. The music could be described as an Ear Worm, and we'll never forget that damn barrel...
 * Also Shadow the Hedgehog has Circus Park, which is also an Amusement Park of Doom.
 * Earthworm Jim 2 provides an example with Circus Of The Scars, also known as Inflated Head, best summed up by Something Awful forumite Phiggle in his Let's Play of the game as such:
 * Earthworm Jim 2 provides an example with Circus Of The Scars, also known as Inflated Head, best summed up by Something Awful forumite Phiggle in his Let's Play of the game as such:


 * Donbalon's stage from Ni GHTS: Journey of Dreams probably qualifies for this.
 * Neopets has the flash game aptly named Carnival of Terror and has a world called The Deserted Fairground. Both are located in the Haunted Woods.
 * Kiss Psycho Circus is Exactly What It Says on the Tin
 * One of the levels in Painkiller: Overdose features a spooky circus Of Doom.
 * The Legend of Zelda Majoras Mask has a giant music box that plays what can only described as scary circus music. It doesn't even help much that it also scares the mummies away.
 * It actually makes it worse: music that is so bad that even the undead can't stand to hear it.
 * Ape Escape takes this trope and packs pretty much every element into the first half of the first game's monstrously huge Very Definitely Final Dungeon. The main area is an amusement park taken over by the Big Bad, with lots of separate areas branching off, including a crazy mine cart style roller coaster, and a more literal circus flavored area, where you must defeat an evil clown. The other sections are mostly other common video game settings, including Wild Wild West and a Big Boo's Haunt. Note that this is only the first half of the level. The other, even longer, half is the Big Bad's flying castle, which includes elements of Tomorrowland. Yeah, this series really likes its location tropes.
 * Fall From Heaven 2 has a whole nation, the Balseraphs, based on this trope and Crazy Awesome, ruled by a Monster Clown and his Creepy Child daughter.
 * Blood's "Dark Carnival" in the first episode is supremely twisted. Aside from a lantern-carrying statue of Death siccing zombies on you when you ignore his request for a ticket, the optional game where you kick a severed head through a slowly opening and closing mouth to win a prize, or the secret funhouse level that shoves rotting skeletons at you while maniacal laughter plays, there's also the fact that the whole place is basically built next to an evil temple filled with cultists who want you dead. Well, deader.
 * The second Soviet mission of Red Alert 3 which takes place in a vagrant carnival built on an abandoned rocket test site. It seems sparsely populated until the Soviets activate the abandoned launch facility upon which Japanese troops (including a Psychic Commando) burst out of the tents and surround the Soviets. The actual mission itself is called something along the lines of "Carnival of Hatred".
 * The Residents' Bad Day On The Midway PC game was one of these.
 * The first level of Dark Cloud 2 had one of these coming to Max's town, which culminated in a boss fight against the deranged clown Ringmaster and his pet elephant, Linda. And then he chases you onto a train and throws bombs at you until the whole train derails.
 * Marvel Ultimate Alliance has a level in Murderworld, mentioned in the Comics section. Complete with kamikaze bots, android copies of party members, and clowns with radioactive flower-squirts.
 * Gaunlet: Dark Legacy had one of these as a final level.
 * Time Splitters2, with info about it on this wiki featuring all kinds of Nightmare Fuel characters in the Circus of Fear theme, like murderous clowns.
 * In World of Warcraft, the Darkmoon Faire is a recurring event, and definitely qualifies for this trope. It is most assuredly not a wholesome thing; much of the staff is undead, the colours are flatly ugly, the designs on the tents are disturbing, and then there are the quests.
 * With patch 4.3, it get's even creepier, as you now go to Darkmoon Island. When you enter the portal, you end up in a very ominous forest with gnarled, apparently dead trees. The signs that point you to the fair mention "ignoring the eyes" in the forest. There was some mention of never wandering too far into the woods... And if you decide to look around you might find some cages filled with humanoid skeletons, and a forsaken woman selling some rather questionable meat products.
 * Then there's that all-seeing eye at the entry gate that looks a lot like it belongs to one of the raid bosses... and the NPC who stumbles over his words as he almost says that the Master would be interested in certain items. It is very heavily implied that the Faire is related to the Big Bad of that expansion.
 * Painkiller:Battle out of Hell has a circus/ fun fair called Loony Park with killer clowns and monsters made out of snack food.
 * Ryan Amusements in Bioshock's Rapture is designed mostly as a propaganda device to scare children into never going to the surface.
 * One level in ASC's Sanitarium has this. Of course, it's a delusion...
 * Sweet Tooth's circus in Twisted Metal 4 features such attractions as the "roller toaster", aside from being a battleground where the demented clown and a number of assorted psychos try to kill each other.
 * The reboot gives us Sweet Tooth's Carnival of Carnage, built by his worshipers . Not only is it a mobile carnival, its a Circus of Fear Humongous Mecha Base on Wheels Military Mashup Machine flanked by many psychotic clowns carrying chainsaws, suicide bombs and/or piloting transforming ice cream trucks. And the entire thing is the Final Boss. Just friggin' look at it
 * The downloadable Loon track in POD featured deformed fairytale castles, giant roulette wheels, an enormous wizard hat and rusted metal plates, located on a planet infested by an alien virus. Or is it? When you look over the guardrails, there is only a black void there...
 * Stage 6 in Silent Assault.

Web Comic

 * Mort from Gunnerkrigg Court creates one of these at Antimony's suggestion to scare her classmate Paz.
 * Gamzee from Homestuck more or less has this as his overall intention now that he's "sane", a turn of events which could arguably be the most utterly terrifying moment in the comic to date. Just listen to "Midnight Calliope" or "The Carnival". It's recommended you have a spare pair of pants on hand.

Web Original

 * It has been announced that once Grave Academy starts, a part of the academy or a separate location will be this.
 * An episode of the Flash series Xombie had Dirge and Zoe fighting a horde of zombie clowns in an abandoned amusement park, while Dirge's undead dog Cerebus Cerberus faced off against a zombie tiger.

Western Animation

 * Mighty Orbots had to deal with "The Cosmic Circus", a fake circus designed to duplicate key members in the Galactic Patrol. Was actually kinda creepy.
 * Episode 9 of Ben 10, "Last Laugh", feature a circus led by Energy Vampire Monster Clown named Zombozo, whose members included : Acid Breath, a zombie-looking man breathing acid; Thumbskull, a Dumb Muscle strong man with a broken horn on his head; and Frightwig, a Dark Action Girl with Combat Tentacle as hair.
 * One episode of The 13 Ghosts of Scooby Doo.
 * Scooby Doo uses this trope a lot. Circuses, carnivals, amusement parks, or anything similar.
 * A possible varriation: an episode of My Little Pony involved the witch Somnambula inviting the ponies into her illusionary carnival, where she steals their youth.
 * Taken from Something Wicked, at least the movie; in the book, the reverse happens to
 * Circus Gothica in Danny Phantom.
 * Rayman: The Animated Series has one of these as the whole plot setting. Did I mention half the cast are kids?
 * An episode of Loonatics Unleashed had one where Biological Mashups are made and used to perform.
 * A Captain Caveman episode on The Flintstone Comedy Show, "Clownfoot," featured the episode's villainous clown, Clownfoot, using a circus as his hideout. At said circus, Clownfoot also rigs a tandem bicycle Wilma and Betty are riding on a high-wire to fall apart, over a cage full of hungry saber-tooth tigers.
 * Tiny Toons had a Whole Episode plot where Dodo got caught trying to rescue some Wackyland residents from a very-Satanic-looking Ring Master, then Bugs, Buster, and Plucky had to rescue him when he gets caught. They never really show the rest of the circus, but the Ring Master's treatment of the Wackylanders is pretty nightmare-inducing.
 * Episode 12 of Super Robot Monkey Team Hyperforce Go!, "Circus of Ooze".
 * Mighty Max has an episode where an Evil clown named Freeko kidnaps children, and morphs them into creatures for his freakshow. This episode, as one would expect, is brimming with horror
 * The Funhouse in Re Boot. One of the rarest games on the Net (because only User children play it) and is nearly impossible for sprites to beat. Bob and Dot are the only confirmed sprites to escape it alive.
 * "Wild" Bill Krebb's sideshow in Adventures of the Galaxy Rangers episode "Showtime." the performers are slaves, the acts have zero safety net, he gladly exploits the fact that Andorians go feral in captivity. And this was a lighthearted episode...

Other

 * Black Phoenix Alchemy Lab made a series of perfumes with collectible cards designed around the "Carnaval Diabolique".

Real Life

 * Carnival Diablo: The Ultimate Sideshow plays on this trope. The Carnival is run by the Devil, and the performers are presented as other-worldly beings with bizarre abilities. Many acts seem to put performers, and sometimes audience members, in danger.
 * The Circus of Horrors is a real circus show that plays on the trope.
 * The mad clowns, Heckles and Twitch.
 * Hell, we can go all the way back to the beginning with the original Roman-style circus (gladiator fights to the death and Christians being fed to wild animals), making this trope Older Than Feudalism. However, the "attractions" were only scary to the people in the pit as most Romans enjoyed these public displays of violence.
 * Circus Circus in Las Vegas has a 3D motion ride with this trope as its theme.
