'''[[BrainBleach BRAIN BLEACH]] WARNING''': Just ''reading'' about '''''The Human Centipede''''' could make you wish you hadn't.

Still with us? Well, don't say we didn't warn you.

In 2010's ''The Human Centipede: First Sequence'' (directed by Tom Six), two young American tourists, Lindsay and Jenny, find themselves traveling through Germany when they [[MyCarHatesMe get a flat tire]]. They stop for help at the house of [[DoesThisRemindYouOfAnything Dr. Josef]] [[HerrDoctor Heiter]] ([[AwesomeMcCoolName Dieter Laser]]), a surgeon who specializes in separating conjoined twins -- and a man [[MadDoctor with a vision]]. We'll let you get a cold drink and a comfy seat before we share [[BodyHorror his vision]] with you. If you like to drink alcohol, make your drink a [[INeedAFreakingDrink stiff one]].

Ready? Okay, here we go.

Heiter seems to have read ''FrankenFran'' a lot -- especially the second chapter. He dreams of taking separate individuals and stitching them together to [[BodyHorror create]] a "human centipede" that shares a single digestive tract. (Take a minute to let that sink in if you need to.) For the sanity of our readers, we will not describe how he plans to accomplish his goal here, but to bottom line it: Lindsay, Jenny, and a JapaneseTourist named Katsuro have just become his first test subjects.

Billed as "100% medically accurate," ''The Human Centipede'' gained plenty of early attention from horror fans and sites due to its [[AudienceAlienatingPremise depraved premise]]. (Riding on a wave of graphic European horror films helped the film, too.) The film often receives a mixed reaction from horror fans who can stomach watching it: some believe it went to amazing lengths with its premise, while others feel it relied too heavily on BodyHorror at the expense of scaring viewers.

The film found enough success at festivals around the world to warrant a {{sequel}}. 2011's ''The Human Centipede II (Full Sequence)'', filmed and set in England -- where the ratings board {{banned|InChina}} the uncut version until the filmmakers cut almost three minutes of footage -- centers around a PsychopathicManchild named Martin who becomes obsessed enough with the [[ShowWithinAShow first film]] to try imitating it; however, this time the centipede is longer than three people. Tom Six says the sequel makes the original film look like ''Franchise/MyLittlePony''; judging by people's reactions to the finished product, the sentiment comes off as legit. While the filmmakers billed the first film as "[[DanBrowned 100% medically accurate]]", Six described the sequel as "100% [[YouFailBiologyForever medically]] [[TakeThatUs in]][[LampshadeHanging accurate]]".

Six has completed principal photography on a third movie, and despite reports of [[http://www.joblo.com/horror-movies/news/the-human-centipede-is-falling-apart-tom-six-suing-actor-dieter-laser a falling out]] between Six and actor Dieter Laser, both Laser and Harvey will return, but as different characters. It will be set in a prison and Eric Roberts, of all people, is to play the prison governor. The film is currently in post-production in Amsterdam and is due for release in 2014.

The films somehow spawned a [[LighterAndSofter light-hearted]] porn parody, ''[[ParallelPornTitle The Human Sexipede]]'', and inspired the Season 15 premiere of ''WesternAnimation/SouthPark'' ("[=HUMANCENTiPAD=]"). Someone also got the bright idea to make a ScreenToStageAdaptation in ''WebVideo/HumanCentipedeTheMusical''.

----
!!Provides Examples Of:

* AllAnimalsAreDogs: Heiter attempts to invoke this with the centipede by trying to get it to fetch the newspaper.
* AllJustADream: [[spoiler:The ending of the sequel seems to imply that Martin simply daydreamed it all.]]
* AndIMustScream: Well, you ''can'' scream... it's just that you can only scream up someone's ass. [[spoiler:This is also Lindsay's ultimate fate, with Heiter and the other two members of the "centipede" dead, [[FateWorseThanDeath leaving her stuck between two dead bodies]] with nobody to help her]].
** In the sequel, the same applies, with Miss Yennie being the only one in the centipede to scream clearly. Martin finds this annoying, so he resorts to pulling out her tongue with pliers.
* [[AsHimself As Herself]]: Ashlynn Yennie appears as "Miss Yennie" in the sequel.
* AssShove: [[spoiler:Martin ends up on the receiving end of this when Yennie finally snaps.]]
* AssholeVictim: [[spoiler:A good portion of Martin's victims in the sequel are people who have wronged him somehow: his mother, his psychiatrist, the rude couple at the beginning, the skinhead upstairs neighbor, etc.]]
** [[spoiler:Katsuro, right before he kills himself,]] accuses himself of being this
* AwesomeMcCoolName: The actor playing Dr. Heiter is called ''Dieter Laser''.
** The actor playing Detective Voller is named Peter ''Blankenstein''.
* BeautyIsNeverTarnished: Subverted.
* BilingualBonus: "Heiter" is German for ''cheerful''.
** An awful lot of the first film is in German and Japanese. Unless you have the DVD subtitles on or know those languages, you're kind of screwed.
* BodyHorror: Good ''lord''. They even go into ''graphic detail'' on what the procedure involves. [[spoiler: The cheeks (of the mouth) [[GlasgowGrin are cut]] and grafted onto the cheeks (the other kind) of the person in front of them in such a way that the mouth is enclosed around it and that the person can't even breathe through it, and can't move their jaw without ripping the flesh. Some teeth are also removed]]. Probably the only horror film where ''you don't even need to '''see it''' to be horrified''.
* BreakTheCutie: Lindsay and Jenny.
* BrokeTheRatingScale: Creator/RogerEbert ''[[http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20100505/REVIEWS/100509982 refused]]'' to give the first film a rating. To be fair, he has done so in the past, for films such as this and ''Film/PinkFlamingos'', where rating a movie would be pointless, as a director or prospective viewers couldn't possibly care about it.
** On the other hand, he gave the sequel zero stars, because it was "reprehensible, dismaying, ugly, artless and an affront to any notion, however remote, of human decency."
* CrackFic: ''FanFic/TheHuemnCeniped2TheHumenMilipede''. Perhaps the author went insane after watching the film.
* CreepyCentipedes: Not the literal one but close enough....
** Played straight with Martin's pet centipede in the sequel.
* DangerousKeyFumble: Lindsay ''deliberately'' drops the keys (for some reason) after locking herself in the [[MorallyAmbiguousDoctorate doctor's]] bedroom. She then realizes what a dumb idea this was, when the doctor then appears at the window with a tranquilizer rifle.
* DaylightHorror: Once the operation is complete, the film gets very bright and sunny visually.
* DeliberatelyMonochrome: The second film, because the director felt it was scarier in monochrome.
** Plus, if it was in color, it most likely would have been edited down ''more'' than it already was in monochrome.
* DevelopingDoomedCharacters: The {{decoy protagonist}}s that the film opens with are not only horribly written characters, but also horribly acted. Not that you wish the horrors they later endure on them, but they're ''very'' annoying and unsympathetic.
* DoesThisRemindYouOfAnything: An insane German scientist wishes to try a potentially-deadly and BodyHorror-ridden experiment on live, human subjects. Whose first name is [[http://en.wikipedia.org/wiki/Josef_Mengele Josef]]. It doesn't help that his last name sounds almost like [[AdolfHitler that other Josef's boss]].
* TheDogBitesBack: [[spoiler:Martin, especially in the scene with the rude boyfriend at the beginning and later on with his mother and their skinhead neighbor.]]
** Then there's Yennie, who, in a fit of adrenaline-induced rage, [[spoiler: grabs the funnel Martin used to force-feed her earlier, [[AssShove shoves it into his ass]], before grabbing his pet centipede and inserting it into the funnel.]]
* DrivenToSuicide: [[spoiler:Katsuro.]]
* EvenEvilHasStandards: A twisted version in ''Full Sequence''. [[spoiler:Despite his obvious insanity and cruelty, Martin doesn't actually intend to kill his victims. When he does do it, or thinks he does, he becomes very upset, tries desperately to revive them, and actually cries when he fails (or thinks he did, in the case of the pregnant woman). Whether this is because, in his own twisted way, he feels bad for killing them, or is [[PragmaticVillainy just upset they can't be used in his "centipede"]] is open to interpretation.]]
* EvilOldFolks: Heiter.
* {{Expy}}: ''Full Sequence'' will feature a [[GuiltyGear mad doctor with a cardboard box, punctured with one eye-hole, on his head]].
* FanDisservice: Lindsay has some lovely breasts, but the first time you get to see them is also the first time she feeds after the operation. Did I mention she's the middle segment? In general, you've never had less fun watching topless women on all fours.
* FauxAffablyEvil: Heiter has his moments. Especially when the power cuts out and he apologizes.
* FinalGirl: [[spoiler:Yennie is implied to have survived the second film.]]
* FleshGolem
* ForceFeeding
* ForTheEvulz
* GoGoEnslavement: Sort of. Both female segments are topless for most of the movie, though the camera never focuses on this.
* GoneHorriblyRight: The Centipede...
* {{Gorn}}
* HerrDoctor, MadDoctor and MorallyAmbiguousDoctorate: Heiter.
** Dr. Sebring, Martin's psychiatrist in ''Full Sequence'', has a bit of MorallyAmbiguousDoctorate going on, himself, considering [[spoiler:he wants to rape Martin]].
* IAteWhat: Goes without saying, really.
* IdiotBall: Passed around many times, by both good and evil characters. Some examples:
** [[spoiler: Linsday, after freeing herself, dragging Jenny out of the house at a snail's pace instead of running to get help.]]
** [[spoiler: Katsuro not killing Heiter when he was down and had the chance]].
** [[spoiler: Heiter flipping out about the police's accusations, taunting them about not having a search warrant, then jokes about having a torture den in his basement. The writer clearly left no room for guessing as to what was going to happen next]].
* JackTheRipoff: In ''Full Sequence'', the first film inspires Martin to create his own Human Centipede.
* JapaneseTourist: Katsuro.
* KillEmAll
* KillTheCutie: Jenny. May or may not be the case for Lindsay.
* KneeCapping
* LargeHam: Dieter Laser is [[ChewingTheScenery clearly having a lot of fun]].
--> YOU WANT BITE? YOU CAN BITE ZIS! (whilst gesturing to brand new combat boots)
** ''[[PuttingOnTheReich Jack-boots]]'' to be precise.
* LeftHanging: Considering that there should have been some police backup the very same day (since two cops didn't report back from Creepy Guy's home), it's odd that there's no mention of Lindsay's fate.
* MadDoctor: Heiter. IN SPADES. Well, he ''is'' named [[MeaningfulName Josef]]...
* NightmareFetishist:
** In the first film, Heiter is strongly implied to be getting off when Lindsay, as the "middle" part of the centipede, is "[[{{Squick}} fed]]" by Katsuro.
** Martin, the villain of ''Full Sequence'', became sexually obsessed with the original film (which is a [[ShowWithinAShow Film Within a Film]] in the sequel's universe), and resolved to create a Human Centipede of his own.
** [[http://www.youtube.com/watch?v=VRTFsLFzDrE This Australian trailer]] for the film depicts several people's reactions to the film. Most of them are rightfully shocked... but one is shown to be masturbating.
* NoDeadBodyPoops: [[{{Squick}} Then again, considering the nature of the film, it's probably for the best.]]
* NoSocialSkills: Heiter. "Are you ''alone''? Are you ''relatives''? I don't like ''human beings''..."
* ObviouslyEvil: Heiter, good ''lord.''
* TheOtherDarrin: At the moment, Dieter Laser appears to be having a falling out and won't appear in the third film to reprise his role. As such, the role is being recast, with none other than Udo Kier himself in talks.
* ParallelPornTitles: A porn parody is in the works: ''The Human Sex-ipede''. Though the director claims that it will be more slapstick than [[NauseaFuel scat]].
** The script is actually quite funny, mostly due to the parody element.
* PlotHole: How did Heiter get the centipede out of the basement/OR if all he has is a spiral staircase? [[spoiler: This becomes quite an issue when the centipede attempts to escape]].
* RecycledInSpace: It's ''[[{{Hostel}} Hostel Part II]]''... with even more {{Squick}}!
* SerialEscalation: The first movie has [[spoiler: three people sewn together ass to mouth]] and the sequel has [[spoiler: TWELVE PEOPLE.]] The third one is slated to have [[spoiler: FIVE HUNDRED PEOPLE!!!!.]]
* ShownTheirWork: The director brought in a surgeon to consult him on how a "human centipede" would function in real life (hence the "100% medically accurate" disclaimer), including suggesting that it would be able to survive ''for years'' with an IV drip to provide fluids and nutrients. This trope may also explain why the centipede [[spoiler:doesn't last long -- almost immediately, Jenny starts dying from blood poisoning]].
* ShowWithinAShow: The first film to the second film.
* SilenceIsGolden: Martin, the second film's protagonist, never speaks any actual words and in the second half of the film dialogue is replaced by the cries and moans of the victims.
* SilentProtagonist: Martin never says a word onscreen in the sequel. He is intimated to have talked and makes phone calls offscreen (we only see him checking his messages on his phone), so he ''can'' speak, but aside from some grunts, he otherwise is [[TheVoiceless completely silent]].
* StockParody: It's well on its way to this (see the trope heading for details).
* StupidEvil: Heiter. See Idiot Ball.
* TagLine: Which doubles as a RunningGag:
** ''First Sequence'' is "100% Medically Accurate".
** ''Full Sequence'' is "[[SelfDeprecation 100% Medically Inaccurate]]".
** ''Final Sequence'' is "100% Politically Incorrect".
* TakeThatCritics: At least one reviewer sees the sequel as a TakeThat towards the critics of the first film and those who took it too seriously.
* TearsOfJoy: Heiter, [[spoiler: once... oh dear god... once it's complete]].
* TongueTrauma: See AndIMustScream.
* TooDumbToLive: Jenny & Lindsay, rather than staying on the road like any rational human being, decide to walk into the woods (at night) in the middle of nowhere Germany.
** In his review, Creator/BradJones points out that given how ObviouslyEvil Heiter was, it was incredibly stupid of the women to accept drinks from an open container from him.
** Or just driving on the flat tire since the car still ran. If they were smart, they would have paid for the insurance; so they could total it if they had to.
* TorturePorn
* TrailersAlwaysSpoil: Complete inversion for the sequel. The trailer shows absolutely NO footage of the movie, or even say what it will be like. What's the point?
** There's probably not enough showable movie. Let that sink in for a minute...
** Actually, there was a second trailer released that did show clips from the film for two minutes.
* VillainProtagonist: Heiter is the only character in the movie who gets, well, any kind of character. See [[spoiler:DecoyProtagonist]].
** And then there's Martin from ''Full Sequence''.
* VomitIndiscretionShot
* TheVoiceless: Detective Voller in ''First Sequence''.
** Martin may never speak in ''Full Sequence'', but he makes some... interesting noises.
* WoobieDestroyerOfWorlds: To some extent, Martin is this in ''Full Sequence''. [[spoiler:He was sexually abused by his father, who went to prison because of it. And his equally horrible mother actually blames Martin for her husband's arrest and treats him like garbage. His psychiatrist Dr. Sebring pretends to be his friend but actually wants to sexually take advantage of him. And most people's first reaction to him, even when he hasn't done anything, is to insult and belittle him. While there is no excuse for the actions Martin takes, it's nonetheless easy to see how all of this can combine to finally make Martin snap and lose himself in grotesque fantasy, and want to [[MoralEventHorizon enact that fantasy]] on the people who've wronged him. By the time he actually sets to work, he's so deeply involved in his mania he also targets innocents.]]
* TheWormThatWalks: Inverted.
