Martin acquires a dingy warehouse after killing the owner and lessor, and begins abducting people to use for a twelve-person human centipede. His victims include, but are not limited to: Ian, an aggressive young man and his girlfriend Kim (who Martin is attracted to); Alan, a businessman; Tim, a rich man and his pregnant wife Rachel; Valerie and Karrie, two drunk girls who catch Martin masturbating with sandpaper; and a man named Greg.
Martin's mother finds and destroys his scrapbook in disgust after unsuccessfully attempting a murder-suicide. When Mrs. Lomax attempts to dispose of his centipede, Martin kills her by bludgeoning her head with a crowbar. He then lures his detested neighbour, Dick, to the scene, before shooting and kidnapping him.
Martin assembles his "centipede". Following his notes and sketches from The Human Centipede, Martin severs the ligaments in each person's knees to prevent them from fleeing and uses a hammer to knock out their teeth. However, Martin cuts into the buttocks of Alan too deeply, causing him to bleed to death. Instead of surgical tools, he uses a staple gun and duct tape to attach each person's lips to the next person's buttocks. During the assembly, Rachel (who was planned to be the front of the centipede in sympathy for her pregnancy) is presumed dead; Martin places her in the corner. Martin's "human centipede" is ultimately ten people long with Ashlynn in front.
Roger Ebert, of the Chicago Sun-Times, who did not assign a star rating to the original, gave this film zero stars on review, calling it "reprehensible, dismaying, ugly, artless and an affront to any notion, however remote, of human decency." He would later name it the worst movie of 2011.
The Human Centipede (First Sequence) is a 2009 Dutch independent body horror film written, directed and co-produced by Tom Six. The film concerns a deranged German surgeon who kidnaps three tourists and conjoins them surgically, mouth to anus, forming the eponymous "human centipede". It stars Dieter Laser as Josef Heiter, the creator of the centipede; and Ashley C. Williams, Ashlynn Yennie, and Akihiro Kitamura as Heiter's victims.
The Human Centipede contains relatively few gory images; little of the surgical procedure is depicted directly, no excrement is shown on screen, and according to Kim Newman in Empire, it is "never quite as outrageous as it threatens to be." Six stated that he wanted the film to be as authentic as possible and claimed to have consulted a Dutch surgeon during the creation and filming process, resulting in the film being "100% medically accurate." Six said that the surgeon initially wanted nothing to do with his film, as he felt Six was "crazy" and the idea had "nothing to do with medical science." However, the surgeon changed his mind and decided that he liked the idea, and so came up with a method of creating a human centipede. Six has claimed that the central and rear members of the centipede could survive for years by supplementing their diet with an IV drip. The special effects team was led by Rob and Erik Hillenbrink, father and son. They designed the final composition of the centipede from sketches provided by the consulting surgeon. The actors who made up the centipede wore hardened underwear, compared by Yennie to shorts, which had a rubber grip for the actors to wear, and for the actor behind to bite, creating the illusion of the mouth-to-anus connection. Six kept secret how the centipede would be formed as long as possible, and Yennie claimed that even her make-up artist did not know, asking Yennie what kind of "suit" the actors would be wearing.
Critics and a doctor have dismissed Six's claim that the film was "100 percent medically accurate" as "ludicrous" and "rubbish". Dr John Cameron, speaking to TV3 News in New Zealand, gave an interview about the feasibility of a human centipede, stating how he believed it would be difficult for a join between different people to heal and form a connection, and how the centipede would quickly die from lack of nutrition. John Martin, a former Hollywood film executive and CEO of Alamo Drafthouse Cinemas, said Six's claims of 100 percent medical accuracy should be viewed with reference to the kind of shock gimmicks that film producers had long used to attract attention. Martin compared Six's claims to those of Kroger Babb and William Castle, who had also made "grand promises" about what they were putting on screen, in a bid to lure audiences.
When Tom Six began creating the Human Centipede sequels, he envisioned a trilogy that works as a "movie centipede". Each sequel opens with the ending of the previous film, as the events of that film influence said sequel. Although every film works as a standalone movie, they can all be connected to form a single 4.5-hour-long film.
The plot of Full Sequence involves a man who, after becoming sexually obsessed with a DVD recording of First Sequence, decides to create his own human centipede. The film had been planned for a DVD release in the United Kingdom. However, upon submitting the film to the BBFC for classification, the film was rejected due to content that was "sexually violent and potentially obscene". The BBFC's report criticised the film as making "little attempt to portray any of the victims in the film as anything other than objects to be brutalised, degraded and mutilated for the amusement and arousal of the central character, as well as for the pleasure of the audience," and that the film was potentially in breach of the Obscene Publications Act, meaning its distribution in the UK would be illegal. Bounty Films, the UK distributor, appealed the decision, and the film was eventually passed with an 18 certificate in October 2011. To achieve the 18 rating, thirty-two cuts were made from the film, removing two minutes and thirty-seven seconds from the original version.
A number of parodies of the film have been made. A pornographic parody, directed by Lee Roy Myers and titled The Human Sexipede, was released in September 2010. It starred Tom Byron as Heiter, who joined three people mouth-to-genitals. The South Park episode "HUMANCENTiPAD" saw character Kyle Broflovski unwittingly agreeing to become a part of a "Human CENTiPAD" after failing to read the full details of an Apple user license agreement. The website Funny or Die featured a sketch where the freed victims of a human centipede, now separated, but scarred physically and mentally, argue at a survivors' meeting. The Human Centipede 3 (Final Sequence) actress Bree Olson starred in a parody of the franchise that was directed by Graham Rich. 2b1af7f3a8
