The Human Centipede 2 (Full Sequence) is a 2011 psychological body horror film[4] written, directed, and co-produced by Tom Six.

In the tollbooth of a parking garage in East London, Martin Lomax is watching The Human Centipede (First Sequence), a film he is obsessed with, on his laptop.

Martin acquires a dingy warehouse after killing the owner and landlord, and begins abducting people to use for a twelve-person human centipede.

His victims include a young couple, a man and his pregnant wife, and two drunk girls who catch Martin masturbating with sandpaper.

After killing her by bludgeoning her head with a crowbar, Martin then lures his detested neighbour, Dick, to the scene, before shooting and kidnapping him.

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.

Martin experiments by having his centipede walk around and force-feeds Ashlynn cream-of-mushroom soup using the funnel and tube when she refuses to eat from the dog bowl.

As he hesitates to kill Ashlynn, she punches him in the crotch and shoves the funnel into his rectum, before dropping his pet centipede into it.

The scene cuts back to the tollbooth with Martin rewatching the credits of The Human Centipede, leaving the audience to wonder whether the events even happened.

Director Tom Six stated in 2010 that he was working on a sequel to The Human Centipede (First Sequence), as well as a possible third film depending upon its success.

[9] Additionally, Ashley C. Williams, whose character was left alive at the end of First Sequence, stated in September 2010 that she was shooting a horror film in Britain, which led to speculation from FEARnet that she is reprising her role of Lindsay.

[14] A teaser trailer was released on 24 September, in which Six introduced Martin, a man wearing a cardboard box over his head, as the new doctor.

A full-colour version of the film was released for the first time in the United States on 27 October 2015, exclusively on The Human Centipede: The Complete Sequence Blu-ray set.

[20] The Board stated that they had considered First Sequence to be "undoubtedly tasteless and disgusting",[20] but deemed it acceptable for release because the "centipede" was the product of a "revolting medical experiment".

[20] By contrast, the BBFC report on Full Sequence stated that the film's content was too extreme for an 18 certificate and was "sexually violent, and potentially obscene".

[20] The board members felt that the centipede of Full Sequence existed purely as "the object of the protagonist's depraved sexual fantasy".

[25]The sales director of Eureka Entertainment supported the decision, stating: We are really pleased that after nearly four months of detailed discussion and debate, we have been able to reach an agreement with the BBFC and to produce a very viable cut of the film which will both excite and challenge its fans.

[27] Several groups and individuals, including FamilyVoice Australia,[28] Collective Shout[29] and Cardinal George Pell, the Archbishop of Sydney,[30] welcomed the decision.

[34] However, in April 2012, the DVD version was classified as "objectionable" (banned) by the New Zealand Office of Film & Literature Classification.

The site's consensus reads: "The Human Centipede II (Full Sequence) attempts to weave in social commentary but as the movie wears on, it loses its ability to repulse and shock and ends up obnoxious and annoying.

Miska added that he "found it an intensely engaging and absolutely hilarious meta experience that gets its point across with flying colors", but was critical of the script's lack of depth.

[39] Entertainment Weekly writer Owen Gleiberman gave the film a B+ rating, stating that viewers "may feel gripped by the horror of what you're seeing and the terror of what's coming".

"[40] Writing in the New York Post, V. A. Musetto gave the film 3 out of 4 and said Full Sequence "is sick, disgusting and vile.

To some degree, yes; it's designed to turn the tables on its own gore-hungry fans by depicting a fictionalized version of one of their own so revolting they think twice about their twisted tendencies.

Robert Koehler, writing for Variety, found the gore so excessive that he termed it a form of lazy filmmaking.

The problem, unfortunately, is that director Tom Six is like a child – attempting to make a profound statement but unable to get it out eloquently or even in anything not resembling a whimper or a groan most of the time ... Who would have guessed?

Six stated that the third film would again be very different from the previous entry, but would also start with its ending, making the trilogy similar to a centipede.

Around late 2012, actor Dieter Laser and Six ended their legal battle about creative differences, which had been ongoing since March 2012.

Six had said that the film would star a "big American celebrity", have "a storyline that nobody would expect", and feature a centipede consisting of 500+ people.

Other cast members include former pornographic actress Bree Olson, Robert LaSardo, and Tommy "Tiny" Lister, Jr.
