20 Most Extreme Horror Films Of All Time

In 2010 Dutch filmmaker Tom Six unleashed The Human Centipede onto the masses, giving genre fans everywhere the original idea of a madcap surgeon who stitches three people together, ass to mouth. The plot and title alone were enough to cast a notorious reputation upon the movie, but it’s sicker in concept than presentation. In the first Centipede, not a whole lot is actually shown.

However, the film’s sequel takes the bad taste concept of its predecessor and expands it in an extraordinarily grotesque manner. Enter Martin, a squat and clammy night-shift security guard who is hopelessly enveloped within the mythos of the film The Human Centipede. Obsessed with the colonically unifying efforts of the psychotic surgeon of the film, Martin dreams of the construction of a centipede of his own. He is ambitious in his scope and knocks out twelve people – stapling their mouths to each other’s backsides; creating a truly hellish creature.

Needless to say, this film is quite nauseating. Though, the absolute pinnacle of disgusting scenes in the film is when Martin injects each of the “components” of the centipede with laxatives and they all explosively defecate into each other’s mouths. The look of pure glee on Martin's face... priceless.
