If last month's red band trailer for The Human Centipede 3 was too much for your to stomach, then perhaps IFC Midnight's all-ages trailer is more up your alley. Of course, given the nature of this vile and "100% politically incorrect" sequel, this trailer may still make you a bit squeamish, but it's not nearly as graphic as the age-restricted sneak peek. We also learn about writer-director Tom Six's cameo as himself, as he is brought in to "consult" with a prison that wants to use his "medically accurate" Human Centipede model on their inmates.

Bully prison warden Bill Boss (The Human Centipede (First Sequence)'s Dieter Laser) has a lot of problems; prison riots, medical costs, staff turnover, but foremost he is unable to get the respect he thinks he deserves from his inmates and the state Governor (Eric Roberts). He constantly fails in experimenting with different ideas for the ideal punishment to get the inmates in line, which drives him completely insane. Under threats of termination by the Governor, his loyal right hand man Dwight (The Human Centipede II (Full Sequence)'s Laurence R. Harvey) comes up with a brilliant idea. An idea based on the notorious Human Centipede movies, that will literally and figuratively get the inmates on their knees, creating the ultimate punishment and deterrent for anyone considering a life of crime.

Tommy Lister, Robert LaSardo and Bree Olson co-star in The Human Centipede Part 3 (Final Sequence), Tom Six's final installment of his Human Centipede trilogy, which will be released in theaters and on VOD formats May 22. Does this 500-person Human Centipede intrigue you enough to check out this sequel? Or is the concept too disgusting to comprehend?
