Hey girls! Hey mister! What an insane world we live in.
It is about two girls visiting Germany, and are driving somewhere, and their car gets a flat tire. They end up exiting the car and looking around for help. They spot a near by house, and knock on the door. The person who answers it is a very strange man, who acts susp*cious constantly, but the two girls are desperate, so they stick with him and ask to call a tow truck. He drugs them, and they wake up in a hospital-like area, and this is where the strange man introduces himself as Dr. Heiter, and tells them he will sew them together, "mouth-to-anus". But you probably already knew this story line. Pretty disgusting, huh? Well, viewers may be comforted by the fact that very little violence is shown, and absolutely no excrement. The Human Centipede (First Sequence) is more of a psychological mind-f*ck. You put yourself in the situation, and then you feel sick. But with that said, the movie is still fairly tame. Just wait until Human Centipede II (Full Sequence) and 2013's Human Centipede III (Final Sequence).
Dieter Laser is very perfect as Dr. Heiter. They could not have gotten someone else better. His voice acting is subtly comical, yet demented at the same time. As for the two female leads, while I have seen worse in independent horror films, they still leave something to be desired. In the beginning, before they get sewed together, their voice acting is not very good, and they act almost annoying.
Tom Six is the director. He has not done much of anything, with only a few titles under his belt. He is mostly known for this "Centi-series" he's got going. But Tom Six is a great director because he really knows what he wants. He does not want to make a complicated, drawn out film. He wants to make a shocking piece of cinema. He has no intentions of making the next Serbian FIlm, just a movie that is flat out gory and disturbing. He stated that this was his build up to the sequel. And the sequel is a build up to the third film.
The Human Centipede is not a film that should be sat down and analyzed closely. While maybe a little bit more time could have been spent on it, it still accomplishes it's goal. Being the first film in horror's most disturbing and disgusting series.
