The most impressive thing about The Human Centipede is it's ability to provoke people in theory alone. It's the kind of film whose mere plot description - three poor souls who have their kneecaps surgically removed are sewn together in a mouth-to-anus chain - bothers people. Say what you will about the actual film, but I tip my hat to any horror movie that riles people up before they even see it.
Well now with The Human Centipede 2: Full Sequence a little over a month away from release, Tom Six is once again prodding people without actually showing them anything. The Australian distributor of the film has released a teaser trailer for it, and while we don't actually see any footage from the film in it, it does a pretty great job of selling the sick. Check it out above.
Thanks to @NoahPhex for sending this our way.
