I haven't seen this, but I saw some friends talking about this on Facebook.The Human Centipede
Apparently its a Dutch horror film about some looney surgeon who kidnaps 3 people and surgically attaches them to each other. Not like connecting them by the arm, but connecting them mouth to anus!! I'd seen the parody in South Park but never got the reference til now.
Anyway, for whatever reason, they've decided to makeThe Human Centipede 2
!! This one is sicker than the first one. This one tells the story of a guy sexually obsessed with the DVD of the first film, and pleasures himself with sandpaper while watching it!
So, he decides to kidnap 12 people and recreate the first one and does even more creepy stuff.
Apparently the Director of the first one neglected to mention the main plot until after the financial backers had paid up!! Not surprised!
