I let South Park be my filter. They did an episode on what I assume is the human centipede. (People shitting in each other's mouths wtf??) After seeing that I have no intentions of even thinking about the movie.
That South Park episode is available online on the South Park website (to those within the US). It is the first episode of the current season--HUMANCENTiPAD. Tosh.0 did a bit on it, too. It is comedy gold.
I only need to hear the premise of the film to know it's not something I want to see. "What a pleasant experience that's going to be," I don't say to myself, "I'm going to leave the cinema in high spirits after seeing this! It'll be so cathartic, I'll learn so much, I'll be moved and I'll have a fresh perspective of the world!"
It sounds like someone's trying to be a grosser Andy Warhol.
Rofl, just googled it, and found the trailer. The second I saw his drawing of this "human centipede" I thought it looked like some sort of experimental sex position.
And yeah, looks like a crappy movie with crappy actors. "WHAT... WAS.. THAT?!"
