It's Cannibal Holocaust. That movie made me sick for real. Here's the IMDb link: http://www.imdb.com/title/tt0078935/ Content Advisory: http://www.imdb.com/title/tt0078935/parentalguide BTW, I saw the uncut/uncensored version. What about you, what's the most disturbing movie you've ever seen?
A Serbian Movie is quite sick (and pretty much pointless) and i agree with you on the Cannibal Holocaust. Both uncut versions.
I am 100% with you. I made it 10 minutes into the film and had to leave the room. Definitely regret those 10 minutes.
I haven't watched human centipede yet so I couldn't tell. But I'm interested to watch it. I have watched Hostel part 1 and 2 and compared to Cannibal Holocaust, they're nothing.
