Unsurprisingly banned straight after the premiere, Cannibal Holocaust became instantly infamous when the director was arrested for making a snuff film and accused of actually killing his actors on set. Of course, the title doesn't leave much to the imagination and it is surprisingly quite a violent film despite its age, to the extent that it's still banned in a few countries. The basic plot - as it exists - is that a group of American filmmakers are making a documentary about indigenous cannibal tribes in the Amazon Rainforest. One thing leads to another and the tribe pretty much eats a few of them, kills a few of them and the women are left for worse. The Face Slap Moment: Watching people impaled on wooden poles is never going to be pleasant.
