'Cannibal Holocaust'

If you want to go into the jungle to document a tribe of cannibals, you have to be prepared for the possibility that -- well, you could be eaten. Unfortunately, the camera crew in 1980's 'Cannibal Holocaust' did not take this into account. After they go missing in the Amazon, a rescue team is sent after them, only to discover human bones and a set of film reels. When they play the found footage, viewers are treated to some of the goriest scenes in movie history including the murder of defenseless animals. ('Cannibal Holocaust' was initially banned in several countries due to its graphic nature.)

So what ended up happening to the missing crew? Well, apparently they decided to terrorize the local tribe in order to "make their film better." That did not sit well with the cannibals, so they did the one thing they knew best -- harvest the filmmakers and eat their remains.
