5. Cannibal Holocaust

Banned in several countries, Cannibal Holocaust was not a movie for the casual horror fan. Real blood was used throughout (unfortunately, a number of animals – some actually shown in the movie itself – were killed to provide it), and many of the scenes are so realistic that director Ruggero Deodato was charged with murder in an Italian court for shooting what they believed to be a snuff film.

It was only when he produced the still very much alive “deceased” cast members that he was exonerated. Found-footage horror has come a long way since Cannibal Holocaust showed a documentary crew heading into the Amazon to film cannibal tribes, but this remains the bloodiest! Even all these years later, it’s difficult to sit through this movie’s most gruesome moments.
