Cannibal Holocaust (1980) | Cannibal Holocaust is one of the earliest examples of found footage horror, and it still leaves a more lasting impression than almost all of the modern iterations. That’s because it feels painfully real — so real, in fact, that director Ruggero Deodato was put on trial for making what appeared to be a snuff film. Warning: The violence against animals, including an ill-fated turtle, is almost certainly not faked.
