20 Most Extreme Horror Films Of All Time

As Umberto Lenzi’s follow-up to his cannibal “classic” Eaten Alive, Cannibal Ferox (aka Make Them Die Slowly) takes the madness up a few thousand notches. As a fairly blatant rip-off of Cannibal Holocaust, Cannibal Ferox may not trump its influencer in the groundbreaking department, but it certainly takes things further in terms of extremity (even if the violence is ultimately taken to cartoonish levels).

Upon its release, the film’s distributor claimed it was “the most violent film ever made.” The film was also claimed to have been “banned in 31 countries,” some of which lifted their bans only recently. The story follows three friends out to disprove cannibalism and establish that it is simply a myth. As you could probably guess, things don't go according to plan. Murder and mayhem (and yes, cannibalism) ensue.

Degenerate, wicked and depraved; fainthearted individuals will surely turn away in utter disgust and revulsion. However, anybody who is able to throw their political correctness out the window will surely enjoy this sick symphony of sheer cruelty.
