Cannibal Holocaust * (1980)

IMDB Link = http://www.imdb.com/title/tt0078935/

This cult movie is banned in most countries. For a good reason. This is the goriest, most repulsive and sickening movie I have ever seen. It features cannibalism and (real) animal killings. No director would make a movie like this today. As horrible it is to watch it, credit must be given to the director for making a bold movie, completely ignoring the timid morality and hypocrisy of film-making ethics.
