Cannibal Films [Wiki] are a sub genre of exploitation film made mostly by Italian filmmakers through the 1970s and 1980s. This sub genre is a collection of graphically gory movies that usually depict cannibalism by primitive, Stone-age natives deep inside the Asian or South American rain forests. Even though not all cannibal films show cannibalism on screen, all the movies are connected with the genre by stating that the tribe is cannibalistic. While cannibalism is the uniting feature of these films, the general emphasis focuses on various forms of shocking, realistic, and graphic violence, typically including torture, rape, castration and/or animal cruelty. Similarly to Mondo films, the main advertising draw of cannibal films was the promise of gore, exotic locales, and cruel behavior, and eventually became a popular aspect of Grindhouse culture. The peak of the genre’s popularity was from 1977 to 1981, a period that has come to be known as the cannibal boom.
