6. THE THAI TRIBE IN THE MAN FROM DEEP RIVER (1972)
If you’ve ever vomited profusely while watching a trashy 1970s Italian horror flick set in a jungle, you’ve got Umberto Lenzi, director of the seminal The Man From Deep River, to thank. Considered as the first popular example of Italy’s cannibal sub-genre, Lenzi’s pic follows a British photographer on an assignment within a Thai rainforest; there, he gets in deep with a native tribe that’s at war with an even dirtier group of cannibals known as the Kuru. While it’s not as important to film’s history as The Jazz Singer (the first feature-length movie with dialogue), The Man From Deep River is an important trend-setter for any guy who collects old horror movie posters, wears Cannibal Holocaust T-shirts, and generally scares off women as soon they first step foot in his bedroom.
