Roth's gory tribute to the likes of Italian gonzo directors Ruggero Deodato (Cannibal Holocaust) and Umberto Lenzi (Cannibal Ferox), sees a group of American student activists head deep into the jungles of Peru fired up by the idea of protecting the rainforest and the natives who live within. A noble sentiment, but one that proves to be their undoing when their small plane crashes deep within the jungle and they are soon discovered by an indigenous tribe that have never seen outsiders.
The natives prepare a warm welcome for the new arrivals, in that they start fires for cooking pots and conjure up all manner of terrible tortures for our travellers, some of whom try to escape.
"We travelled deep into the Amazon, like Aguirre," he told Empire last year. "We found a village with no electricity or running water, where most of the young children and the elders had never seen a movie or television before. We brought a generator and showed them [Deodato's infamous] Cannibal Holocaust (1980) to see how badly it would freak them out, but they laughed and thought it was the funniest thing they'd ever seen, and after that about 80 people signed up to be in the movie!"
Green Inferno is finally set to arrive on 25 September.
