In Eli Roth’s latest horror flick, a group of young environmentalists heads to the rain forest in an attempt to “save it,†only to find themselves plane-wrecked and captured by a local tribe. Considering that the movie is based on Ruggero Deodato’s 1980 Cannibal Holocaust — which Roth actually screened for an Amazonian village back in 2012 — you can pretty much imagine what happens next. See a mostly terrifying preview below and catch the whole gory tale when the film comes out in early September.
