In Eli Roth's 'The Green Inferno,' a well-meaning group of activists travel to a rainforest in South America. Their protest mission accomplished, they head home -- only to crash-land on territory belonging to a tribe of native peoples who are looking for a little more, er, variety in their meat dishes. The horror film, an homage to the notoriously banned ‘Cannibal Holocaust,’ introduces a whole new group of movie cannibals to a stomach-churning list of frightening flesh eaters.
