Italian horror maestro Umberto Lenzi takes the form to new heights with this classic that has a team of would-be anthropologists discovering a tribe of cannibals being exploited by a cocaine cartel in the jungles of Colombia. Filmed on location in South America and New York, this cult favorite boasts camerawork that lingers lovingly on the carnage as scenes of evisceration, emasculation, eyeball gouging and more play out.
