Eaten Alive!

Umberto Lenzi cynically recycles footage from earlier cannibal films, including his own and Deodato's, into a new story about a woman searching for her sister in a jungle death cult modelled on Jonestown. It is a patchwork built to cash in, and it shows.

The real animal killings and gore are present, some of it literally lifted from other movies, and the film is the point at which the cycle is visibly eating itself. Only the Jonestown framing gives it any distinguishing feature.

Bottom-tier cannibal cinema, assembled from spare parts. Same warnings apply.
