Antropophagus (also known as Anthropophagus: The Beast, The Savage Island, and The Grim Reaper) is a 1980 Italian horror film directed by Joe D'Amato, co-written by D'Amato and George Eastman, and starring Tisa Farrow, Zora Kerova, Saverio Vallone, Serena Grandi, Margaret Mazzantini, Mark Bodin, and Eastman, who portrays a cannibal stalking tourists on a remote island.

Antropophagus has been described as having "a noted place in the annals of the escalation of gore". The film has gained cult status- if only "amongst fringe horror video audiences". It has been argued that the reason for its cult status lies in its theme of cannibalism, hence "consumption of humans", which lends itself to cult reception. The scene in which the titular man eater strangles a pregnant woman, tears out the fetus from her womb and bites into it, made it become one of the infamous "video nasties" that was prosecuted in the United Kingdom in the early 1980s, and the "controversy greatly aided its cult reputation" as well.

A pair of Germans visiting a remote Greek island go to the beach and are slaughtered by someone who emerges from the ocean.

Five travelers are preparing to tour the islands, and a woman named Julie joins them. Julie asks for a ride to an island on which some of her friends live. The only one who objects to this detour to the island (which Julie explains has only a few permanent residents and only sees tourists a few months out of the year) is Carol, whose tarot cards, the Tarocco Piemontese, convince her that something bad will happen if they go. The group sails to the island anyway. While disembarking, the pregnant Maggie hurts her ankle, so she stays behind on the boat with its owner. A man attacks the ship, ripping off the sailor's head and abducting Maggie.

The others explore the island's town, discovering it in disarray and abandoned, except for an elusive woman in black, who writes "Go Away" on a dusty window. A rotting corpse that appears to have been cannibalized is uncovered in a house, prompting everyone to rush back to the boat, which is adrift. With no other options, the group goes to the house owned by Julie's friends, where they find the family's blind daughter, Henriette. After wounding Daniel in a panic, Henriette calms down and rants about there being a madman who smells of blood prowling the island.

Andy and Arnold search the town for antibiotics to stop Daniel's wound from getting infected. Carol walks in on Daniel flirting with Julie and goes into hysterics, running off into the night. Julie goes after Carol but loses her and meets up with Andy and Arnold. The disfigured killer breaks into the house and rips Daniel's throat out, but leaves Henriette alone and flees as the others return. Everyone treks through the island in the morning and finds a mansion belonging to Klaus Wortman. Julie mentions that she read that Klaus, his wife, and their child are assumed dead, having been shipwrecked, a tragedy which caused Klaus' sister Ruth to become unhinged. Ruth (the woman in black from earlier) watches the group enter the building, comforts the sleeping Carol, and hangs herself.

After Carol wakes up, Andy and Arnold look out a window and see that the boat has drifted close to shore. The two men go to secure the vessel, and Julie finds a partially destroyed journal among the objects in the mansion. It reveals that the killer is Klaus and that the bodies of all of Klaus' victims are in a hidden room. Andy and Arnold split up, and the latter reaches an abandoned church, where he finds Maggie and is confronted by Klaus. Klaus has a flashback that reveals he and his family were stranded in a raft after being shipwrecked and that Klaus accidentally stabbed his wife while trying to convince her that they should eat the body of their dead son to survive. Klaus then ate his wife and son's corpses, driving him insane. Klaus regains his composure, stabs Arnold, then strangles Maggie to death. As Arnold slowly dies, he watches in horror as Klaus rips out and eats Maggie's unborn child.

Julie uncovers the room where Klaus' victims are at the mansion and skims through another diary she finds. Carol stumbles into the chamber and drops dead from a slit throat. Klaus then attacks Julie, who locks herself and Henriette in the attic after a short chase. Klaus breaks through the ceiling and kills Henriette, and is then knocked off the roof by Julie and falls into a well. When Julie peers down the well, Klaus attacks her, but she is saved when Andy appears and stabs Klaus in the stomach with a pickaxe, causing the cannibal's intestines to spill out. As a last dying act, Klaus gnaws on his innards, staring at Andy, while Julie looks at Klaus in horror; Klaus then falls over and dies. The film ends with Andy and Julie standing over Klaus' body, staring at each other in shock.
