Antropophagus

Anthropophagous: The Beast (Italy, 1980)
Director: Joe D'Amato
Starring: Tisa Farrow, George Eastman, Saverio Vallone.

A group of tourists arrive on a small Greek island, only to find it almost completely deserted. It seems that the only person still alive there is a blind girl who does not know what has happened to the rest of the town, but is terrified of a woman who she describes as smelling of blood.
As members of the group disappear or are murdered by a mysterious man, the survivors search for clues as to what is going on. They find a diary, which tells the story of a man who was shipwrecked with his wife and child. In order to survive, the man was forced to eat his dead family. This act drove him insane and he went on to slaughter the rest of the island's inhabitants.
In the film's most notorious scene, the killer strangles a pregnant woman while pulling the fetus, which was actually a skinned rabbit without ears and covered in blood, from between her legs. The effect proved so convincing that the filmmakers were attacked and questioned as to whether they really extracted a human fetus from its mother's womb. In the end, the killer is dispatched by means of a pick axe to the stomach, but before he dies he attempts to devour himself, chewing violently on his own intestines before finally dying.
