The Hills Have Eyes (1977)

The Hills Have Eyes is directed by horror pioneer Wes Craven, and it’s about a vacationing family who gets stranded in a desert and falls prey to a pack of blood-thirsty cannibals.

While the premise sounds stranger than fiction, this story is based on the real-life Sawney Bean Cave Clan of Scotland, who were a group of cannibals that killed over 1,000 people in the 16th century.
