19. The Hills Have Eyes Was Based On A True Story
While he was still on top of his game, Wes Craven directed this story about a suburban family on a road trip that is targeted by a family of savages after being stranded in the Nevada desert. While the film has gained cult-status over the years, many people are unaware of the true story behind it.
This cannibalistic classic is based on the disturbing story of Alexander "Sawney" Bean, a man-eater and clan leader who lived in Scotland during the 16th Century. Sawney’s clan was an inbred one that comprised of himself, his wife, eight sons, six daughters and plenitudes of grandsons and granddaughters.
As the tale goes, Sawney and his clan tortured, killed and cannibalized over one-thousand people in the years that they were active. They lived in caves and only ventured out after night in order to find their next meal. However, one night, the clan ambushed a couple in which the man put up a fight till a group of villagers appeared to the site of the battle. The Beans fled the scene. Eventually, King James VI was alerted and he launched a manhunt which culminated with the capture and execution of this egregious cannibal clan.
