The Hills Have Eyes is based on the Sawney Bean story. In 15th and 16th-century Scotland, Bean left home and took to the coastal caves with a woman where they lived for a number of years and had 14 children. The clan ambushed innocent passersby and murdered them for food. The family was hunted and brought to trial. At that time, they numbered 48, most of them the product of incest. The entire family was executed for the murder and cannibalization of over 1,000 people.
