The hills have eyes 3

it is to a point...The movie was inspired by the legend of Alexander "Sawney" Bean, a Scottsman of the 15th or 16th century who reportedly headed a 40-person clan that killed and ate over 1,000 people, living in caves for 25 years before being caught and put to death. His life has inspired numerous stories and films worldwide, including The Hills Have Eyes and the British film Raw Meat, but most serious historians today don't believe that Bean ever existed that is where the story came from, if you want to belive it that is up to you
