Hillside Cannibals (2006)
Hillside Cannibals is a 2006 American horror film directed by Leigh Scott and produced by The Asylum. The film bears some resemblance to The Hills Have Eyes, another film released in the same year, but its plot also incorporates elements from other films, including Cannibal Holocaust, The Texas Chainsaw Massacre and House of 1000 Corpses.
