The film follows a group of young friends (played by Marilyn Burns, Allen Danziger, Paul A. Partain, William Vail and Teri McMinn) road-tripping by van through Texas who fall victim to a bizarre family of cannibals – including a huge masked madman known as Leatherface (Gunnar Hansen) who always has a gas-powered chain saw at the ready. The shocker originated many elements of the slasher genre that would soon explode: the use of power tools as murder weapons, a hulking faceless killer, a desolate rural setting, and the sadistic slaughter of innocent young victims.
It has been called "grisly," "sick," and "perverse,", as well as "raw," "unshakeable," and "the movie that redefined horror." It was attacked by churches, banned by governments, and acclaimed by only the bravest of critics. It stunned audiences worldwide and set a new standard in movie terror forever. Today writer-producer-director Tobe Hooper's dark, visionary tale remains unparalleled in its impact as perhaps the most frightening motion picture ever made.
