The Texas Chain Saw Massacre is a 1974 American slasher film directed by Tobe Hooper. It stars Marilyn Burns, Paul A. Partain, Edwin Neal, Jim Siedow and Gunnar Hansen. The film was marketed as being based on true events but its plot is largely fictional. The character of Leatherface was inspired by the crimes of murderer Ed Gein. The Texas Chain Saw Massacre was banned in several countries. It has since gained a reputation as one of the best and most influential horror films. The film is credited with originating several elements common in the slasher genre. It led to a franchise that continued the story of Leatherface and his family through sequels, prequels, a remake, comic books and video games. The film has been followed by seven other films to date, including sequels, prequels and remakes. The first sequel, The Texas Chainsaw Massacre 2 (1986), was banned in Australia for 20 years before it was released on DVD in a revised special edition in October 2006. A straight remake was released by Platinum Dunes and New Line Cinema in 2003. It was followed by a prequel, TheTexas Chainsaw. Massacre: The Beginning, in 2006. Another prequel was released exclusively to DirecTV on September 21, 2017, before receiving a wider release on video on demand and in limited theaters, simultaneously in North America on October 20, 2017.
