Director, Tobe Hooper and co-writer of the original The Texas Chain Saw Massacre, Kim Henkel originally had an idea for a sequel that would feature an entire town of cannibals, and also be a satire of the film Motel Hell, which itself was a satire of the original Texas Chainsaw Massacre. The title of that sequel was to be 'Beyond The Valley Of The Texas Chainsaw Massacre', but the studio forced considerable changes to be made to the screenplay, even hiring a new screenwriter, and the result of those changes are what became Texas Chainsaw Massacre part 2.
Out of all the sequels and remakes, this is the only film which follows the same time-line as the original film. All of the others have no reference in their screen stories to the events in the original film The Texas Chain Saw Massacre.
Throughout the film, many references are made to the "Red River Rivalry" or "Red River Shootout" in regards to the football game going on during the film. This was not invented for the film. As any avid college football fan can tell you, the "Red River Rivalry" is the common name for the animosity between the University of Oklahoma and the University of Texas. The film takes place during OU vs. Texas weekend.
Caroline Williams wanted to make a strong impression at her audition. When she was called in, she went to the end of the hallway and ran screaming into the room, where she pulled Tobe Hooper and L.M. Kit Carson out of their seats and used the chairs to barricade the door before she began her scene.
A release in West Germany in 1986 was not possible because the film was banned before the film could be released to theaters. In 2012, Turbine Medien acquired the rights to the film and has now begun the process of getting the banishment revoked (something they successfully did for the first TCM).
