described as "the ultimate pro-vegetarian film" due to its animal rights themes. In a video essay, film critic Rob Ager describes the irony in humans' being slaughtered for meat, putting humans in the position of being slaughtered like farm animals. Director Tobe Hooper has confirmed that "it's a film about meat" and even gave up meat while making the film, saying, "In a way I thought the heart of the film was about meat; it’s about the chain of life and killing sentient beings." Writer-director Guillermo del Toro became a vegetarian for a time after seeing the film. Post-release The Texas Chain Saw Massacre has appeared on various home video formats. In the US, it was first released on videotape and CED in the early 1980s by Wizard Video and Vestron Video. The British Board of Film Classification had long since refused a certification for the uncut theatrical version and in 1984 they also refused to certify it for home video, amid a moral panic surrounding "video nasties".

After a screening in the Directors' Fortnight section of the 2014 Cannes Film Festival, this was also released on DVD and Blu-ray worldwide.

In the game, the player assumes the role of Leatherface and attempts to murder trespassers while avoiding obstacles such as fences and cow skulls.
