The Texas Chainsaw Massacre is based on real events and draws inspiration from notorious serial killers like Ed Gein and Elmer Wayne Henley. The film intentionally presented itself as a true story to attract a wider audience and explore cultural and political discussions of the 1970s. While the sequels may not be directly based on true stories, they still draw inspiration from Leatherface's character and the legacy of the original film.

While Leatherface remains a fictional character, The Texas Chainsaw Massacre's true story is chillingly based on real events, including the ominous house that the cannibalistic family lived in. This all lends credence to the aura of fear that the film still embodies. The iconic slasher is still considered one of the most influential horror movies of all time and is credited with breaking new ground for the genre, including a large, hulking, faceless figure as the killer.
