10 Horror Movies That Left Out The True Horrific Ending

10. The Texas Chain Saw Massacre

The original 1974 Texas Chain Saw Massacre shares some of its DNA with Alfred Hitchcock's Psycho and Jonathan Demme's The Silence of the Lambs.

All three films take some inspiration from Ed Gein, a real-life killer with a habit of making trinkets out of dead people's bones and skin. Sound familiar?

Gein was not the only real-life figure that writers Tobe Hooper and Kim Henkel borrowed from in this movie. In an interview with Texas Monthly, Henkel revealed that another genuine criminal was part of Leatherface's character.

Elmer Wayne Henley was an accomplice to an older serial killer in the '70s, helping him lure his victims back to his home.

As Henkel says, "I saw some news report where Elmer Wayne said, 'I did these crimes, and I'm gonna stand up and take it like a man'. Well, that struck me as interesting, that he had this conventional morality at that point."

The disparity between Henley's utterly monstrous actions and his apparent moral compass is extremely disturbing. How can one man commit such heinous acts and own up to them with such an apparent lack of guilt?

It's unsettling, and a vital detail missing from the first Massacre film.
