In 1973, a movie was released that terrified the world.
Four years later, a book was released that is now thought to have been inspired by that movie. The book?
At the time, though, the story was extremely gripping. A couple named George and Kathy Lutz said they moved into a house that was so haunted, it tormented them. Just over a year earlier, a man killed six members of his family in the house (that part is true).
The murderer said he was possessed. The Lutzes said Exorcist-like events happened while they were in the house, as well.
The success of both the movie and book led people to investigate whether the facts were true. While the Lutzes vehemently denied they'd fabricated the events in the house, Kathy Lutz's son has revealed many of the events in the book were fake. While he says some strange things happened in the house, much of what was described in the book was sheer sensationalism.
Here's an episode of 30 Odd Minutes featuring Christopher Lutz.
