In 1980 paranormal investigators Ed and Lorraine Warren visited the Glatzel family home in Connecticut after their 11-year-old son, David Glatzel, claimed the ghost of an angry elderly man attacked their newly acquired rental property. The man allegedly had "big black eyes, a thin face with animal features and jagged teeth, pointy ears, horns and hooves" that resembled the devil. Shortly after the encounter, the family moved into the property, and David began exhibiting strange behavior, including growling, hissing, and reciting passages in sinister voices from the Bible or Paradise lost. Convinced that their son was under demonic possession, the Glatzels contacted the Warrens, who suspected multiple possessions and tried to help David by performing three exorcisms on him.
In the third part of the Conjuring series The devil made me do it, the disturbing real-life shot of one of David's exorcisms is played over the credits. As one TikTok user put it, "You hear the devil's voice during the credits." David's mother Judy Glatzel can be heard throughout the recording, demanding that the demons leave her son alone, and David himself can be heard laughing wildly and answering in a deep, mutilated voice. The disturbing shot sheds light on the real-life events that led to the making of the film, and shows that David's parents played a much more active role in the exorcisms than portrayed on screen.
At the beginning of the film, David's exorcism is re-enacted on screen as a character records the moment and special effects are used to show his body twist into strange shapes as foam escapes from his mouth. Reports of the actual exorcism in 1980 state that David would reach for phantom hands that would choke him or scratch his skin and have seizures. While the film dramatizes much of David's experience in the alleged possession, the shot at the end of the film is a terrifying reminder of the origins of the story and the fact that our favorite horror stories are often inspired by a touch of truth.
