In the third movie of "The Conjuring" franchise, "The Devil Made Me Do It," paranormal investigators Ed and Lorraine Warren, played by Patrick Wilson and Vera Farmiga respectively, take on the Arne Cheyenne Johnson case.
It's known as the first-ever US court case in which the defense was that the murder suspect was possessed by a demon.
Out of the countless scares in the movie, a memorable one is when a young boy named David Glatzel (Julian Hilliard) encounters a waterbed — and a demon.
According to director Michael Chaves ("The Curse of La Llorona"), the scene is inspired by a true event.
The real-life Warrens took part in Glatzel's exorcism in the early 1980s. Following that, the demon in Glatzel's body ended up inside Johnson's, according to court testimony. A bed in the house that the Glatzel family had moved into is believed to be the cause of how David came to host the demon in the first place.
"The Glatzel family moved into this house and the previous owner had left a bed there," Chaves told Insider. "There was this really strange stain on the bed, and it's believed that was the origin of the possession."
Chaves said "The Devil Made Me Do It" screenwriter David Leslie Johnson-McGoldrick ran with that and came up with the movie having Glatzel encountering a waterbed that was left behind when his family moved into a house.
"I thought it was a stroke of genius," Chaves said. "Waterbeds are from such a specific time, so I felt the discovery of that and playfulness, there could be something great there."
The result is a terrifying discovery by young Glatzel.
Here's an exclusive look at the waterbed scene:
The movie opens in theaters and is available on HBO Max June 4.
