The Terrifying Subliminal Image Hidden in The Exorcist

When director William Friedkin’s The Exorcist opened in 1973, it quickly became one of the most critically acclaimed and financially successful horror films of all time. Unlike the slasher movie antagonists of the 1980s, Friedkin’s adaptation of William Peter Blatty’s novel was uninterested in winking at the audience. He was interested only in terrifying them, which he did to unprecedented effect.

Local newscasts reported viewers fainting, vomiting, and fleeing the theater, shaken by the film’s explicit depiction of a young girl named Regan MacNeil (Linda Blair) possessed by demons and exhibiting blasphemous behavior. But it’s possible they may have been just as unsettled by what Friedkin decided to insert into the film surreptitiously—a frightening, subliminal image that was funneled straight into the audience’s subconscious.

According to The Exorcist fan site, the white-faced demon seen below briefly flashes onscreen at 45 minutes and one second into the film, during a dream sequence featuring Father Karras, the priest charged with drawing malevolent spirits from Regan’s body:

In an extended cut of the film, the face is seen earlier: at 31 minutes and 29 seconds in, when Regan is undergoing a medical examination. In the same edit, marketed as The Version You’ve Never Seen for home video, the demon materializes once more at 56 minutes and three seconds in:

In the theatrical version, the second and most prominent shot of the face comes one hour, 43 minutes, and 13 seconds in, when Regan is being exorcised:

The fleeting shots were part of Friedkin’s strategy to unnerve moviegoers using both visuals and sounds that he felt stood the best chance of creating an uneasy atmosphere. The face was intended to represent one of the demons inhabiting Regan and appears for roughly an eighth of a second each time.

Interviewed by Entertainment Weekly about the technique in 2012, Friedkin lamented that home video gave most of his secrets away. “You couldn’t catch it before VHS,” he said “And now you can stop the DVD and stare at it.” Not that you'd want to.
