Widely considered to be the creepiest movie of the ‘70s, The Exorcist also apparently had the creepiest movie set, too. Many of the stories that surround the film aren’t confirmed, though, because some people associated with production discount them while others affirm them. But for the sake of cinematic folklore, we’re going with it.
For starters, nine people died during the film's production; you’d think after the fifth person, they might have been inclined to just say “shut it down” and go home. Apparently there was a fire that destroyed the set, and during screenings of the film, people had strange reactions such as fainting and vomiting. One woman miscarried. Death tolls rose in Georgetown (which is where the movie is set) after the movie was released.
Well, "disturbing" doesn't begin to cover it.
