The Exorcist III (1990)

Continuity mistake: When the nurse is wrapping a tensor bandage (also known as an Ace bandage) around Kinderman's hand and wrist, the way the bandage is wrapped changes between shots.

Continuity mistake: When Kinderman connects the murder victims to the case in the first movie, he says that the African American kid was the son of the the woman that figured out Regan was speaking backward English. Only when you watch the first movie, the person that figures out what she's speaking is a man that is Caucasian.

Trivia: Director William Peter Blatty wanted to title the film "Legion" after his novel the script was based on, while the studio (understandably) wanted to call it "The Exorcist III" for brand-recognition reasons. Blatty absolutely hated "Exorcist II: The Heretic" and felt that the title "The Exorcist III" would suggest this movie followed that one, so he countered by suggesting they title the film "The Exorcist 1990." The studio eventually won out and went with "The Exorcist III."

Trivia: At one point, the Gemini Killer says the line "it's child's play," and the film cuts to a little red-haired kid. This is a cute little in-joke, as the Gemini Killer is played by Brad Dourif, who voices the killer-doll Chucky (a doll with red hair) in the "Child's Play" horror movie series.

Trivia: Director William Peter Blatty's original cut of the film was believed to be lost, as the studio could not locate the footage. However, an old videotape containing much of the lost footage was found in 2016, and Blatty was able to splice the VHS-quality footage into the movie to assemble an impromptu "director's cut" shortly before his death. The "director's cut" was finally released on Blu-Ray through boutique company Shout Factory in late 2016.

Father Dyer: May the schwartz be with you.

Patient X: I still hear from her occasionally, screaming. I think the dead should shut up, unless there's something to say.

The Gemini Killer: Catatonics are so easy to possess.
