Trivia: When Larry tries to prove that they were married before, Ellen asks him to name the song playing on the radio when she was ticketed as a teenager. The song was "Give Me Some Loving," a song done many times by the Blues Brothers, initially starring Jim Belushi, but a role James took on after Jim's death.
Trivia: The other good-guy doll "Tommy" was allegedly named after Tom Holland, director of the first film. Holland and series creator Don Mancini supposedly didn't get on very well behind-the-scenes, and it's been suggested that Chucky breaking and then burying the Tommy doll was a subtle jab at him.
Trivia: Even though the characters themselves are constantly confused as to which of them is Rosencrantz and which is Guildenstern, there is a way for the audience to make sure: In the scenes where they take part in "Hamlet" and interact with others, Gary Oldman always delivers the lines of Rosencrantz, and Tim Roth always delivers Guildenstern's.
Trivia: Glenn Close plays Mel Gibson's mother in the movie, even though in real life she's only 9 years older than him.
Trivia: Miriam Margolyes plays Kevin Kline's mother in the film, even though in real life she's only six years older than Kline.
Trivia: Pamela Poitier, who plays the role of Nurse Satler, is the daughter of the film's director, Sidney Poitier.
Trivia: Shirley MacLaine (born 1934) is only fifteen years older than Meryl Streep (born 1949), who plays her daughter.
Trivia: As an in-joke, Brian Hope and Charlie McManus are both credited as playing the flight attendants in the ending credits.
Trivia: Richard Gere and Andy Garcia did not get along during the filming, and much of their fighting in the elevator sequence is real.
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: The scene where Quigley triggers a booby trap by swinging his rifle from horseback, at full gallop, whilst holding it by the tip of the barrel with one hand, was only possible because an alternate aluminum barrel was created for that scene.
Trivia: Before Damon Wayans was cast as Eddie, Richard Pryor was offered the voice role, but had to decline due to ill health.
Trivia: When the agent pulls from the computer record Richard's file, an alias listed is "David Putnam - Columbia Pictures", employed from 06/04/1973 to 02/01/1975. That's an obvious reference to producer David Puttnam (two Ts), who had a brief stint as head of Columbia Pictures in 1986-87, not making many friends in the then Coca-Cola owned production company.
