Trivia: Writer Bruce Rubin's mother has a cameo in this movie. She portrays the nun who collapses after seeing how much money is on the check.
Trivia: Have a close look at the Predator's trophy collection on his spaceship. Taking pride of place is a skull from the creature in the Alien movies. (01:33:05)
Trivia: Robert Duvall was asked to reprise his role as Tom Hagen, but an agreement couldn't be made on the price.
Trivia: Paramount Studios essentially rented a US submarine to be in the movie. The USS Houston (SSN 713) played the USS Dallas and the surface scenes were filmed off of Long Beach, CA and Port Angelas, WA. Two crewmembers off the Houston were actually given very small speaking parts in the movie.
Trivia: Director Rob Reiner makes a cameo as the helicopter pilot helping Buster search for Paul's car.
Trivia: When being played on basic cable or regular TV, John McClane's catchphrase "Yippee ki yay, mother fucker!" is sometimes oddly redubbed as "Yippee ki yay, Mr. Falcon!" Falcon is the call sign for General Esperanza's original flight, which half explains the odd wording.
Trivia: Cinematic legend and Sam Raimi regular Bruce Campbell plays Darkman in the final shot.
Trivia: Macaulay Culkin, although playing a truly pivotal role, is not credited. Pretty peculiar, huh?
Trivia: Since spiders really aren't a trainable type of animal, the filmmakers used hairdryers to blow on them, in order to get them to move correctly.
Trivia: Ralph wears his arm in a cast for the first part of the film. This is because Balthazar Getty broke both wrists just a couple weeks before filming began, but director Harry Hook liked him so much in the role that he just wrote the injuries into the part.
Trivia: Even though Lionel Jeffries plays Michael Caine's father, he was only 7 years his senior.
Trivia: The entire color palette of the film is limited to seven colors. Every instance of any color is the exact same shade. This was done to evoke the feel of the comic strip origin.
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: Claudia Christian did not want to make the film and only took the job for the paycheck. Reportedly, she frequently got into fights with the director and other cast members, threw a tantrum when she found out she didn't have the biggest trailer, refused to shoot certain scenes, and would often refuse to take direction. She also hadn't disclosed that she was pregnant at the time to the producers, and as a result suffered a miscarriage while filming a strenuous stunt scene. Since she hadn't disclosed the pregnancy, the producers were not held liable for the incident. They reluctantly allowed her to return to the film with the condition that they wouldn't sue her for the monetary losses she had cost the production, amounting to around $200,000.
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: Richard Gere and Andy Garcia did not get along during the filming, and much of their fighting in the elevator sequence is real.
