Trivia: The big fight scene is spoofed in "South Park" when the crippled kids Timmy and Jimmy fight, instead of the film's Nada and Frank. The episode is called "Cripple Fight".
Trivia: During filming, Alan Rickman was found proficient at mimicking American accents; the scene in which McClane and Hans Gruber meet was then inserted.
Trivia: When Chucky is running behind Maggie, many children and child relatives of cast and crew were filmed doing the run while dressed up as Chucky, including Alex Vincent's younger sister, since it would have been impossible for the animatronic Chucky to run across screen like that. However, it is unknown which child ultimately was used in the final cut.
Trivia: Pat Roach - General Kael - intended to do the stunts by himself, but there was one thing that prevented this: "Insurance - they wouldn't let me." So horsemaster Greg Powell did the stunts for him.
Trivia: When Corey Feldman is banging the dent out of the hood of the Cadillac, he says not to worry about waking his parents as they are vampires. Feldman's movie before this one was Lost Boys where he was a vampire killer.
Trivia: The horn sound that is continually made by Leviathan is Morse code for "God".
Trivia: When the Regulators are making their escape out of the house at the end, if you look at the extra shot right after Charlie (Casey Sizemaszko) busts out of the house, you'll see a young Tom Cruise. He was on-set visiting with friend Emilio Estevez and got into makeup (including huge sideburns) and on-screen.
Trivia: Peshwar, Pakistan, actually was the site of many refugee camps and Afghan rebel support, and American intelligence operated out of nearby Islamabad, and the muhajadeen operated principally in the supposed "50 miles over the border." Especially considering the movie was filmed in Israel, the geographical shots are also pretty accurate, with only one problem: when Rambo says "across the valley is the border," across a plain with mountains in the distance, they are supposed to be escaping into Pakistan. There is only one spot where they could be, and it's right in the middle of the Khyber Pass, inaccessible to Russian tanks and armoured vehicles. The Russians would be riding on donkeys, not tanks. The only such place near the Afghan border that such a battle could take place would have Rambo and Trautman escaping into Iran.
Trivia: All of Dennis Farina's scenes were shot in Las Vegas; he was there filming his TV series Crime Story at the same time.
Trivia: The hot tub used in the love scene was constructed of untreated wood and the water wasn't chlorinated. Michelle Pfeiffer, her double, and Mel Gibson suffered splinters and rashes during filming. Michelle lost time off the set as she recovered from her rash.
Trivia: When Schwarzenegger and Belushi are in the diner after shooting the transvestite, Belushi is going through the paperwork that needs to be done. The one sheet which is shown Belushi says is an "accident report". Actually typed at the top of the paper is "Worthless Document Case Report". (01:09:40)
Trivia: At the time Jean-Claude Van Damne was merely a well known kickboxer in Europe but was anxious to break into Hollywood. When spotting producer producer Menahem Golan coming out of a restaurant one evening, he spied his chance. He began with the standard, tried and tested basic method of introducing himself, but then departed from the norm somewhat and added his own flourish by doing a 360 degree spinning kick that only just missed Golan's head. Non conventional, yes, but effective, as Golan swiftly signed him up.
Trivia: At the end of the movie, the Carol-Anne that Pat is holding is really a double, because Heather O'Rourke died from intestinal stenosis, shortly before the movie was finished.
Trivia: When the film was released, Axl Rose told the crowd at Hilton Coliseum, Ames, IA, on 27th July 1988, not to waste their money and see "The Dead Pool," despite being in the film. Confirmable by listening to the show.
Trivia: The taxi driver who hands over the matches to Harrison Ford is the film's director, Roman Polanski.
