Trivia: Lawrence Kasdan was originally set to direct, but dropped out.
Trivia: In the dream sequence of the asylum where Amanda Krueger is trapped by the hundred maniacs one of the maniacs looks remarkably like Freddy. Presumably this was his biological father. (Of course this man was played by Robert Englund, the actor who plays Freddy)

Trivia: Much like the set of War of the Worlds, the set of this crash was so realistic, that airline pilots near Toronto were calling in a downed aircraft as they flew near it, unaware that it was staged for the filming of this movie.
Trivia: The first time we see Riggs in his trailer, there's an advert for some new aftershave called "Hero" on the TV. During the attack on his trailer later, there's a close-up shot of a bottle of aftershave being destroyed - freeze-frame it and you'll see the brand: "Hero" again.

Trivia: In this film, to get back at Kathleen Turner, Michael Douglas saws off all the heels of his wife's shoes; in the film "Romancing the Stone", which was filmed earlier, Michael Douglas, using a machete, chops the heels off Kathleen Turner's shoes for practical purposes.
Trivia: On the promotional movie poster, a frazzled Steve Martin is shown holding 2 children upside down by their ankles. On the set, sometimes the children would get unruly, so as a joke, Steve Martin once grabbed 2 of the unruly children and actually held them upside down by their ankles. Director Ron Howard saw this and decided it would make a funny promotional picture, so that's where he got the idea for it.
Trivia: When Jerry returns home after his fight with Myra over her virginity, the theme song of "Gone with the Wind" starts playing. Jerry then scoops Myra up in his arms and carries her off to bed, just as Rhett Butler did to Scarlett.
Trivia: Although in real life Principal Joe Clark improved the discipline problems at Eastside High School, he did not, contrary to what the film has you believe, improve the academics in any meaningful way. Although test scores improved very slightly his first couple of years as principal (partly due to the fact that he expelled so many bad students) from 1986 to 1988, during his time as principal, Eastside High School had the lowest state exam passage rates in all of New Jersey. One of these years in particular, under Clark's tenure, Eastside High's passage rate was as low as 24.1%.
Trivia: Take a look at the tall Redfeather girl who pals around with the shorter blonde one- it's a young Tori Spelling.
Trivia: Peter Jackson ran out of budget money during production, so the Vietnam flashback was filmed, under a separate budget, as 'The Frogs of War', and then incorporated into the film.
Trivia: In one version of the script, Martin finds another videotape of his father Seth. This tape would show Seth (who is in his part-fly form) explaining the "cure". This scene would have required Jeff Goldblum to be in make-up for five hours, and he didn't want to go through that, so he dropped out, and the scene was cut from the script.
Trivia: During the fight scene between Jimmy and Dalton, Jimmy slams a log against Dalton's chest. The log you see here is a real one. Marshall Teague thought the log was a breakable prop and kept slamming it into Patrick Swayze's chest with each take. By the end, Swayze's chest was covered in bruises.
