Trivia: The disclaimer, "Neither the name Zorin nor any other name or character in this film is meant to portray a real company or actual person," was added after the producers discovered a real company known as Zoran Ladicorbic Ltd, whose industry was fashion design. This is the first Bond film to begin with a disclaimer.
Trivia: When Col. John Matrix is with Cooke in the motel, Matrix says the famous phrase: "I eat green berets for breakfast." This was a reference to Sylvester Stallone, who played a Green Beret in the Rambo movies. (00:46:45)
Trivia: In the scene where Meg appears, Richard Picardo had a hard time breathing in the latex costume and mask while underwater. When he/she pops up, look closely; Meg appears to be spitting water and gasping for breath.
Trivia: This is the first movie in human history to ever to feature a fully CG (computer generated) character when the knight emerges from the stained glass window. Computer graphics had existed prior (Wrath of Kahn), but never once to simulate an on-screen character.
Trivia: Tim Burton appears in a cameo when Pee Wee is accosted in the alley on his way to the psychic. He says to Pee Wee, "we don't take kindly to strangers on our turf!" (00:30:35)
Trivia: This was Disney's first PG-rated animated film, and the company caught a lot of flak for it from parents' groups.
Trivia: In the scene at the beginning of the regatta race, on the Barnacle, the shot changes to Laurie asking Sandy: "Mommy can I play in the basement with Yorku"?

Trivia: The only Care Bear and Care Bear Cousin that do not make an appearance in this movie are True Heart Bear and Noble Heart Horse.
Trivia: This is, the way I see it, a VERY serious mistake by the filming crew of the movie. The Alaska Railroad, where the shooting of the movie took place, wanted all their logos and paint schemes of all the trains in the movie to be camouflaged. But yet, on the first shot of the locomotive of Eastbound 12 (yes, that is the shot of it before it mysteriously changes from ONE GP40 to TWO ALCo MRS's), you can see the blue and yellow paint scheme of the Alaska Railroad. On the DVD you might even be able to see the printed ALASKA on the side of the loco.
Trivia: Here are some interesting tidbits about where some of the aspects of the movie came from, which is a compilation of the books following the first. Jack Pumpkinhead, the Powder of Life, the Gump, Mombi, Ozma (Tip) and the escape off the top of the roof all come from 'The Marvelous Land of Oz'. The multiple heads angle, the Gnome King's Nick-Nack game, the chicken coop, Billina, and Tik-Tok all come from 'Ozma of Oz'. The tunnel under the Deadly Desert that Mombi uses to get to the Gnome King seems to come from 'The Emerald City Of Oz'.
Trivia: Director Jeannot Szwarc has a cameo in this movie as a cameraman during B.Z.'s hearing.
Trivia: Gary Busey ad-libbed a majority of his lines. When director Daniel Attias told Stephen King about this, Stephen said he was OK with it.
Trivia: In the days before ubiquitous digital technology, the majority of visual effects in film were "practical" effects using stuntmen and props on wires, springboards, flash-pots, et cetera. In "Ladyhawke" (which was decidedly on the low-end of visual effects budgets), one of the most dangerous practical effects is seen when Matthew Broderick and Rutger Hauer have a heated discussion in the woods and seem about to part company. As Broderick turns to leave, Hauer's 53" longsword sizzles past the boy's left shoulder and embeds in a tree trunk, to Broderick's horror. In fact, the steel sword was real and hurtled to its target on a guide-wire, barely 8 inches from Broderick's back. If you slow-advance the scene, you can see the sword actually changing trajectory in-flight, it was so unstable. The sword came up in a Hollywood memorabilia auction in 2002 but was not sold. http://www.icollector.com/Rutger-Hauer-prop-special-effects-sword-from-Ladyhawke_i169815.
Trivia: Some of the cloud effects were created by dumping colored dyes in tanks of water which were then superimposed into the shot.
