Trivia: Producers Gale Anne Hurd and Sam Mercer wanted to film the movie at the American Museum of Natural History in New York. However, the museum's administration was afraid that the film would not only cast the museum in an unflattering light, but it would also scare kids away from the museum. They were given permission by the Field Museum of Natural History in Chicago to film there, because they loved the movie's premise.
Trivia: When composer Éric Serra showed Inva Mula, the Albanian soprano who was going to sing the Diva Dance, the sheet music for that part, apparently she laughed and said that it was impossible for the human voice to switch from high to low notes that quickly. She got her way: The part that ended up in the film is not a single piece of audio, rather it's several pieces stitched meticulously together.
Trivia: At the start of the first scene, when Nisi serves the customer she calls Nate, he is played by Rudy Ray Moore, known for the title role in the film "Dolemite," one of the most popular Blaxploitation films of the 70s. After Nate refuses the burned toast, Mickey tells Nisi, "Girl, don't pay him no mind, he thinks he's Dolemite." Also, note the name "N. Townsend" on Nate's uniform patch, which is the last name of the director, Robert Townsend.
Trivia: John Woo fought to keep the slash in the title, so moviegoers wouldn't think it was a film about hockey.
Trivia: A little aside - when the terrorists first strike, in amongst the confusion you can hear someone shout "get the football!" The "football" is the name used for the case which contains the nuclear launch codes, but this is never explained. It's not a major thing, but interesting to note that they included it as a little detail. Good to know a childhood spent reading Tom Clancy books wasn't wasted...
Trivia: Burt Reynolds turned down the role of Jack Horner several times, he finally agreed to do it reluctantly. He hated the film, and thought his acting was terrible and that the film would be a total bomb, so he publicly denounced it. He even fired his agent. However, when it came out it was hailed as Reynolds' comeback role, and he was nominated for an Academy Award. He then changed his opinion of the film drastically.
Trivia: At the end of the movie, the plane is crashing into the front of a casino. This building is actually The Sands hotel. The scene was done a few weeks/months before the hotel was demolished, this way the damages to the hotels entrance as the plane was launched into it didn't matter.
Trivia: The part played by Meatloaf was first given to boxer Frank Bruno who quit the film during filming as his son wasn't allowed on set to get the spice girls' autographs.
Trivia: Hammond doesn't appear in the second book (though he does in the second movie). This is because, in the book series, Hammond was killed in the first book. He slipped, broke his ankle and was fatally attacked by compies.
