Trivia: When the alien's hand comes out of the coal grate for Morgan, if you look closely you will see that the hand was already through the grate and the alien was using its colour changing abilities to hide. So if you look very closely you will that that the hand comes UP from the grate and not through it, and if you look VERY carefully you can see the outline of the hand even before Morgen says "What?"
Trivia: The message "For Sasha" which appears just before the end credits is a dedication to director Nick Cassavetes' daughter.
Trivia: In the party scene at XXX's house after he pulls the stunt with the Corvette, Joshua Todd, the ex-lead singer of Buckcherry, makes a cameo appearance - he never turns around, but you can see the suicide king of hearts tattoo on his back.
Trivia: Closely listen to the TV playing in the background, when Mathew Broderick comes home from school, before all his trouble starts with the Feds. The local news is on, and is saying "a fire broke out in a prophylactic recycling factory."
Trivia: Nicolas Cage has no speaking lines throughout the entire movie.
Trivia: In the scene where Ripcord and Duke are in the transport and Ripcord pats Heavy Duty on the back and gets his arm twisted as a result, Ripcord makes a crack about Heavy Duty having a "Kung Fu Grip". This refers to some of the earliest G.I. Joe's action figures who were advertised to have the Kung Fu Grip.
Trivia: The "Bride in Black" is played by a man wearing women's clothing. This was done so that something would feel "off" about the image of the ghost. At the time, the character was intended to be female. However, when the creators later reused the character for the sequel and added in a backstory, they worked the fact that the character was played by a male as part of his backstory - it actually is a man who masqueraded as a woman as a disguise to lure in victims.
Trivia: The studio and producer Joel Silver reportedly called for major re-writes of the script shortly before shooting began. Many of the actors had signed up based on the original script, titled "Chimera", which contained far less violence and supernatural elements, and instead was a psychological drama about what happens to a salvage crew when they are stranded in the middle of the ocean. Much of the cast wasn't informed that the script had been almost completely altered into a more generic supernatural-horror/slasher film until just before they showed up to begin filming, leaving many of them disheartened and disgruntled.
Trivia: Holly Hunter's role is one of the shortest Oscar nominated performances. She only appears on screen for about six minutes total.
Trivia: When Agent Strahm is in his head box trap screaming, there is a lot of flash-cutting, including a shot of an outtake of the actor smiling with a towel in the cube and staff around him. Happens exactly at 9:52:370 into the movie, or frame 14203. VERY fast and easy to miss.
Trivia: Alfred Hitchcock chose Raymond Burr to portray the villainous Lars Thorwald due to his resemblance of David O. Selznick, a producer Hitchcock hated.
Trivia: Part of the reason Alice (the survivor of the first film) is only on screen during the first scene and is killed off early is because the actress portraying her (Adrienne King) was dealing with a real-life stalker and was trying to limit her acting appearances.
Trivia: Director Christophe Gans wanted to use the original soundtrack recordings of Akira Yamaoka's scores from the various "Silent Hill" video games in the film. However, due to a legality issue necessitating the hiring of a Canadian composer for the film, Jeff Danna was selected to serve as the lead credited composer. However, it was later confirmed that he actually composed very little original music for the film, and instead mainly focused on created re-mixes and new recordings of the themes from the video-games, so that he and director Gans could preserve Akira Yamaoka's music and style as much as possible.
Trivia: Robert Duvall was asked to reprise his role as Tom Hagen, but an agreement couldn't be made on the price.
Trivia: This is Pierce Brosnan's least favourite Bond movie of the four in which he appeared. Brosnan disliked the over-the-top special effects and gadgets, and suggested to the producers that the follow-up should be dark and gritty. After Brosnan left, the series was indeed given a grittier reboot.
Trivia: Robert Englund has stated that out of all of the kills in the entire Nightmare franchise, Carlos' death is his personal favorite.
Trivia: The film had a notoriously troubled production, with several writers and directors dropping out of the project during development. With a looming release date, sets were built and a crew was assembled before a script was even settled on, and the final draft had to be written around the sets that had already been built. David Fincher, then a popular music video and commercial director, was chosen to helm the film, but he had nonstop creative difficulties with the producers and studios. He has since gone on to disown the film, as he feels it isn't reflective of his vision.
Trivia: The pre-credits sequence is 14 minutes long, making it the longest in the history of the series. The original intro was simply Bond's escape from the meeting, rappelling down to the ground, but audiences were underwhelmed by that leading straight into the credits. As such the boat chase was included too, leading to the long intro. It was eventually surpassed by No Time to Die in 2021.
Trivia: M3gan's scenes were done with an actual person wearing a mask (with some CGI being used to animate the eyes and face.) The girl's name is Amie Donald, and she is an accomplished gymnast and dancer, and in the scenes with the hallway dance and running on all fours were not special effects, Amie actually did those moves.
