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: 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: At the end of the film, Rush is killed by Blade, who is hiding behind the curtain at a peep-show booth. In the 1996 film "The Crow: City of Angels", the lead character Ashe surprises a villain in the same manner. Both films were written by David S. Goyer. Goyer had disowned "The Crow: City of Angels" however, due to studio-enforced edits, and decided to re-use the scene in this film.
Trivia: The trivia and in jokes abound in this film. Firstly, you have Janet Leigh (Jamie Lee Curtis' mother) playing Norma (reference to Psycho) and complaining that the "showers are blocked again" (second reference to Psycho). In her last scene in the film, Janet Leigh is about to get into and drive away in the same car that she used in Psycho.
Trivia: Paul Thomas Anderson, who directed Tom Cruise in Magnolia, has a cameo on the train. It is reported that he is so hard to find that Anderson himself does not know where he appears.
Trivia: Betty Buckley really slapped Nancy Allen across the face during the detention scene. Brian DePalma wanted the right reaction.
Trivia: An explanation for why there is no salt acid booby-trap protecting the gold book like there was protecting the black book. In the missing scene some of Imhotep's priests burst through the floor/ground and attack Jonathan and Rick, who get tossed aside. The priests then open the gold book's hiding place and get burned all up by the salt acid. You can even see when Rick grabs the TNT that there is smoke rising from the hole.
Trivia: There are 133 F-words in this movie.
Trivia: Following the Disney tradition of hidden Mickey Mouse images, in this film Prince Caspian's vest has many hidden Mickeys, shaped with staples, close to the neck.
Trivia: When filming ROTJ, Lucas didn't want anyone to find out that they were shooting the third Star Wars movie, because pandemonium could break out. So when someone asked the crew what they were filming, they said "Blue Harvest". All of the crew had shirts and hats that said Blue Harvest on them. The fictitious film's tagline was "Horror beyond imagination."
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: 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: According to the DVD commentary, the entire budget for Underworld was the same as the highway chase scene in The Matrix Reloaded.
Trivia: When John and Jane are questioning their former apparent target near the end of the film, look carefully at the guy's shirt - it's the logo from another Brad Pitt film, Fight Club.
Trivia: Gene Barry and Ann Robinson, stars of the 1953 version of this movie, make a small cameo in this movie as Mary Ann's parents. You can see them at the end when the whole family is reunited.
Trivia: Since Drew, Cameron and Lucy are all anti gun, they went through the entire movie using alternatives to guns.
Trivia: Sigourney Weaver actually makes the basketball shot. Even though the ball is out of shot for a second, she made the shot with no assistance. The shot cuts quickly because Ron Perlman dropped character in celebration, which can be seen in deleted scenes online.
Trivia: When they are preparing and listening to the tape you can see a bit of smoke in the air. There had been an extended scene where they had been smoking pot and joking around. However, they used real pot when filming and much of what was shot ended up being unusable as a result. This is according to Bruce Campbell's Commentary to the DVD.
