Trivia: The man that shows up at the door to ask about the orgy, is the director of the movie: Todd Phillips.
Trivia: The boy who played Owen received a dog just like Nelly at the end of shooting the film. The crew pretended it was an extra scene so he would be surprised.
Trivia: In the opening scene, when the girls are flipping through a photo album they've made for Elle, they get to a picture of her with Sally Field, and one of them remarks, "I like them, I really like them." When Sally Field won her Oscar, she said, "You like me, you really like me."
Trivia: When the film was released during the war with Iraq, the poster of the film was edited by airbrushing the peace sign that Amanda Bynes made. This was done by Warner Bros. so no one will think that the poster is a war protest, or make it seem that the studio is against the war.
Trivia: When Harrison Ford is walking through the old guy's mansion, there is a shot of them walking down a hallway. This is the same shot (and house for that matter) that was used in the movie Fletch when he was talking about how Hopalong Cassidy used to live in that house. The front of the house with the fountain in the middle of the circle driveway is also recognizable.
Trivia: Charlie Brown is an actual friend of Sofia Coppola. His real name is Fumihiro Hayashi and he owns a fashion magazine in Tokyo.
Trivia: In the casino, while D.J. is fighting with Yosemite Sam's goons, Daffy tells him to "bite his ear." This is a reference to boxer Mike Tyson, who bit off a portion of Evander Holyfield's ear during a match.
Trivia: When Roy is talking about his ideal life with Lynn, he mentions his three children, "Vera, Chuck and Dave," a very slick reference to the Beatles song "When I'm 64."
Trivia: Just after Steve Martin finds out that Queen Latifah is a convict you see a picture of her where she is holding up her jail sign. Her name is Charlene Morton. Morton is the last name of Queen Latifah's character in Chicago.
Trivia: There is one error in the Tag Team race: the street is not that long. (I should know, because my dad works on that street.) In the movie, it took a little while to finish getting down that street which was unbelievable, especially at the speed they were going. In reality, if you were to race down that street from where they started (without turning back) it would take you an estimated eight to nine seconds.
Trivia: When Cindy and the rapper guy are fighting the Ring girl, the president walks in and says, "I just want to wish you both good luck. We're all counting on you." and then he walks out. This is a joke from "Airplane" where Leslie Nielsen is the doctor. He says the same line. The reason it is in the movie Scary Movie 3 is because the director of Airplane also directed this.
Trivia: In the film poster, the "Not alone" on Halle Berry's forearm is written running from wrist to elbow. However, in the film, when she removes her bandages, it runs elbow to wrist.
Trivia: During the film's opening number, pay attention to the shot when Kenai is riding the back of the mammoth, busting through the fishing net that his brothers are holding. If you look very closely, you'll see Nemo, from Finding Nemo, right there along the flying salmon. He's only in three short frames, so it helps if you pause the DVD and go frame by frame. (00:04:45)
Trivia: Near the end, the publisher tells Sarah Morton that he is disappointed in her latest book and asks her "Where's the plot twist?" Interestingly enough, the viewer is presented with a very big plot twist a short while later as the movie ends.
Trivia: Lara tells Terry that she will take "four minutes" with Chen Lo. The fight sequence between her and Chen Lo ends almost exactly four minutes later.
Trivia: This movie was so low budget that they actually used clips from other films for some scenes. When Steven Baldwin first meets Nicolette Sheridan, she's arguing with two tourists about the "rickety old" airplane they've booked a flight on. We never see the plane until it takes off, because all of the footage of the airplane is from the movie "Six Days, Seven Nights." When they're in the cockpit (a close-up, obviously a different plane), Nicolette is in the pilot's seat and Steven is on her right. When the plane is coming in for a landing, Harrison Ford is flying the plane and Anne Heche is in the co-pilot's seat. After the plane crashes, the four characters are sitting on the beach and the plane is nowhere to be seen.
Trivia: The voices for the singing busts are provided by the Dapper Dans, a barbershop quartet that performs regularly at Disneyland park in Anaheim, California.
