Trivia: When Jigsaw and Eric escape the lair via a hidden elevator, the film's low budget prevented the construction of an actual working elevator. Thus, some trick photography and editing was implemented. For the first shot of Jigsaw and Eric "going down", the scene was shot by raising the camera vertically to give the impression they were descending. For the next wide shot, simple digital effects were added to make it appear that the room was "lowering." And for the final shot where we see the top of the elevator going down an elevator shaft, stock footage from the film "Hollow Man" was used.
Trivia: Some people wanted the Batmobile to be computer generated, but director Christopher Nolan refused, so it was built from scratch. It can do 0-60 in 6 seconds.
Trivia: Director John Singleton can be seen briefly as the goalie in the Thanksgiving hockey game. (00:19:35)
Trivia: Rob Zombie is a huge horror and slasher movie buff and he makes this well known in Devil's Rejects for there are many scenes that are tributes to slasher films. The Sheriff chasing Baby Doll through the cattle farm is from 2003's remake of Texas Chainsaw Massacre as is Otis wearing the husband's face as a mask. Otis attacking the girl in the shower is a nod towards Psycho. The sheriff using an axe is from the Shining (watch how he kills Charlie. It is the exact same way Jack Nicholson kills the cook in Shining). The tale of the traveling killers is a hint towards Natural Born Killers and the idea of a the cop extracting revenge on those who killed his family member is from The Last House on the Left where a girl's parents take revenge on a group of rapists and killers.
Trivia: Viola Davis plays 50 Cent's grandmother in the movie, even though in real life she's only 10 years older than him.
Trivia: "The Interpreter" was almost banned from Zimbabwe because of the similarities between the Matoban regime of Dr. Zuwanie and that of Zimbabwean dictator Robert Mugabe.
Trivia: The scene where the drunkard sees the car go above him and thinks it's just his imagination is a homage to the Bond movies "The Spy Who Loved Me", in which a character has the same reaction when the car drives out of the water, and "For Your Eyes Only", in which that same character has the same reaction when Bond skis overhead.
Trivia: In the American version of this film Jessica Alba's bikini bottoms were digitally extended to cover her buttocks. In the European version they remain the same.
Trivia: Watch the deleted scene when they rob the toy store, the music is unmistakably from Lemony Snicket's Series of Unfortunate Events movie (which also starred Jim Carrey).
Trivia: The ice that Vic dies in is only wax over water made to look like ice.
Trivia: It was said that Dick Clark was hosting New Year's Eve. You also heard Dick counting down to a 2005 lighting of the ball. In actuality Dick Clark did not host the New Year's Eve Countdown in 2005 year due to being in the hospital from a stroke. Regis Philbin did. Unfair to count this as a mistake as the film was shot in 2004 (released early 2005), so they weren't to know, but worth noting.
Trivia: Rob Cohen (director of the first film) and Vin Diesel (star of the first film) had both signed on to work on this sequel. Cohen had even begun early work on the project, after having very much enjoyed working on the first film. However, due to time constraints and scheduling conflicts with other projects, both had to drop out of their respective roles, and Diesel Xander was unceremoniously "killed off." Both Diesel and Cohen were unsatisfied with this film, with Diesel in particular expressing an interest to return. Diesel later brought the series back with 2017's "xXx: Return of Xander Cage."
Trivia: When Director Andrew Niccol was out buying thousands of AK-47 for the movie, he found that the real stuff was less expensive and more readily available than fakes. After the movie he had to resell them, and found himself becoming an arms dealer.
