Trivia: Due to the political situation in Iraq, the location for scale shots was moved from Morocco to Mexico, an ideal alternate choice with its broad beach. However, the rushed decision presented some obstacles. Coastal Mexico is an endangered turtle habitat, so to be granted permission to set up the Greek encampment and build boats on the large stretch of beach, the film crew implemented their own turtle incubation nursery, releasing a multitude of turtles while on location in Mexico. They also did not have an accurate idea of the physical conditions of that particular beach - it was unstable and 100 feet of beach washed away overnight, leaving Greek ships teetering precariously on the edge of the bank with the missing sand.
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: During filming, George Clooney paid a visit to his friends on the set of "ER" wearing the batsuit.
Trivia: John's request for "guns...lots of guns" mirrors a line Keanu Reeves has in The Matrix.
Trivia: Just before Hannibal, Face and BA break Murdoch out of the hospital by driving the hummer through the wall, watch the credits rolling on the screen of the movie they are watching. Reginald Barclay is the character that Dwight Schultz (the original Murdoch) played on Star Trek: The Next Generation, and the 2nd name ends with "StarBuck", the character played by Dirk Benedict (the original Face man) on Battlestar Galactica. We also see "Thomas", with the surname obscured - likely "Thomas Banachek", a character played by George Peppard, the original Hannibal.
Trivia: Kevin Peter Hall, who plays the Predator, also appears as the pilot of the general's helicopter at the end of the film.
Trivia: After the fight in the nightclub, when Indy and Willie make their escape, the name of the club is visible as they drive away - Club Obi Wan - a reference to Star Wars, also by George Lucas.
Trivia: Bill Millin, Lord Lovat's piper, earned the nickname 'Mad Piper' due to the fact that he was spared by German snipers on D-Day because they thought him to be crazy playing bagpipes in the middle of a war.
Trivia: Stars Paul Newman and Steve McQueen apparently argued intensely over who should get top billing. In the end the producers settled for a compromise: reading the film poster (which is reproduced as the DVD cover) top to bottom, Paul Newman is first, i.e. higher, or "top" billing. But reading left to right, Steve McQueen is first. The same applies to their photographs either side of the main artwork, McQueen on the left but Newman (marginally) higher up. Ironically, this billing format was an issue when McQueen was considered for a role in "Butch Cassidy and the Sundance Kid."
Trivia: In Greek mythology Persephone was the wife of Hades, ruler of Hell. Persephone is the wife of the Merovingian, ruler of the Hell Club.
Trivia: Director Oliver Stone claimed that the lead character of Chris was largely autobiographical and mirrored many of Stone's own experiences as a soldier in Vietnam.
Trivia: The teddy bear that Bruce Willis brings to his son is the same bear Alec Baldwin brings home to his daughter at the end of "The Hunt for Red October," which is another John McTiernan film.
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: The first scene in which Obi-Wan and Anakin appear was filmed after principal photography had finished. Ewan McGregor had shaven off his beard, so he had to wear a fake one.
Trivia: In the scene with George swinging from the Bay Bridge in San Francisco, that's actually Brendan Fraser, not a stuntman. He enjoyed the rush so much that he requested an extra take just to swing again.
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: 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.
