Trivia: During the controversial bathtub scene, Cameron Bright was never naked and he and Nicole Kidman were never even in the same room during the filming of the bath scene, apart from one camera shot, and when this shot happened both actors wore special clothes that were not visible to the camera.
Trivia: The eye that we see at the beginning of the movie (when the dragging cars engage NOS) belongs to Adam Scott, who played Special FBI Agent McPherson.

Trivia: Near the start of the movie, when Greg & Pam are on the plane, the stewardess who asks Greg if he wants help with his case, is the same one that he shouted at near the end of the first movie.
Trivia: The movie the kidnappers are watching is "Final Destination 2" (2003), which was directed by David R. Ellis. Also there is an announcement at the aiport for "Volé Flight 180 to Paris," a reference to the original "Final Destination" (2000). Both are New Line productions.
Trivia: In the opening of the movie, David Duchovny is seen riding his bike through Paris. Apparently, in the shot where he is riding through the middle of traffic was not planned or rehearsed, he simply began riding a bicycle through heavy traffic while the camera man filmed him. He attributes this foolish choice to his "Having drank a glass of wine" earlier that night.
Trivia: Much of the scene with Largeman and the doctor in his office was ad libbed by Ron Leibman. Liebman made up patting Braff on the knee and saying "Hey, you're alive" on the spot, and Braff actually did jump from it. He also did some research by calling other doctors, and threw in the line about taking off his shoes and scratching his feet at the very last moment, something doctors actually do.
Trivia: The directors had Sam wear a lot of blue throughout the movie to standout and show she stood apart from everyone else. They tried to get all the other actors and extras to wear as little blue as possible. If you pay attention, Sam is often wearing blue and all the teenagers in the background wear jeans a lot less than you would probably see at a high school.
Trivia: When Frosty has just been smashed up and we see his head, the light in his eye goes out a bit like the terminators at the end of "Terminator 3" (2003).

Trivia: The mysterious new leader of the flying daggers never actually appears because that role was intended for actress/ singer Anita Mui, who resigned the (impending) filming due to ill health two weeks before dying of cancer. Out of respect Zhang Yimou didn't replace her with another actress and the film is dedicated to her memory.
Trivia: In the final scene were XXXX is in the Park club dining with Trever, Morty, Gene, and Clarkey there is a shot outside the room looking in where XXXX is standing and the others are raising their glasses to him. This is similar to the final scene in 'The Godfather'. This is said during the director's commentary.
Trivia: The film was almost entirely shot in high definition. Director Michael Mann states he did this to capture the night scenes more vividly.
Suggested correction: The number of movies shot in less-than-HD could be counted on one hand.
I believe it refers to the fact that Collateral is considered to be the first major movie to use a digital camera, not the traditional film support.
Trivia: Unlike popular belief, this was never meant to be the "last Godzilla movie ever." This was merely meant to be an anniversary and a last Godzilla movie for at least 10 years, maybe even more. The director of the movie even expressed interest in how the future generations would treat the King of the Monsters in future movies.
Trivia: Megan Park, who plays Becca, also stars as Grace Bowman in "The Secret Life of the American Teenager." In this movie, her mom's name is Kathleen. In the series, her mom is also named Kathleen. She also plays the roll of a religious girl in both.
