Trivia: In the evidence depository in the beginning you can see Jason Voorhees' hockey mask (Friday the 13th), Leatherface's chainsaw (Texas Chainsaw Massacre), Michael Myers' mask (Halloween), and Freddy Krueger's glove (Nightmare on Elm Street). (00:00:45)
Trivia: As Hal meets Meredith coming out of an elevator in the hotel, she is mumbling "Let's Get Together", which was a song from the original movie.

Trivia: At the beginning of the movie, when The Dude is writing a check for the cream at the grocery, look at the date on the check. Sept 11, 1991.

Trivia: When Ryan (Leslie Nielsen) jumps away from the bus as it gets hit by a train, Ryan lands on a bicycle that doesn't have a seat. In the movie The Naked Gun 2 1/2: The Smell Of Fear, Frank Drebin (also played by Leslie Nielsen) tells Hapsburg that the truth hurts, but not as much as jumping on a bicycle with no seat.
Trivia: In the courtroom scene, all the people that have turned to color have to sit on the upper level. This is reminiscent of "To Kill a Mockingbird" (1963) where, in a similarly-built southern courthouse in the 1930's, all the "colored people" (African Americans) were relegated to the upper level.

As a result of curious professors and investigative journalists trying to identify the author, the person was identified as Joe Klein, an American magazine columnist who was working for the newsmagazine Newsweek.

Trivia: After Rodmilla and her daughters leave for the masque, during the next scene at the royal palace a large sculpture can be seen in the courtyard, especially in some closeups from different angles, such as when Gustave approaches Leonardo. This mythologically themed sculpture consists of a tailed figure riding upon one of two creatures holding their reins, with a ship behind them. This sculpture can be seen during the very first scene, albeit with a few changes. When Wilhelm and Jacob Grimm walk into the Grande Dame's chamber she is sitting up in an unusual type of bed. Note the bed's "headboard" and "footboard" are the ship hull (in the fullscreen version the bed's side is visible with its distinctive design), and we also see the creatures (minus their horns) with the rider's arm holding their reins at the foot of the bed. Something else to notice near the end, when Leonardo gifts the young couple the belated wedding present the room they're all in is not in the royal palace, they are in the manor, gathered in the dining room where Marguerite had burned Danielle's book Utopia.

Trivia: Where Coop is taunting the fat guy in the last match, the voice he puts on bears a striking resemblance to that of Eric Cartman, a character Trey Parker (Coop) voices in the comedy he and Matt Stone (Reemer) created called South Park.

Trivia: Adam Sandler was paid by the old lady with a meatball, which is the name of his dog.
