Trivia: Johnny Depp passes an old bald man with hippy glasses sitting down surrounded by women - this is author Hunter S. Thompson himself in a cameo.
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: 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. A few seconds later we see George Bush Sr. talking about Iraq. So here we have a scene containing Sept. 11th, George Bush and references to the Middle East in a movie that takes place in 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: 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: In the courtroom scene, all the people that have turned to color have to sit on the upper level.

Trivia: When the original novel was published, the author was identified as "Anonymous." 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. Investigators had shown that the writing style found in "Primary Colors" is identical to the writing style found in Klein's Newsweek articles.

Trivia: The mug shot of George Clooney is the same one that was used in "From Dusk 'Til Dawn."
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. Also, in the locker room, where he (sarcastically) says how Doug Reemer "really cares about kids", the voice he puts on is that of Mr. Garisson, the teacher at South Park Elementary (also voiced by Parker).
Trivia: Adam Sandler was paid by the old lady with a meatball, which is the name of his dog.
