Trivia: The incredibly short shot of Tortuga when it is first shown (with the man being dunked and such) was actually filmed on the Pirates of the Caribbean ride in Disneyland. While the ride was shut down for remodeling, the crew actually went there and shot the scene with a mixture of live actors and existing animatronic props. If you look closely, many of the "actors" can be seen as fake.
Trivia: The rings worn by Jack Sparrow are not mere props, but rings that Johnny Depp actually owns. After completing the first film and learning of the second and third installments, Depp actually bought several rings specifically for the Pirates films. Another one of the rings he wears is actually a replica of an antique ring he owns.
Trivia: In the first visit to Tia Dalma's House, there are references to Barbossa showing up for the ending. While Will is talking, you can see Jack Sparrow pick up and look at Barbossa's hat. When the monkey jumps from its cage, you can see him run into the other room and jump on a pair of boots in bed, which belong to Barbossa as well we later see.
Trivia: Davy Jones's tentacles were inspired by a stained coffee cup. The special effects team was puzzled when they tried to figure out what the color and texture of his tentacles should be. Then they saw a used cup on the table with a coffee stain on the inside, so they scanned the stain into the computer and that's how he got his tentacles.
Trivia: The game that Will Turner plays with Davy Jones with the dice is a genuine game called Liar's Dice, a gambling game where each player has to make consecutively higher bids based upon how many of each die they claim are on the table (two threes, four fives, etc), until a player is called a liar, in which case all the dice are shown and it's seen if the bid is correct.

Trivia: Ted Elliott and Terry Rossio explain in their commentary that the scene where Will is talking to Cotton's parrot was originally much longer, with Will insulting the parrot and later apologising. We see none of this in either of the two DVDs - there are no deleted scenes. However, in the easter egg 'The Coconut Man,' we see this scene being filmed.
Trivia: According to the film's writers, Terry Rossio and Ted Elliott, in the DVD commentary, the ship captain that Mercer kills is named Hawkins. He is the father of Jim Hawkins from Robert Louis Stevenson's "Treasure Island." In that novel, Jim's father, a ship captain, disappeared without a trace. Rossio and Elliott decided to provide their own explanation as to what happened to him.
Trivia: The footage shown immediately at the beginning of the Tortuga sequence, including men dunking the mayor in a well etc. was originally filmed for the first movie, The Curse of the Black Pearl. However, it was cut out in the editing process, and was subsequently reused for Dead Man's Chest. You can see this edited sequence in greater length on the Special Features DVD of Pirates of the Caribbean: The Curse of the Black Pearl.
