(at around 2h) The scene when Jack Sparrow calls Davy Jones "fish face", and sings to them "I got a jar of dirt", was unscripted and improvised by Johnny Depp, most of the reactions of the rest of the characters are real.
The dice game that Will Turner plays with Davy Jones is 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. Normally, a player only loses a die when caught in a lie, and is not out of the game, until he has lost all of his dice.
Gore Verbinski initially rejected Casting Director Denise Chamian's suggestion to cast Naomie Harris as Tia Dalma, saying that she was too young for the role. Chamian insisted he give her a screen test. Finally, Harris' mother came with her for the audition, also serving as her dialect coach, since Dalma speaks in a partial Jamaican accent.
The Kraken was difficult to animate, as it had no real-life reference, until Animation Director Hal T. Hickel instructed the crew to watch King Kong vs. Godzilla (1962), which had a real octopus crawling over miniatures.
A popular pirate punishment was marooning. The pirate who was being punished was put on an island and left, sometimes for a few days, sometimes permanently. The "dead man's chest" is a small rocky island, so-called, because the rocks reminded pirates of a ribcage. It has no water or shade, and is so low, that waves frequently wash over it. To be marooned on the "chest" was to be given a death sentence under the broiling Caribbean sun.
It is stated in the DVD commentary, that the scene where several people argue how to pronounce "kraken" was added due to an error by Kevin McNally. The word is pronounced "kray-ken", but when McNally first said the creature's name, he pronounced it "crack-en", and this caught on with the rest of the cast. The scene was added to show how the creature's name is actually pronounced.
All of Davy Jones' crew were actors. They all wore dark gray motion-capture suits, and before they could be filmed, they had to be scanned, in order for the computer to place the crew images over the top. Bill Nighy wore make-up around his eyes and mouth, in case computer rendering failed to look realistic during extreme close-ups (fortunately this was never needed).
(at around 1h 7 mins) When Mr. Gibbs is enlisting new recruits at the tavern, a bunch of men are pulling a man out of a well, and he slowly spits out water. This is a re-creation of a scene in the Pirates of the Caribbean ride at the Walt Disney theme parks.
For the film's release, the Walt Disney Company redesigned the Pirates of the Caribbean rides in Walt Disney World and Disneyland to feature Captain Jack Sparrow, Barbossa, and an appearance by the film's supernatural character Davy Jones, as part of the attraction, and premiered on the same day as the film.
This marks famed visual effects house Industrial Light & Magic's first Oscar win since Forrest Gump (1994). This is also the only "Pirates of the Caribbean" film to win the award in any of its nominated categories (as of 2018).
(at around 49 mins) The shack by the river, as the crew goes to see Tia Dalma, is identical to the shack on the far side of the river, across from the boarding dock of the Magic Kingdom's "Jungle Cruise" ride in Orlando, Florida.
Shooting in Dominica proved problematic. The government were completely unprepared for the scale of a Hollywood production, as while the five hundred-strong crew occupying around ninety percent of the roads on the island, they had trouble moving around on the underdeveloped surfaces. The weather also alternated between torrential rainstorms, and hot temperatures, the latter of which was made worse for the cast, who had to wear period clothing.
The hierarchy among the Flying Dutchman crew, is reflected by how mutated they were: newcomers have low level infections, which resemble rosacea, while veterans have full-blown undersea creature attributes.
The MythBusters (2003) attempted to recreate the swinging the hanging cage segment, but were unable to cause the cage to swing far enough to reach the "canyon" wall. They concluded that it was good cinema, but impossible in real-life.
(at around 47 mins) When the sailors fight over the dress on the ship, on which Elizabeth has stowed away, they talk about the ghost of a woman who was widowed before her wedding. This is similar to a plot point in the Disney ride "The Haunted Mansion" at Walt Disney World.
Throughout the movie, many references are made to the original Pirates of the Caribbean: The Curse of the Black Pearl (2003). These include the following: Cutler Beckett is corrected by Elizabeth and Will when he fails to refer to Jack Sparrow as "Captain" (Jack insisted on being called "Captain Jack Sparrow" in the first movie); Governor Swann breaks off an arm of a candlestick inside the dungeon (the same happened to Will in the Governor's house in the first movie); Governor Swann asks where the "dog with the keys" is; the dog is still holding the keys in the rowboat; Jack asks, "Why is the rum always gone?" (he asked Elizabeth the same twice in the first movie); Will gets slapped by a lady in Tortuga (Jack's being slapped by ladies he once mistreated was a running joke in the first film); Jack says "Hide the rum" when Elizabeth arrives (Elizabeth burned his rum in the first movie); a running gag plays on the fact that Jack the monkey is immortal (he stole one of the Cortez coins in the post-credits scene at the end of the first film).
(at around 18 mins) The two sailors quarreling over Jack's hat on the boat, which is then sunk by the Kraken, are from Cyprus. The sailor on the left is Turkish-Cypriot while the other on the right is Greek-Cypriot, and speaks the Greek-Cypriot dialect.
This movie held the box-office record for the highest opening weekend with 135,634,554 dollars earned. The former record holder was Spider-Man 2 (2004). The record was then broken by Spider-Man 3 (2007).
Planning began in June 2004, and production was much larger than Pirates of the Caribbean: The Curse of the Black Pearl (2003). By November, the script was still unfinished, as the writers didn't want Gore Verbinski and Jerry Bruckheimer to compromise what they had written, so Verbinski worked with James Ward Byrkit to storyboard major sequences without need of a script, while Elliott and Rossio wrote a "preparatory" script for the crew to use before they finished the script they were happy with. By January 2005, with rising costs and no script, Disney threatened to cancel the film, but changed their minds. The writers would accompany the crew on-location, feeling that the lateness of their re-writes would improve the spontaneity of the cast's performances.
Gore Verbinski wanted to keep the Flying Dutchman crew realistic, rejecting a character with a turtle shell, and the animators watched various David Attenborough documentaries, to study the movement of sea anemones and mussels.
To portray Jones on set, Bill Nighy wore a motion capture tracksuit, that meant the animators at Industrial Light & Magic did not have to reshoot the scene in the studio without him, or on the motion capture stage.
In an interview with CGSociety, Visual Effects Art Director Aaron McBride revealed that when he was given the task of doing photo-real illustrations of Davy Jones, there was talk that Christopher Walken would play the role.
(at around 1h 8 mins) When Norrington introduces himself to Gibbs on Tortuga, he says that his story is 'the same as yours, just one chapter behind'. Later on he is dumped in the pigsty after the fight in the pub. This is the same setting (perhaps even the same pigs) as where Jack Sparrow found Gibbs in the first movie, the previous chapter.
Chip and Salsa play the parrot that talks for the pirate Cotton (David Bailie). Only one bird appears at a time, but both birds play the same character. Chip performed in most of the scenes where the parrot was required to sit patiently on a character's shoulder. Salsa performed most of the tricks and when a scene required more animation, such as flying.
Orlando Bloom and Bill Nighy have both appeared in adaptations of The Lord of the Rings. Bloom played Legolas in Peter Jackson's films, while Nighy was the voice of Samwise Gamgee in the BBC Radio version.
Bill Nighy later revealed that Scottish sitcom Still Game (2002) influenced his choice of accent, stating: "I had to find an accent no one else had. Although Alex Norton is Scottish, mine was slightly different. We wanted something that was distinctive and authoritative...I have seen Still Game (2002) and I am a fan. The sort of extremity of the accent was inspired in that area."
Filming on Grand Bahama Island was a tumultuous period, starting with the fact that the tank had not actually been finished. Hurricane season caused many pauses in shooting, and Hurricane Wilma damaged many of the accessways and pumps, though no one was hurt, nor were any of the ships destroyed.
In 2006, both Disney World and Disneyland updated the rides and added animatronics of Jack Sparrow, Hector Barbossa who replaced the original captain of the Wicked Wench and Davy Jones to coincide with the release of the film.
Davy Jones had originally been designed with chin growths, before the designers made the move to full-blown tentacles. His skin incorporates the texture of a coffee-stained Styrofoam cup, among other elements.
(at around 1h 35 mins) Captain Jack Sparrow referring to Elizabeth as "Lizzie" could be a reference to Keira Knightley's role as Elizabeth "Lizzie" Bennett in Pride & Prejudice (2005). She was nominated for an Academy Award for this role.
Filmed in the Commonwealth of Dominica in 2005. Producers, cast and crew resided at Portsmouth Beach Hotel and Picard Beach Cottages during filming. It was the largest production the island had hosted as of that year.
The Pelegostos are convinced Jack is a god bound in human form, and want to release him. As it turns out, their idea isn't that far-fetched... When Will is looking for Jack, the last man he speaks to talks about an island where he's seen a marooned ship with black sails, at which he trades for 'long pork'. 'Long pork' being a euphemism for human flesh (although it's left up in the air whether Will would know that.)
(at around 2h 20 mins) For a dose of authenticity in the final twist at the end of the film, the actors were not told, prior to filming, that Geoffrey Rush would be appearing in the movie. They were told, before the scene was shot, that the person coming down the stairs would be Anamaria (Zoe Saldana) from Pirates of the Caribbean: The Curse of the Black Pearl (2003). The looks of surprise on their faces as Rush descends are genuine.
(at around 51 mins) When Jack offers the monkey to Tia Dalma, she opens the cage, setting the monkey free. The monkey then runs off and starts playing with a pair of boots that are attached to a leg (presumably Captain Barbossa's).
(at around 55 mins) When Jack Sparrow is at Tia Dalma's hut, there is a necklace on the table when Jack is stealing the ring. The picture on the necklace is the same image on the music box on Davy Jones' pipe organ, a hint to a major plot point in Pirates of the Caribbean: At World's End (2007).
(at around 21 mins) The black sailor who brings Will to the cannibals' island speaks French when he refuses to go any further and makes Will swim to the shore. What he actually says is: "J'y vais pas, c'est trop dangereux je vous dis." This can be translated into: "There is no way I'm going, I'm telling you it's too dangerous."
According to the novelization for Pirates of the Caribbean: At World's End (2007), Elizabeth felt terribly guilty about leaving Jack to die at the hands of the Kraken at the climax. But she sensed he was proud of her pirate-like behavior.
In the novelization for Pirates of the Caribbean: At World's End (2007), Elizabeth lost some respect for Norrington after he gave the heart of Davy Jones to Lord Cutler Beckett to regain his standing in the Navy, but he never stopped loving her, despite her love of the pirate's life.
When Tia Dalma tells the tale of how Davy Jones fell in love with a woman, Gibbs says that he heard a different version of the tale in which Jones fell in love with the sea. Tia Dalma says that they are two versions of the same story and both are true. Also while Jack is shown shop-lifting from her hut, there's a music box amongst her trinkets, that's matching the one Davy Jones has. Turns out that she's the sea goddess Jones fell in love with.
