There was an actual council of pirates at one time in history. The Brethren of the Coast were a loose coalition of pirates and buccaneers, active in the seventeenth and eighteenth centuries in the Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico. They had a base on the island of Tortuga, off the coast of Haiti, and in the city of Port Royal, Jamaica. The Brethren were originally French Huguenots and British Protestants, but their ranks were joined by other adventurers of various nationalities, including Spaniards and African sailors.
The scene in which Jack the Monkey is shivering, was accomplished by the concerted efforts of the special effects and animal training departments. The effects guys made a small wooden barrel with a vibrating plate on top. The animal trainers taught the monkey to sit with her arms crossed on the plate.
The character of the pirate lord Mistress Ching is likely inspired by the real-life Chinese pirate Cheng I Sao (or Ching Yih Saou), who controlled the South China Sea with her large pirate fleet in the early 1800s.
Johnny Depp thoroughly enjoyed working with his co-star Geoffrey Rush in the first film, and was pleased to get more screentime alongside him: "We were like a couple of old ladies with knitting needles!"
The film is the first in the franchise in which Captain Barbossa's first name, Hector, is said. Interestingly, the writers did not initially plan on giving the character a first name. In the commentary for Pirates of the Caribbean: The Curse of the Black Pearl (2003), Johnny Depp jokingly said that Barbossa's name was Hector. This comment was misinterpreted by fans to be the character's actual name, and thus left the writers to feel that they had no choice, but to include it in the franchise.
The famous "piece of eight" was a coin that was marked with indentations dividing the coin into eight segments with two of the segments comprising a quarter of the coin. These segments could be broken off to make change. Each segment was called a bit. To this day a quarter is often referred to as "two bits", a half dollar as "four bits" and 75 cents as "six bits".
When the screen goes black, as the crew fall over World's End, the ghostly music and voices heard are directly from the Disneyland ride. Most noticeable is Paul Frees' voice of the skull and crossbones, that infamously warns passengers "Dead men tell no tales!"
The name "Barbossa" might have been derived from the real Turkish pirate "Barbarossa". Barbarossa, also known as "Redbeard", was once a pirate in the Aegean and the Mediterranean seas, before he became a Fleet Admiral of the Ottoman Empire Navy.
The flags hoisted by the pirate fleet are based on actual flags of real-world pirates. We see (in no particular order) the flags of: Christopher Moody (red flag with a winged chalice, arm and knife, and skull on crossbones), Thomas Tew (an arm with a cutlass), De Vranck (a man clubbing a skull and crossbones), Bartholomew "Black Bart" Roberts (a man dancing with a skeleton, who holds a spear), Edward "Blackbeard" Teach (a skeleton holding a spear, stabbing a red heart) is barely shown just before the flag of Bartholomew Roberts is hoisted, and Edward Low (a red skeleton). The flag hoisted by the Black Pearl is that of John "Calico Jack" Rackham (a skull and crossed cutlasses).
The climactic sea battle was shot in an air hanger at Palmdale, California, where the cast had to wear wetsuits underneath their costumes on angle-tipped ships. The water-drenched set was kept in freezing temperatures to prevent bacterial infection.
The cast and crew filmed off of the coast of Southern California in the South Bay Area around the last week of August 2006. The Black Pearl could be seen sailing to and from port from the Palos Verdes Estates and Redondo Beach pier. The stars of the film would take time off from shooting to meet fans and sign autographs.
The Singapore city was constructed out of forty buildings within a tank that was 24 meters (78.7 feet) long, 40 meters (131.2 feet) wide, and one meter (3.2 feet) deep. Since not much is known, historically, about eighteenth century Singapore, the filmmakers based the set design on Chinese and Malaysian cities of the same period, and also worked in an Expressionist style.
The crew built a sixty foot replica, of the front half of the Black Pearl, on the back of a semi trailer, in the salt flats of Utah, for a shoot with the Shadow of the Pearl. The shoot was scheduled for nineteen days, it took four.
The film's running time was originally three hours, and even though Jerry Bruckheimer claimed the long running time made the final battle work in terms of build-up, he decided to cut it down by twenty minutes.
During his monologue to the Pirate Brethren Court, Jack Sparrow employs a combination of two Latin phrases used in law: "Res ipsa loquitur", literally meaning "The thing speaks for itself", which is used when the circumstances are so obvious as to need no further evidence or explanation; and "Tabula in naufragio", literally meaning "A plank in a shipwreck", relates to priorities in loans and mortgages provided by separate loaners, such that the third mortgagee obtains the first mortgage, thus squeezing out the second mortgagee's priority for debt satisfaction. Metaphorically it refers to the last option that may prevent failure or catastrophe in dire straits.
The dog with the keys shows up at the pirate council meeting. When Pintel and Ragetti ponder how, since they last saw the dog being chased by cannibals, Captain Teague tells them "Sea turtles, mates". Sea turtles are frequently mentioned in the franchise to explain miraculous escapes.
According to Gore Verbinski, the Singapore scenes were intended to parody spa culture. A naturally humid atmosphere was achieved with a careful combination of lighting equipment and gallons of water, and fungi were allowed to grow within the set, to enhance the mood.
Hans Zimmer stated in an interview that he wrote the music for the films as if he was scoring a "biker movie", and that during the process, he substituted the ships for motorcycles in his mind when viewing the film.
About 36 minutes into the film, Jack Sparrow (Johnny Depp) says, while in the locker, "We shall have a magnificent garden party, and you're not invited." In Alice in Wonderland (2010) and Alice Through the Looking Glass (2016), Depp portrays the Mad Hatter, a character known for his garden parties.
When Jack says, "I've never actually met the man Pizzaro, but I love his pies," he was referring to a Pizzaro Pizza in Indialantic, Florida. His sister lived not too far away, and they went there for pizza.
The Black Pearl itself, while docked in San Pedro Harbor, was used to film an ad for the movie and a contest called "Party on the Pearl". Using some of the movie's cast, the ad starred Martin Klebba, Spencer the monkey, David Blue, and Jeremiah Hu.
Several times during the film, sugar cubes are seen being used when drinking tea. The plot assumes the currency of the East India Trading Company, which places the timescale pre-1858. Sugar cubes were invented in 1841 by Jakub Krystof Rad, and the depiction of their use in this film is therefore correct.
Tia Dalma says "poor unfortunate souls". Ursula, the sea witch, sang the same thing in another Disney film, The Little Mermaid (1989). The flotsam and jetsam at Shipwreck City may also be an in-joke to Ursula's minions too.
In the novelization, Elizabeth doesn't know if Will is any different from Pirates, and doesn't know if she can trust him anymore. She also lost some respect for Norrington, when he handed the heart of Davy Jones to Lord Cutler Beckett, to regain his standing in the Navy, but he never stopped loving Elizabeth, in spite of her love for the pirate's life.
The scene, in which Elizabeth Swan (Keira Knightley) is forced to remove and hand over all her weapons before entering Sao Feng's bathhouse, mirrors a similar scene in Mad Max: Beyond Thunderdome (1985), in which Max (Mel Gibson) is forced to remove and hand over all his weapons at the entrance of Bartertown.
The trivia items below may give away important plot points.
The farewells Elizabeth receives from the pirates echo their greetings and farewells in Pirates of the Caribbean: The Curse of the Black Pearl (2003): - Pintel, who met Elizabeth with "'ello poppet," says "'Bye poppet" to her; - Captain Barbossa, who first thought Elizabeth was "Miss Turner", calls her "Mrs. Turner". Elizabeth tells Jack Sparrow it would never have worked out between them, which Sparrow had earlier told her.
The sword that Will made for Commodore Norrington in Pirates of the Caribbean: The Curse of the Black Pearl (2003) has an interesting role throughout this one: Becket returns it to Norrington upon his assignment as Admiral. Norrington stabs Davy Jones with it, as his answer to Jones' question "Do you fear death?" Jones takes it ("Nice sword!") and uses it in the final battle. Sparrow knocks it from Jones' hand during the battle, to the deck of the Dutchman, where it is found by one of Beckett's soldiers. While admiring it, this soldier is killed by Jones, who takes it back, and later uses it to stab Will Turner through the heart. The sword is last seen in Will's chest as his father goes to remove his heart for the Dutchman's chest, but it has been rumored that when Will and the Dutchman return, Will has this sword at his waist, and this is the sword in the sand on the beach (along with Elizabeth's) at the end.
At the end, back at Tortuga, when Jack figures out that Barbossa stole his ship, and gets slapped by the two women, Scarlet and Giselle, look at Jack's waist. He has his "mum" tied around his belt (the shrunken head).
Prior to dissolving into a swarm of crabs, Calypso shouts a French incantation, which in the script reads: "Malfaiteur en Tombeau, Crochir l'Esplanade, Dans l'Fond d'l'eau!". This roughly means "Across all the waters, find the path to he who wrongfully entombed me!"
The pieces of eight, as seen in the film, are: Ragetti's wooden eye (Barbossa), a miniature wine cup (Ammand the Corsair), a jack of spades playing card (Capitaine Chevalle), a cork in a broken rum bottle (Captain Vallenueva), a pair of glasses (Mistress Ching), a pair of tobacco shears (Gentleman Jocard), a tusk fragment (Sri Sumbhajee), a pendent (Sao Feng, later Elizabeth Swann), and an old coin from Siam (Jack Sparrow).
The character, Tai Huang, the leader of Captain Sao Feng's crew was played by Reggie Lee. Lee was earlier seen as "Headless", the cone-shell headed member of Davy Jones' crew in Pirates of the Caribbean: Dead Man's Chest (2006) - best remembered as the pirate whose head is knocked off by a coconut thrown by Jack Sparrow, after which the decapitated head tries to direct its body around by telling it which way to look. Headless makes a short appearance in Pirates of the Caribbean: At World's End (2007) during the Maelstrom battle scene; Jack shoots the chest out of Davy Jones' hand. The chest then falls on Headless' head, and he stumbles backwards and falls overboard. This places both of Reggie Lee's characters on two different ships that are both present at the final battle.
Two major plot points, Governor Swann learning the truth about Jones' heart, and the cause of the original loss of the Black Pearl, are revealed in the deleted scenes. Number one occurs when Beckett and Norrington first board the Dutchman. Cruelly, Jones tells Governor Swann that Elizabeth is dead, so he tries to stab the heart and Jones mockingly tells him what would happen if he did. Number two occurs in an extended cut of the discussion between Lord Beckett and Jack. It is revealed that Beckett had a deal with Jack to steal some cargo, that turned out to be slaves, so when Jack set them free, Beckett burned and sank the Black Pearl, and branded him. In the scene, Beckett is amazed to see the Pearl afloat, and says that Jack paid "a heavy price" to have her back.
At the end of the film, many characters end up the same way they were at the beginning of the first film. Jack is in a dingy, Will and Elizabeth are not together, Gibbs is sleeping on the ground, and Barbossa is the Captain of the Black Pearl, with Pintel and Ragetti as part of his crew.
At the end of the film, Barbossa suggests to his crew that they go looking for the Fountain of Youth, but is prevented from doing so, since the relevant portion of the map has been stolen. Next, we see Jack Sparrow in his dinghy, turning the rings of the map to form a chalice, and the (assumed) location of the Fountain of Youth marked by an X. Judging from its position on the map (and remembering the relative inaccuracy of the mapping techniques of the day), the X lies over the Everglades, roughly thirty miles southwest of Lake Okeechobee.
A "piece of eight" is a silver coin used as currency in eighteenth century Spain. In the film, the "piece of eight" is a relic that identifies a Captain as one of the nine Pirate Lord of the Brethren Court.
When Elizabeth Swann is named by Tai Huang (Reggie Lee and Sao Feng's crew as their Captain, after being asked by Davy Jones aboard the Dutchman, the "Singaporean" crew speaks Mandarin (Chinese). When Norrington breaks Elizabeth and the crew out of the brig, Tai Huang speaks Mandarin to the crew when Elizabeth nods for them to leave.
In the novelization, Jack's final appearance is during the sandbar scene. In fact, the ending in the book is drastically different from the film. The book ends just as they're about to go into combat with the East India Trading Company, so the audience doesn't see Barbossa marry Will and Elizabeth in battle, the death of Lord Cutler Beckett and Davy Jones, or the search for the fountain of youth, which forms the plot line for Pirates of the Caribbean: On Stranger Tides (2011). The last line of the book is Elizabeth calling them the Pirates of the Caribbean.
About 32 minutes in, at the waterfall scene, right after the boat falls off the side and it fades to black, you can hear a voice saying "dead men tell no tales", this is an obvious reference to the ride in Disneyland
