Continuity mistake: On the small sand spit, when Jack, Elizabeth and Barbossa meet with Will, Beckett, and Davy Jones, the leather cuff Jack wears on his right hand actually disappears and reappears twice during the meeting.
Trivia: When Keith Richards is looking up the rule in the pirate code book, the skull ring on his finger is not a prop; he has worn it since receiving it for his birthday in 1978 from a famous London goldsmith, who used a real skull when modelling the design.
Continuity mistake: When Beckett boards the Dutchman and speaks to Jones, he has very noticeable dark facial stubble, but bizarrely, in his next close-up he is actually clean shaven, his wig curl has shrunk and his eyebrow hair is neater.
Continuity mistake: The worn areas of Jack's leather hat drastically changes throughout the film. Additionally, the hat has a threaded 'X' on both its right and left side. In numerous close-ups extra thread holes are visible in different areas near each of these Xs; such as in the Locker, when Jack lies on the ground as the Pearl passes by and later, on the little island, before Jack switches places with Will. In other shots those extra holes are gone, such as when Jack sets sail for the Fountain of Youth. The actual sizes of the Xs also change.
Revealing mistake: After the military attack Sao Feng's residence, when Elizabeth is seen fighting amid the melee the black spandex-like shorts are visible under her robe as she kicks up.
Continuity mistake: Aboard the Dutchman, when Jones's crew shout, "The Admiral's dead," Norrington's black scabbard lies conspicuously at his right side, but when he stabs Jones the scabbard is gone.
Continuity mistake: When Jack begins to speak to Captain Teague, Teague's left hand is under the guitar frets, but in the shot facing Jack that hand rests atop the guitar, then when Teague says, "It's not just about living forever, Jackie," his left hand is under the frets again.
Continuity mistake: At the end, when Jack says, "Drink up me hearties, yo ho," the compass rope flips its direction, from hanging across his palm to over the back of his hand, between shots, including the compass close-ups.
Continuity mistake: At the mass hanging, when the singing begins, in one shot of the people (with the boy) standing at the gallows, the others down below, who wait at the head of the line, are also seen behind them singing. In a following shot, some at the head of the line differ.
Continuity mistake: The shape of Will's long scar is entirely different, between the time he commands the Dutchman to when he leaves Elizabeth after their day together.
Continuity mistake: Aboard the Pearl, after Elizabeth asks, "What shall we die for?" and begins a rousing speech to the crew, her hairstyle differs significantly in following shots (despite the wind).
Revealing mistake: Just after Barbossa and Elizabeth reach Sao Feng's residence, down below when Gibbs pulls the bars they actually bend.
Continuity mistake: Elizabeth has a beauty mark above the corner of her right eyebrow which actually disappears in some of her close-ups. For instance, when she is with Norrington and asks, "Know what? Which side you chose?" and later, when he kisses her. Later, in the scene with her son, the beauty mark is gone in one close-up and then just reappears in the next one, as she glances at her son.
Continuity mistake: When Captain Teague looks up the Code in the book by Morgan and Bartholomew, in the close-ups the fingers of his right hand runs across the line "It shall be the duty of the Pirate King", but next wideshot it's his left hand doing the page scanning, with his right hand at his side.
Answer: He agreed to do a job in exchange for eternal life, with a few limitations. If he refused to do that job he'd be cursed until he fulfilled his duties, but that doesn't excuse him from the details of the previous enchantment. He didn't simply choose not to walk on land, he couldn't.
