Deliberate "mistake": When Will is bound and brought before "Chief" Jack, Will says, "The compass!" and there is a close-up of the compass, as it hangs to the right of the long striped cloth. However, in all other shots the compass hangs to the left of the red and white striped cloth. This is a flipped shot - note the large buckles.

Revealing: when Pintel is running up to Ragetti during Elizabeth's rant on Isle Cruses, you can see the path in the sand where Pintel has run up in previous takes.

Continuity: After Will slides down the sail, just as he grabs hold of the mast line, the cut sail is only tied down at its corners. After he puts the knife in his mouth, the sail is also tied down directly under the cut.

Continuity: When Will hangs upside down, as he shouts, "Who wants it? I could do this all day!" his necklace dangles freely, beside his face. However, when Will is shot by the dart, the necklace is mostly tucked into his shirt.

Continuity: Aboard the Pearl, after Will orders the rum to be loaded, and Gibbs responds, "Aye, the rum too," the cloth round Gibbs's neck has the loop to his right, but in previous and following shots it's actually "tied" round his neck the opposite way, with the loop to his left.

Continuity: When Beckett says, "A marriage interrupted," he writes "Lord" as he signs the Letter of Marque, but when he places his seal, his handwriting differs.

Continuity: When Elizabeth, Will and the rest watch from the long boat, as the Kraken takes down the Pearl with Jack aboard, in the shot facing the Pearl Cotton sits directly behind Will, but in the shot facing the long boat Pintel sits behind Will.

Revealing: Will slides down the sail, aided by the knife. At the start of the next shot, when he grabs hold of the mast line, the cut in the sail runs the the bottom edge of the sail, yet, Will is actually seen falling from the top of this shot - way above the end of that knife cut.

Revealing: The crow pecking on the floating coffin Jack is hiding in has a modern-day identification band on its leg.

Continuity: In the row boat, on their way to Tia Dalma's, when Gibbs discusses the Kraken, the large tear at his shoulder is visible, as are other imperfections on the tattered vest. Later, the tear disappears and other things change as well.

Continuity: When Will hangs with his hands bound, the ruffle on his shirt cuff goes up and down and up again.

Continuity: When Elizabeth sits on deck and points out the burning word Tortuga, the wound lines beside her change position between the shot facing her and the next shot, behind her.

Continuity: In the scene early on in the movie, where Lord Beckett and Elizabeth are talking, behind Lord Beckett you can see a man sitting on a seat suspended in the air by two ropes, apparently working on a ship or something of that nature. Then, the camera cuts to Elizabeth and when it cuts back to Beckett, the man in the background is gone, and the seat or ropes are no longer there either.

Continuity: At the beginning of the film, right after Jack hands Gibbs the dead man's leg, Mr. Cotton throws Jack's coat about his shoulders, over his hair and bandanna, but when Jack turns around, in the next shot, his hair and bandanna are on the outside of the coat. No one touched them, and Jack seems oblivious to his various accouterments, so he wouldn't have done this either.

Continuity: When Elizabeth walks over to the deck rail and notices Jack sneaking away in the long boat, her leather strap hangs from her left shoulder to her right hip, whereas in all other shots she wears it the opposite way. This is not a flipped shot - note Cotton's shirt tear.

Continuity: When Elizabeth enters the carriage, after her father rescues her from prison, the bottom of her dress is quite filthy. However, when she runs out of Beckett's office, it is much cleaner.

Continuity: After the Flying Dutchman's attack on the Pearl, when the Kraken attacks the Pearl, one of its tentacles comes through the captain's stateroom stern windows, which has considerable damage - notably the left window and part of the wall are completely gone. When Gibbs says, "Abandon ship or abandon hope," the stern windows are actually more intact - especially the left window/wall.

Continuity: When we first see Jack as the "god," the multiple eyes painted on his face are sharp and defined. In the brief second shot, where we see the left side of his face, they appear worn and blurred. The third shot shows them sharp and clear again.

Continuity: After Beckett tells Will to get the compass, in the next shot of Jack aboard the Pearl, as he plots the map, things on the table - such as the compass, change position between shots.

Continuity: In the scene where Will visits Elizabeth in jail, she is rubbing his chin in most of the shots but in one shot her hand is suddenly down and then it goes back up again in the next shot.
