Continuity mistake: This occurs during and after the scene where Jack empties the sand out of the jar and puts the heart inside. After replacing most of the sand, in the later shots the amount of sand in the jar keeps changing. Later in the scene on the Black Pearl, the amount of sand changes from shot-to-shot up until the jar is dropped and breaks. (01:51:40)
Continuity mistake: When trying to flee, Norrington falls and drops his sword and the chest. As he crawls in the first shot, note the sword's hilt and particularly the hand guard, with its wide part facing up. In the next shot the direction of the hand guard has changed, with its wide part now facing the ground (this has nothing to do with camera angle). (01:58:45)
Continuity mistake: When Pintel and Ragetti argue over the pronunciation of "Kraken" while they're rowing, the loose end of Jack's red bandanna changes position and jumps from his back to over his shoulder, between shots more than once. (01:38:30)
Continuity mistake: In the scene where the two sailors have found Jack's hat in the water, they try it on in turn. When the second man tried it on, the hat changes position between shots, with no time for him to move it. In one shot, one of the corners is facing front, in the next shot a flat side is facing the front. (00:17:50)
Continuity mistake: At the end of the film in Tia Dalma's hut, when Tia is handing out drinks, just before Gibbs gives his two cents about Jack, there is a wide shot of the whole group and Gibbs can be seen pushing away from the doorframe and standing up. The camera cuts to a closer shot of Gibbs, and he pushes away from the doorframe a second time.
Continuity mistake: In Tia Dalma's shack, when Tia Dalma approaches Will saying he has a touch of destiny about him and that he wants to know her, Will was standing in the door and took a few steps forwards, his back to the door. But when Jack runs to separate them, if you look through the gap between Tia Dalma and Will, they are now standing sideways to the door. (00:49:00)
Continuity mistake: When Tia Dalma holds the tray with two candles and a mug (the others were given out), as she asks if they would be willing to do anything, the position of the mug changes between shots.
Continuity mistake: After Jack seasons himself, in the first shot as the cannibals carry him, the rope is wound around his body and ankles, with the excess rope in between that hangs over the pole from his right to his left. When he is placed over the kindling, that rope hangs over from his left to his right. Also seen when Jack tries to blow out the flame. (This has nothing to do with camera angle.) (00:35:30)
Continuity mistake: When Captain Bellamy and his sailors stand on deck, looking at the flaming Tortuga, their positions differ between the shot facing them and the next shot, from behind. (01:07:10)
Continuity mistake: During Jack's escape, as he attempts to flee from the cannibals, when he enters the hut there are silver objects, such as tea pots, etc, on the table, which change position in following shots; and the cup and saucer disappear in the shot facing the table. (00:33:40)
Continuity mistake: When Jack, Elizabeth and Norrington remove the small chest from the larger one, and when Will kneels beside them, there are letters, etc lying on the large chest's lid, which change, disappear and reappear. (01:41:20)
Continuity mistake: When Norrington walks into Beckett's office, things on his desk change position between shots. (02:11:00)
Continuity mistake: When the cannibal women throw fruit at Jack, the large papaya hits the pole's point and the end of the fruit actually smashes. However, in the next shot it slides across the pole with a perfect circular hole. (00:41:05)
Continuity mistake: When Will is speaking with Cutler Beckett, Will's knotted bow tie changes - note the level of its white lace. (00:10:00)
Continuity mistake: Aboard the Flying Dutchman, when Will sneaks in to steal the key, as the shot draws closer to Jones the quills are shown on the organ keys - with one leaning over the keys. In the next shot, as Will reaches sleeping Jones, both quills are leaning away from the keys, and an extra quill stick (feather free) suddenly appears. (01:24:00)
Continuity mistake: When the Flying Dutchman attacks the Pearl the cannon flies through the rear windows and slams into the captain's stateroom doors, leaving a debris laden door jamb. However, in the next shot when Pintel and Ragetti peer in, the door jamb is intact. (01:56:20)
Continuity mistake: After Jack has escaped from the island where he was going to be burned, the makeup on his face (the eyes) changes between scenes. The makeup has faded quite considerably when he first boards the Black Pearl then in a later scene the makeup is neater and clearer. (00:42:30)
Continuity mistake: After Jack explains the legend of Davy Jones to Elizabeth, and they have found their heading, Elizabeth's braid is going down her back. When Jack points Elizabeth toward the ship her braid is now on her right shoulder. She doesn't move her head and there is not enough time for her to move it herself. (01:17:00)
Continuity mistake: When bound Jack begins his escape, he happens upon a young cannibal boy holding utensils, whose face and body are painted. A bit later, on the beach, the paint differs greatly - note the lines, etc. (00:37:55)
Continuity mistake: When Jack "intuitively" inquires about Elizabeth's feelings, the dangling beads in his hair are over his dreadlocks, near his shoulder. Next close-up they're tucked under his hair. This type of thing - with all the do-dads in Jack's hair - occurs numerous times throughout the film. (01:35:20)
Answer: There is a scene after the credits of "The Curse of the Black Pearl": the monkey got back to the cave and took a coin. That way he turned undead again.
