Continuity: In the close-up of young Elizabeth, as she sings on the bow of the ship, she's standing between two posts of the railing. Each post has rope wound around it. In the next few shots of her, the existence, the amount and the thickness of the rope on each post changes drastically.

Continuity: As young Elizabeth sings, the next shot from behind her to her right we see the cannonballs lined up at the bottom of the rail going around the deck. When she yells out, "Look! A boy..." Now there is a cannon in the corner of that bow.

Continuity: In the beginning, after the young Will is pulled on board, when Will says his name, the medallion is protruding out of his shirt. After young Elizabeth tells him, "I'm watching over you Will," in the next shot of Will, the medallion is completely hidden in his shirt, and his position differs between shots.

Continuity: When young Elizabeth holds up the medallion, and she sees the Black Pearl, her fingers are positioned differently in the wide shot and in the close-up shot of the medallion.

Continuity: Will's facial hair darkens quite a bit in the time it takes him to walk from Elizabeth's house to his blacksmith shop. (The sword scene in the Governor's mansion was the first scene that was filmed with Orlando. His facial hair was not fully grown in because he had just arrived on set. On commentary.)

Continuity: When the coach leaves, Will walks down the steps. Both side gardens are edged with stones outside the front door. The driveway is also lined with the stones. When the pirates invade their home, Ragetti yells, "Up there." The front door's open and the stones are now lined up parallel to the front of the doorway, just past where the steps should be. Even if it's meant to be the stones lining the opposite end of the driveway, the distance of the far side and proportional size of the rocks are wrong.

Continuity: When Jack jumps down from the mast yard arm on the Jolly Mon to bail water, in the far wide shot, the mast pennant lies still, yet blows wildly in the previous shots and the bottom left of the sail is caught up on line from the rigging, but in the following shots, it's not. Also, in the wide shot he starts to walk to the middle of the boat, and he puts his arms out as he's starting to pass to the right of the mast. In the next close-up of Jack, he's passing the mast on the other side.

Continuity: When Jack sails toward Port Royal, he passes the skeletal remains of hanged pirates, to whom he pays a respectful bow. First, there are two wideshots of the skeletons, then in the close-up they are actually wearing more clothing, particularly the strapping middle guy, whose head position differs, and his straw hat is larger as well.

Factual error: Near the start, Jack steps from the yardarm of the sinking craft onto the dock. However, as it is a sailing craft, there is no way that it could have continued its forward movement once the sail was under water, even discounting the drag effect that the sail would have had in the water. Once the sail is submerged, it would act as a type of anchor.

Continuity: When the sinking Jolly Mon 'sails' towards the dock, the straw basket which sits on the dock changes positions in the following shots, as does the rope lying on the side of the dock. When the dock master says, "It's a shilling to tie...dock," they look at what's left of the boat. The flag is hanging straight down, not blowing, but after Jack says, "And we forget the name," the flag is now wrapped around the mast. The following is only visible on VHS: there is one large barrel directly in front of Jack, but when the shot faces the Jolly Mon, there are two - a small one appears, which has a paint splattered top.

Continuity: In Port Royal, as Jack passes the dock master, he says, "Hold up there you. It's a shilling to tie up your boat at the dock." In the wide shot, a man carrying bananas, (the one with white pants, white shirt, vest and hat) is passing behind Jack. Then, there's a close-up shot of Jack and a shot of the Jolly Mon. When the dock master says, "And I shall need to know your name," in Jack's close-up, that same man starts to pass behind Jack, but by that time, he should be at the gangplank already. This has nothing to do with the angle of the camera.

Continuity: Jack walks past the dock master, behind Jack the desk is on a wagon and the handle is leaning on the left side of the desk. Also the feather quill on the desk is leaning towards the back of the desk. When Jack walks away and takes the sack of money, the handle of the wagon isn't leaning on the desk and the feather quill on the desk is leaning forward towards the front of the desk.

Visible crew/equipment: When the dock master tells Jack, "Hold up there you. It's a shilling.." seen in the background on the left of the screen is a thatched roof enclosure. An orange aluminum ladder is sitting under the thatch! Many of the crew's orange aluminum ladders of various heights can be seen on DVD 2.

Continuity: At the Fort, the two columns of soldiers separate and Norrington walks into view. It's shouted, "Right about face," and the soldier behind Norrington on his left has his black bag to his side. When "present arms" is shouted, the soldier's black bag is in front. Also, Governor Swann, in the front wide shot, is standing on the second step from the bottom. In the next close-up, he's standing on a step further up - the soldier to his left in the previous shot was standing on the same step as him.

Continuity: On the dock at Port Royal, Jack is speaking with Murtogg and Mullroy, who are guarding the dock from civilians. Seen behind the Marines to their left is the vacant dock edge. Yet when Jack holds Elizabeth hostage, the same dock edge is seen, but in this shot the edge is now filled with barrels and sacks. No one was on the dock between these two scenes.

Continuity: When Jack walks down the dock to the Interceptor, Murtogg and Mullroy are sitting with sacks, crates and barrels in a deep shadow, but the sun is seen afar. A few shots later, after they intercepted him, those same sacks, crates and barrel are brightly lit by the sun. The shots were probably filmed at different times of the day.

Continuity: When Elizabeth faints and is falling into the water after Norrington's proposal, there's a shot of her from on the rock. You can see her hat and scarf falling right after. But when the shot moves to Jack and the two guards on the ship, Elizabeth is falling and there is nothing above her - where are the hat and the scarf? There is plenty of time to see the hat and scarf fall too, if they were actually included in the shot, but they simply weren't.

Deliberate "mistake": When Elizabeth falls down from the cliff, with her hat and scarf falling over her, you can see it is definitely not Keira Knightley, as the stuntperson's face is perfectly visible.

Continuity: After Elizabeth falls off the ramparts, the first shot is of an unconscious Elizabeth under water, and her right shoe is not on, at the heel. In the next two shots, the shoe is perfectly on.

Continuity: After falling off the parapet, Elizabeth is under water, and we see a close-up of the medallion floating freely, causing a tremor in the water. When Jack gets her back on shore and rips open her corset, the medallion is now firmly tucked inside her dress - no way it could have just slipped in there given how insanely tight it was.
