Continuity: On the Black Pearl, just before Elizabeth spins the wheel on deck and knock's off Grapple's skeletal head, when she first approaches the wheel, it is fully wound up with rope. As she starts to spin the wheel, there are only about five lines of wound rope, next to the wheel.

Continuity: When Jack dives in to save Elizabeth, his hands are relatively clean. Yet, back on the dock as Jack rips off her corset, his hands look as if he dipped them in oil and mud.

Factual error: Viracocha is sculpted on the "Aztec" chest of golden coins, but is not an Aztec god.

Factual error: Ragetti gets hit in his wooden eye with a fork, which would cause enough damage to be noticeable but no damage is ever visible.

Continuity: Aboard Interceptor, Will points his sword at Jack, and Jack swings the boom that slams into Will. In the side wide shot as the boom comes toward Will, when we see Will's hands as he grasps the boom, he is not holding the sword, nor do we see it drop or see it on the deck; however, we do hear it hit the deck. In the next shot, Jack picks up Will's sword near the line and rail, where it didn't exist in the previous shot.

Continuity: Jack says, "That is a wonderful trick. Except, once again..." as he walks down the sloped cart. Behind him to his left are a chair, a barrel and between the two is a miniature ladder and some objects leaning on the wall. When Will cuts the rope of the overhead barrels, Jack (stuntman Tony Angelotti) stands on the cart and the ladder and other objects are not leaning on the wall between the chair and barrel.

Continuity: Jack removes Anamaria's hat, in the front shot her hair falls down, and in the next back shot, her hair falls again. Also, the striped scarf around her forehead changes in the arrangement of the stripes in different shots. In the front shots the yellow stripe is on top, but in the side shots the grey stripe is on top.

Factual error: Sir Charles Wheatstone, an English physicist (b.1802 - d.1875), invented the 'concertina' around the mid 1800's. The 'concertina' is a small musical instrument like an accordion, with bellows and keys. During the Moonlight Serenade scene, when Elizabeth walks out onto the deck, she sees the skeletal pirates for the first time, and Jacoby is seen playing the 'concertina', but it was not invented yet.

Revealing: At the dock in Port Royal, in the close-up as Jack makes his escape from the Marines, he is standing on the beam as he throws his shackle chain over the rope. The ledge to his left, just under the rope, has a metal support that is flush with the wood's edge. In the next wide shot as Jack starts his descent down the rope, the ledge and its metal support are not the same as in the close-up, they are obviously very different.

Visible crew/equipment: Aboard Dauntless, when Will says, "Here they come," behind him the deck can be seen. Then when the grapnels are being swung over Dauntless' rail by the Marines, very taught lines inches above the deck are seen going through the balusters of the rail leading to Interceptor. The taught lines were not placed by the Marines, only the grapnels, nor were they placed by Will and Jack. As Norrington says, "Set top sails and clear..." those lines going through the balusters aren't in this shot. These lines are the 'real' lines used by the crew's marine-unit for set up of the separation of the two ships.

Continuity: At the blacksmith shop, one end of the cart that Jack and Will duel on later is resting on a wood bench. In the close-up shot of their feet, just before Jack says, "Ta," the edge of the cart is flush against the edge of the bench. In the wide shots, before and after, the edge of the cart is in the middle of the bench. This has nothing to do with the angle of the camera.

Continuity: Elizabeth's maid runs out the front door and the camera pans inside. Elizabeth is seen running past the set of three large windows on the landing, as she continues towards the last flight of stairs closer to the main floor. In the next close-up though, it shows Elizabeth followed by Pintel running down the stairs that are closer to the second floor which we see behind Pintel. Additional reference can also be seen when Elizabeth initially runs upstairs away from Pintel and Ragetti.

Revealing: In the close-up of Jack as he swims to get his gun, etc, his left sleeve is pushed up and it's very obvious that he's wearing something with short sleeves under his white shirt. This isn't part of his white shirt. He has nothing on under his white shirt at any other time. (The underwater close-up of Depp was filmed in a tank at Long Beach along with the close-ups rescuing Elizabeth earlier.)

Continuity: Before Jack says, "Ta," there's a close-up of their feet and there's a 2x4 edge on the cart. Later, Jack tosses the mallet at Will, who ducks down, the cart's seen and there are two strips of wood as the edge. When Jack flips a plank, it smacks Will in the face, he falls and that end of cart's seen and now there's no finished edge. When the barrels fall on the edge of the cart, we see the 2x4 edge again. In many shots throughout the scene the edge changes. Also, in a couple of shots the edge has a cut out in the corner, for the wire they used. (The wire can be seen on Disc 2.)

Continuity: After Jack's attempted hanging, Will and Jack run with the rope and after knocking down the first three soldiers, they encounter another two at the stairs. In the first side shot, the two Marines trip over the rope empty handed and are almost at the ground. Yet, in the next front shot they are just tripping over the rope and they both have swords in their hands now. Also, Jack is higher up on the steps in the second shot.

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: The hangman hits the rope on the wood beam, but the blade doesn't embed itself in the wood, the way it's in the subsequent shots. After Norrington looks up to see the hangman's about to fall on him, in the next front shot, Will pushes the hangman toward the crowd and he starts to raise his arms. Here the axe is embedded perfectly perpendicular in the wood beam. As Jack and Will run with the rope, the axe is seen behind them and it's not at all embedded in the wood as in the earlier shot. This is not because of the angle of the camera.

Continuity: When the hangman's axe actually hits and cuts the rope, in the very next shot the view of Jack is between the hangman's right leg and the wood brace. In that shot, we see Jack start to go down and on the right, we see Will getting up right next to the hangman. Next are close-ups of the rope coming loose, Jack falling and Norrington pushing through the crowd. Then in the next shot of Will, he is just now getting up and then lunging at the hangman to push him over.

Continuity: Aboard the Interceptor, after Elizabeth lifts the hatch and comes up on deck, Anamaria says, "The Black Pearl. She's gaining on us." In the very next shot of Elizabeth, behind her on deck is the crewman with the tan hat. In the next shot as she looks out towards the Pearl, up at the top of the rigging are two crewmen, one of them is the same crewman that was just on deck in the previous shot. He's the one who stands on Cotton's left in Tortuga when Jack inspects the "able-bodied crew."

Deliberate "mistake": After Will and Jack swing aboard Interceptor, Will cuts four lines from the belaying pins on Interceptor, that lead up to Dauntless and each line snaps back. As Interceptor pulls away though, we see other lines that are still connected to Dauntless, but then the shot cuts away. Because of a mishap during filming, it was the only shot Director, Gore Verbinski had of Interceptor pulling away from Dauntless.
