Continuity: When Jack says "If you can spring me from this cell," there are suddenly no bars in front of him anymore. In several shots before this, we see him talking to Will without seeing bars in front of him, but he is still at a fair distance so that it makes sense to put the camera in front of him. But in this shot we actually see the camera move with his face, and we see a bar disappearing to the right, so the camera is on Will's side of the bars, and suddenly we see Jack without bars between the two. (The hole would actually be so big he could get through it and escape.)

Continuity: When the Pearl chases the Interceptor the sea changes frequently from rough, to (relatively) calm sea. That cannot change that rapidly.

Other: When we see Jacoby lying face down with the axe in his back, we can see how far the axe sticks out. It's not deep enough in his back to stick out with that weight of wood and metal. That axe would never stand upright, it would fall to the side.

Other: When Jack looks at the Pearl from his prison window, he is at least 10 boat heights above the ship. As we see throughout the movie when we look at the cannons of the Pearl and how they stand on the floor and shoot through the openings of the ship, there is no way that they could be rotated upwards to shoot as high as would be necessary to hit the prison cell.

Revealing: The cannonballs are solid balls and not self-exploding cannonballs (as can be seen from the handling on board of the Pearl). As such they cannot explode when they hit a target. Even if they were self-exploding cannonballs, they would simply explode and not cause yellowish fire flares around them. The type of fire that is seen after impact comes from a liquid, not anything made of powder (particularly noticeable with the cannonball that hits the prison that lets the prisoners escape).

Continuity: Barbossa's scar changes appearance several times during the movie. At times it's almost completely gone, and sometimes it's even quite "thick".

Other: When the Interceptor reaches the "boat graveyard" just off the dreaded island, it hits a pole or other assembly from another boat underneath them. It then "falls", literally plummets, downward and hits the ground with a thud. But wood doesn't "fall" downward through water, in fact, most wood swims. Even with other metal or other objects attached to it, this whole piece/assembly would have to be solid lead to "plummet" at that speed through water. No matter what the material is, it cannot go down that fast through water.

Continuity: In the overhead wide shot of the Pearl pursuing the Interceptor they are maybe three boat lengths apart. Before and after they are further apart. In general during that entire pursuit sequence their distances change too rapidly, from nearer to farther away (as seen from either ship towards the other), but that shot shows a particular discrepancy.

Visible crew/equipment: Just as Jack says, "On deck, you scabrous dogs," to the very left edge of the screen over Jack's shoulder is a grip crew member with a tan cowboy hat, white short sleeve tee shirt and sunglasses, just standing there looking out to sea.

Revealing: When Jack holds the chain to Elizabeth's neck, and subsequently swings about, there are about ten links between the wrist shackles. When he tosses the links over the rope, before he slides down, there are at least fifteen attached links. Then at the blacksmith shop, when Jack sits at the anvil, there are eight links, and after he breaks it there are three links dangling from the right shackle and seven dangling from the left, totaling ten.

Factual error: During Jack's sliding down the rope scene, it is very noticeable that each one of the English soldiers fire their weapons more than once, which is impossible for that time, knowing that repetition weapons weren't invented until the mid 1800's.

Revealing: Either the first shot has a gratuitous view of the fort or the composite people neglected to add the fort in the second shot. Norrington says, "...this is the day that Capt. Jack Sparrow almost escaped. Take him away." The night shot that follows, shows the bridge archway, and beyond it the pier, Interceptor, the fort and its parapet. After Will breaks Jack out of prison, they approach the same archway and beyond it is the pier and Interceptor, but in this shot we don't see the fort and its parapet, nor the line that Jack slid down the day before. The camera angle is exactly the same.

Visible crew/equipment: When the Interceptor is totally blasted by the explosion of the gun powder deck and after Pintel says, "Any of you so much as thinks the word 'parley,' I'll have your guts for garters," just when Elizabeth goes under the rope, one can see a man with headphones on his head and a megaphone in his hand in the lower left corner of the screen - it looks like Gore Verbinski, the director. [This is only visible on the video version - someone sent me a screenshot as proof, but taken via a digital camera, so not really postable quality. Can anyone provide a better image?]

Visible crew/equipment: At the blacksmith shop, Jack and Will start to duel and Jack asks, "But how's your footwork?" In the next close-up shot of their feet, the imprint of a modern, flat bottom trainer/sneaker sole can be seen on the dirt floor at the bottom right of the screen. It is not the imprint of a heel and sole of the time period. As a point of interest, on the video version of this film there are multiple imprints visible!

Continuity: When Will delivers the sword to Governor Swann, watch the clock on the wall. While Will is waiting, the time is 09:45am. When Gov. Swann enters the room, the time is 09:40am.

Continuity: Aboard the Pearl, in the close-up of Elizabeth hiding the dinner knife in the napkin, the base of the decorative embossed silver knife handle (area of bolster, where the blade meets the handle) is flat all the way around. However, oddly enough, when she stabs Barbossa moments later, in the close-up of the knife protruding from Barbossa's chest there are two wide ridges circling the base - obviously a different knife.

Revealing: When the Black Pearl swings alongside the Interceptor for the battle, Elizabeth shouts, "Fire all!" The next shot is from behind the lit cannon which is aimed at the Pearl and the following shot faces the Interceptor's cannon, as it goes off. In the shot facing the Interceptor, the raw wood scaffolding type beams are perfectly visible at the entire lower part of the screen, where the painted planks (below the gun ports, above the bilges) of the hull should be. (This is ONLY visible on the video version.)

Revealing: After Gillette locks the shackles on Jack's wrists, it is clear in Jack and Elizabeth's close-ups that the wider side of the shackles' distinctively shaped straight bar faces out at his wrists. However, when Jack is in the blacksmith shop, sitting at the anvil trying to break the links, the left shackle is actually around his wrist the opposite way! (This even occurs in other consecutive shots.)

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.

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.
