Visible crew/equipment: At the blacksmith shop, after Will grabs the sword out of the fireplace just as he and Jack begin to duel around the post, in the wide shot, black straps with attached wire cables are clearly visible around both Johnny Depp and Orlando Bloom's right ankles. (This is only visible on the video version).
Visible crew/equipment: As Will and Jack duel up top in Brown's shop, in two close-up shots a large plank is visible at their feet with two long black marks along each side detailing where the beams are supposed to be, so that Orlando Bloom and Johnny Depp know where to land as they supposedly leap from beam to beam and feign keeping their balance. (This is ONLY visible on the video version.)
Revealing mistake: Aboard Interceptor, Jack calls out, "Monkey!" as the monkey jumps onto the broken mast leading to the Pearl and Jack runs after him. In the very next shot of Elizabeth, who's trying to move the broken rigging from the hatch that Will is trapped under, the coloring is off in this one shot. The color of her dress, for example, is not vibrant, it is brown. This is visible on the region 1 DVD and on videotape.
Visible crew/equipment: During Jack's escape, he swings about on the rope. As he does, in the shot immediately following Jack's first close-up, the film crew's blue flat-topped boat, as well as their speed boat with its trailing wake, are both visible at the bottom left of the screen. (This is ONLY visible on the video version.)
Visible crew/equipment: As Norrington and his men board the Dauntless he says, "Search every cabin, every hull down to the bilges." In the next shot a crew member with a white baseball cap and green shirt is actually visible hiding under the gangplank. (This enjoyable shot is ONLY visible on the video version.)
Continuity mistake: As Will holds the sword above his head to block Grapple's grapnel, the cloth (the same one he wears around his neck when his sleeve is pulled down) that is tied around his right wrist is visible. He is soon rendered unconscious by a pirate's candlestick. When he wakes he puts his right hand to his aching head and the cloth's knot is visible. The cloth is wrapped completely differently in the two shots, though he never had the chance to change it.
Continuity mistake: While standing near the Aztec chest, Will says, "He didn't waste it," and in this shot there are two buttons closed on his vest, over the belt buckle. Yet, in the close-up of Will's hand dropping the two pieces of gold, there is only one button closed on his vest, over the buckle.
Continuity mistake: When Elizabeth is taken captive and escorted to the Black Pearl to meet Barbossa, the Moon comes out from behind the clouds, her captors should have changed into skeletons. They were escorting her to the ship and would have been exposed to the moonlight. Elizabeth should have first noticed then, not when Barbossa explains it to her later.
Revealing mistake: When Barbossa cuts Elizabeth's hand her nails are short. When Will rescues an unconscious Elizabeth at the cave, she reaches for the medallion and her nails are longer. When Will ties the cloth around Elizabeth's hand and she gives him the medallion, her nails are short. However, when Jack says, "Ahh, where's dear William?" her nails are now manicured and much longer. Once she's marooned on the island her nails are short again. Most scenes were filmed out of sequence, hence the difference in nail length. Her nails should have been kept the same short length for the duration of filming.
Visible crew/equipment: During the cannon attack on the harbour near the beginning of the film, a spring board, used to propel one of the stuntmen dressed as a sailor into the air, is visible during an explosion near the dock.
Continuity mistake: A bit after Jack says, "You need to find yourself a girl mate," Jack tosses a mallet at Will. As Will ducks, in this shot the hose on both legs are rolled down to his ankles. Yet just after Jack says, "Or perhaps the reason you practice 3 hours a day...You're not a eunuch are you?" Will's hose are obviously pulled up properly. Orlando Bloom wore the hose rolled down during much of the shoot, when it was supposedly not visible onscreen. (This is ONLY visible on the video version.)
Visible crew/equipment: At her home, in the shot facing Elizabeth just as she tries to whack Ragetti with the bed warmer he grabs hold of it and camera equipment is visible at the lower left corner of the screen. Two shots later facing Elizabeth in the same angle, as she and Ragetti hold the bed warmer the equipment is still there. (This is ONLY visible on the video version.)
Deliberate mistake: Not only is the angle of the moonlight that shines through Jack's prison cell window intentionally exaggerated to enhance the shots with Jack, doggy, Koehler and Twigg, but in relevant shots, the moonlight is not seen coming through the window or the broken wall. Nor is it reflected on the floor outside the cells or in the cell next to Jack, particularly in the shots from the dog's POV looking up the corridor towards Jack.
Continuity mistake: When Jack first confronts Will at the blacksmith shop, seen behind Jack, hanging on the stone wall near the fireplace are iron masks and other paraphernalia. Later, when Jack sprays the soot at Will, the iron masks and paraphernalia are arranged differently on the wall.
Visible crew/equipment: At the Swann home, after the shot of Will nodding to the passing butler, when Governor Swann walks down the stairs as he says "Ah, Mr. Turner," a mat is visible on the foyer floor between the chair and table. The mat is also visible when Will flips the sword. However, when Governor Swann, Elizabeth and Will leave the house, the mat is gone. (This is ONLY visible on the video version.).
Continuity mistake: At Isla de Muerta, when Will's hands are bound, Jack tosses Will the sword. In the two shots facing Will, first as he catches it then as he pushes the bald pirate, Will's hose are rolled down, whereas in the previous and following shots his hose are on properly. Orlando Bloom preferred to have the hose down during much of the shoot, when it was supposedly not visible onscreen. (This is ONLY visible on VHS.)
Continuity mistake: Aboard the Pearl, after Elizabeth begins to eat the turkey leg, in the shot facing Barbossa as he pours her wine, there is a hunk of bread with a bite taken out of it on Elizabeth's plate which wasn't in the previous shots. Problem is that it's not until three shots later that Elizabeth actually takes bread from the platter and bites into it, before dropping it. (This is ONLY visible on VHS.)
Visible crew/equipment: After Will admits to Elizabeth that he loves her, she looks over and sees Cotton's parrot sitting on the flag post. Mullroy is also watching as a black-haired crew member, wearing a short-sleeve, white tee-shirt, can be seen holding the post and shaking it with his bare arm to get the parrot to fly off.
Continuity mistake: 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.)
Visible crew/equipment: On Isla de Muerta, Barbossa yanks the chain off Elizabeth's neck, grabs her hand and in the next shot as he places the gold medallion in the palm of her hand, the crew's metallic reflector screen is clearly visible on top of the Aztec gold chest, it even moves a bit. (This is ONLY visible on the video version.)
Continuity mistake: Just before Captain Jack Sparrow threatens Elizabeth Swann, watch her medallion. In one shot the medallion is over her dress, but in the next one, it is under it again without anyone having touched it. In the following shot, when Jack puts the chain around her neck, it is out again.
Continuity mistake: Aboard the Black Pearl, Pintel and Ragetti load the cannon with the chain-link cannonballs. As the cannon fires, in this shot from outside the port hole, the rungs of the steps on the side of the ship are to the right of the port hole. This shot has been flipped. The rungs are really to the left of the port hole, as seen when they load the cannonballs into the cannon and other shots throughout the movie.
Visible crew/equipment: When Barbossa's crew are invading Port Royal, two pirates run past Will carrying loot. One whacks Will on the head with a silver candlestick. As Will falls backwards, the crash mat is clearly visible on the ground behind him. (This is ONLY visible on the video version.)
Revealing mistake: On the way to Isla de Muerta aboard Interceptor, during the storm there is a close-up of Jack's hand holding the compass. There are many other close-ups of Jack's hand in the movie, but in this particular close-up, it is not Johnny Depp's hand holding the compass. Depp's fingers are slim and normal looking, but in this close-up Jack's thumb is stout and has a severely enlarged/deformed metacarpal at the base of the thumb joint (likely arthritis).
Revealing mistake: When Jack is aboard the Black Pearl, as Will makes demands we see Jack's very grimy hands and dirt embedded fingernails. Jack dives and retrieves his sword and gun underwater, and when he does the hands that lift the sword and gun underwater are perfectly clean and have very well manicured fingernails. Once on the island, his hands are as grimy as they were on the Pearl and his fingernails are once again short and dirty.
Continuity mistake: At Port Royal, Jack attempts to escape by holding Elizabeth hostage. After she puts his hat on in the first shot, while their bodies are extremely close, her right arm reaches under his left arm to go around his back in order to put the strap with the buckle on. Yet, in the next close-up, they haven't moved but now her right arm is over his left shoulder. Quite impossible between shots.
Continuity mistake: Will goes to the fort the morning after the pirate rampage in Port Royal. Will says, "We have to hunt them down. We must save her," and his shirt collar is very crooked. Governor Swann says, "If you have any information concerning..." and in this shot Will's collar and vest are straight. In the following shots the shirt collar is crooked again.
