Revealing mistake: Will slides down the sail, aided by the knife. At the start of the next shot, when he grabs hold of the mast line, the cut in the sail runs the the bottom edge of the sail, yet, Will is actually seen falling from the top of this shot - way above the end of that knife cut.

Revealing mistake: The long bamboo pole lies directly at "Chief" Jack's back whilst he is bound by the rope. However, when Jack escapes and runs, in a few shots there is a distinct outline of an apparatus at his back - under the vest, with which the pole lies higher up, away from the actor's back.Super Grover
Revealing mistake: In the first scene where we see Elizabeth talking to Jack on the deck of the ship, you can tell that Elizabeth is wearing a wig. When she turns to Jack, the wind blows her hair over the front of her shoulders, and you see her real (very short) hair on the back of head. When it cuts back to an over the shoulder shot of her, her wig is now covering her real hair.
Revealing mistake: When the fruit from Jack's "kebob" lands next to him, they gently plop to the ground intact, despite having fallen from a great height. Although Jack also lands intact, his fall was cushioned by a number of obstacles - the multiple wooden bridges, the bamboo pole catching between the rocks, the unwinding rope, etc. With the exception of the pineapples, the already-damaged fruits (from being speared) are too thin-skinned or the rinds too brittle to have survived an impact from the height, speed, and angle shown. These are the SAME fruits (papayas, mangos, and melons) that easily splattered into pulp when thrown at Jack by the native women with far less force, a slower speed, and at a close range.raywest
Revealing mistake: When Jack, Elizabeth, Norrington and the crew are sailing to meet the Dutchmen, you can see the water is moving past the Pearl, showing the Pearl in motion on the water. There is then one shot of Elizabeth and the sea behind her is completely still and not moving past the Pearl. Camera cuts and again the sea is moving past the Pearl.A Demon
