Continuity: During the scene where the crabs in Davy Jones' Locker are helping to move Jack's ship, the camera does a close-up of Jack's face, in which he has a very amusing expression. In the next shot, the camera has pulled back from him, and his face and angle are entirely different.

Continuity: At the end of the movie Beckett is walking down the stairs of the ship while it's being blown to bits by the cannons from the 2 pirate ships. There's a close up slo-mo shot of the railing being destroyed as he walks down. The railing is consistently being blown up RIGHT behind his hands. The shot cuts away to a view from in-front of him and there's a good 3 feet between his hand and where the railing is broken.

Factual error: In the final scene, when Jack Sparrow is looking at the map to find the Fountain of Youth. The map lists Ponce de Leon's travel date of 1523. The actual date of the Fountain of Youth founding was 1513.

Other: When the civilians are hung (beginning of film) the drop through the trapdoor is significant. All, however, have a length of rope attached to the noose, which is simply too short to allow such a drop. Furthermore, they all move up and down after the drop, suggesting an almost springlike flexibility of the rope. Their bodies would probably bounce sideways, but not up and down.

Continuity: When the Flying Dutchman and the Black Pearl destroy the Endeavor, they work their way from the front to the rear of the ship. Yet the wave of destruction is actually shown to be moving forwards along the ship following Lord Cutler Beckett down the steps from the wheel.

Continuity: When Elizabeth is making her speech to the pirates near the end of the movie her hair moves from over her shoulders in front shots to behind her shoulders in shots from behind.

Other: When Beckett walks through the ship which is being destroyed by cannon fire in slow-motion, you can see things like bannisters and railings exploding right by him, and yet no cannonballs are seen, the ship just spontaneously explodes.
