(at around 2h 20 mins) Right after the battle aboard the Dutchman, we see Jack and Elizabeth leaving with a made-up "parasail" and they land straight to the sea. In the next scene, we see them boarding the Pearl, and they should be soaking wet since they are just coming out of water, yet no water is visibly dripping off of them. Elizabeth is a little wet from the rain but Jack is remarkably dry.
(at around 35 mins) When Jack Sparrow is in Davy Jone's locker, he makes a comment about there being no wind at all, but in the shots right after that, some of his hair can be seen blowing in the wind, showing that there actually is wind.
(at around 2h) When Elizabeth is giving the rousing speech to the pirates on the gunwales of the ship, all the close up frontal shots of her show her hair partly tied up. Rear shots show her hair completely loose but damp and limp. As she jumps down from the gunwales, her hair is loose, dry and bouncy. Will Turner's hair in the same scenes sometimes appear neatly tied back, at other times flying in the wind in his face.
(at around 28 mins) When Lord Beckett boards the Dutchman with Davy Jones's heart, he has stubble on his face. When he walks towards Jones, he is clean-shaven.
(at around 1h 11 mins) When Jack is about to use the cannon to launch himself over to the Pearl, Beckett states he is mad for doing so. When Jack agrees and lights the cannon, Beckett ducks for cover twice.
Several dozen pirates running from one side of the ship to the other would neither stabilize nor destabilize the ship's balance. It would have no effect.
Sao Feng and his crew are heard using primarily Cantonese while the main Chinese dialect in Singapore is Mandarin, not Cantonese.
(at around 31 mins) During the waterfall scene before the ship goes over the side everyone is scrambling about deck. You hear at least two characters including Elizabeth give the command "Hard a port". When this film was taking place the type of commands for steering ships at sea were called tiller commands. The tiller on a ship is what actually moves the rudder and a hard to port command would have made the ship turn right and not left as it did. Tiller commands were replaced by rudder commands in the early 20th century. The modern rudder command would have made the ship turn as it did.
The chart appears to be made of individual sticks or reeds that are bound together, allowing it to be rolled up. It would be impossible to have rotating wheels in the center since, if the wheels were not aligned correctly, i.e. in parallel, the chart could not be rolled up.
At 7'53", when Elizabeth hands in her weapons and throws her coat into the hands of a guard, she flashes her belly button piercing.
(at around 10 mins) It's often believed that the founding and naming of Singapore postdate the period in which the films are set. In fact, the name "Singapura" - "city of the lions" - was first given in the fourteenth century.
(at around 4 mins) Some viewers have reported seeing braces on the teeth of the young boy singing in the opening scene. In fact, the boy has metal caps on some of his teeth, much like Jack. The only difference is, his are blackened and clearly not made of gold.
(at around 54 mins) Aboard the Black Pearl in Davy Jones' Locker, while the crew is attempting to capsize the Pearl, the charts are on a table on deck. Nowhere is it seen that Barbossa, who was standing next to them, or anyone else grabs the charts. So, when the ship capsizes, the charts would sink in the ocean along with other loose object on the ship, but we clearly see them throughout the rest of the movie. However, physics are arbitrary in the Locker.
In some close up shots, you can see the contacts that Barbossa is wearing to make his eyes appear yellow.
(at around 8 mins) When the pirates remove the grate beneath the Chinese pirates den, the grate flops around as if it's made of rubber.
(at around 2h) Just before the Flying Dutchman was to go into battle, Calypso was stirring the clouds and Davy Jones gripped the hole where his heart once was. You can see under his tentacle beard that it is his real hand gripping his chest.
At around 21 minutes, when the Flying Dutchman opens fire and the pirate ships are exploding, one ship's wheel and the support structure for it are blown from the top deck to the main deck, but there is nothing (gears, ropes, etc.) to indicate that the wheel actually turned anything. It was just a prop wheel on a mount.
(at around 2h 20 mins) When Jack and Elizabeth leave the Dutchman by way of the makeshift parachute, one can clearly see Elizabeth's hair is dry even though heavy rain, wild sea and spray are all about.
During the initial ship-to-ship battle scene, one ship's flag is not blowing on wind, however it remains extended vertically. It would either be wind blown or hang down the flag pole.
On the Asian pirate with the slice scars across his face, the scar on the left side of his face includes the top of his ear bot not the bottom (ear itself), then continues directly below the ear. He would most likely have had half his ear sliced away.
Davy Jones cut out his heart because the pain and grief caused by Calypso was too great to handle.
He even refers to himself as "a heartless wreck".
Even so, he spends a great deal of time in both the 2nd and 3rd movie being sad and melancholic, even to a point where he cries.
So removing his heart had seemingly no effect in suppressing his grief.
(at around 1h 30 mins) In the beginning of the tea drinking scene with William, Lord Beckett adds a sugar cube into his tea. The first sugar cubes were invented in the Czech town of Dacice during 1840s, decades after when the movie is set.
(at around 2h 35 mins) At the final scene in Tortuga, Master Gibbs is seen to be holding a teddy bear while in his sleep. But teddy bears were not invented till 1902.
(at around 2h) When Beckett sets the Dutchman to give no quarter in the maelstrom battle, he orders his officer to make semaphore signals to the other ship. This is done by an officer holding two flags in different positions, the modern way. However, the British Navy in the 18th century did this by hoisting sets of special flags on the masts of the ships, not by setting an officer on deck.
Prior to 1819 (when the British arrived and established a colony), Singapore would've been a tiny Malay fishing village, not a bustling port town inhabited by Chinese as depicted in the movie.
All the British Men of War in the film are painted in the "Nelson Checker" (black and yellow bands with black gun-ports). However this pattern was not common until 1805 when used by Admiral Nelson.
(at around 26 mins) When Davy Jones is playing the organ, the music is a scale going down, but his tentacles move up and down on the keyboard, not matching the pitches of the music.
Singapore Harbour as depicted in the film is apparently surrounded by mountains. In reality, Singapore is a small, flat island whose highest point is Bukit Timah, standing at a mere 164 meters above sea level.
The triangular hats worn by the citizens of Singapore are actually Taiwanese in culture and are not worn by Singaporeans.
If Barbossa started off as Jack Sparrow's first mate, then he would not have been a pirate lord and would not have had one of the nine pieces of eight unless he took it from Jack Sparrow prior to marooning him on the island (referenced in the first POTC). However, it is shown that Jack Sparrow still has one of the nine pieces of eight. How did Barbossa, as a mutinous first mate to Jack Sparrow, become one of the pirate lords and have one of the nine pieces of eight?
It is said that Davy Jones cut out is heart, after he felt betrayed by Calypso, but already on his duty.
This was a very personal choice, made by Davy, and does not belong to his duty to be captain of the Dutchman.
So there is no sense in Will Turner, having his heart cut out, during the procedure to make him the new captain of the Dutchman later.
So there is no sense in Will Turner, having his heart cut out, during the procedure to make him the new captain of the Dutchman later.
In order to control Davy Jones, Beckett sends men on to his ship (Norrington and the two guards for the chest). Since the Dutchman frequently submerges, how would they survive?
The Endevour is a first rate ship of the line. This means that, despite her armament, she was quite slow (3-4 knots at the most). Yet, she somehow manages to catch up with vessels like the Black Pearl and the Flying Dutchman, regarded to be the fastest ones afloat.
From the very first movie, several people were claiming that Will Turner is the spitting image of his father Bootstrap Bill.
Orlando Bloom and Stellan Skarsgård looks nothing alike.
(at around 13 mins) When the pirates wait beneath the bath house, Ragetti is seen peering up through the floorboards at the pants-less Elizabeth Swann with his wooden eye. He would therefore not be able to see or appreciate the scenery above.
