Question: Why was Will starting to become a "fish person"? Davy Jones and his crew only turned into "fishes" because he neglected his duties. If Will is still undertaking his duties then he shouldn't start having growths such as the algae and the starfish (seen when Henry summons the Dutchman at the start of the film).
Question: At the very beginning of the film, young Henry boards the Flying Dutchman to speak to Will. When Will looks behind him, he sees the shadows of several crew member starting to make their way towards him and he suddenly gets frightened that the crew will see Henry. Why would he react this way? Since he's captain of the Flying Dutchman, if his men saw Henry, Will could order them to leave Henry alone.
Question: What does the skeleton bar joke Jack's uncle says mean? Was it just supposed to be nonsense and not make sense?
Question: Why was Henry excited when he saw Carina's ankles?
Question: The breaking of the Trident cures all curses. So why is Davy Jones still cursed in the end credits?
Question: In the post-credits scene what was it under the bed?
Question: Why doesn't Barbossa use Blackbeard's sword to control his and Salazar's ship in battle? It isn't broken because he brings back the Pearl.
Question: Why would Henry become a sailor in the British Royal Navy knowing he would be abused and mistreated by the Navy?
Question: Can 12 horses really pull a huge building like that? Cause I know they put wheels on the thing in real life, so wouldn't that mean that the horses couldn't actually pull the building and so it was very fake?
Question: Jack's past was left very vague and inconsistent, in the film. Like who was the "last" pirate Captain who died and gave the compass to Jack, and why did he give it to Jack, he wasn't anybody special at the time? Salazar said he killed all the pirates, and Jack's ship was the last, how would that leave the world to be as it is, in the future, with all the pirate lords, and amounts of pirates still existing?
Question: Why did the bank people open the safe in the beginning of the movie? I get that they were trying to demonstrate the safety of the vault, but how does opening it do that? Feels like something written just to help the story move on.
Question: What was Jack's original plan for robbing the bank in the beginning of the movie? Cause when the safe gets stuck and the building starts moving he says "this was not part of the plan."
Question: Wasn't the crew of the Black Pearl trapped in the bottle? I'm just wondering how Marty got out or why he made no appearance in "On Stranger Tides"?
Question: If Barbossa claimed he left Carina at an orphanage for her to have a better life, why would he let her be arrested and sent to death for alleged witchcraft?
