Question: When they're trying to escape the locker, Jack starts running on the deck of the ship whilst pretending to see something. Why didn't he just say "We need to roll the ship over, lets run from side to side to make it rock" instead of just leaving everybody guessing?
Question: If Davey Jones had already gone against his agreement to ferry souls to the afterlife, why couldn't he walk on shore more often too?
Question: Maybe I'm missing something, but why can't Elizabeth just live on Will's boat at the end? Someone suggested it was because she cannot go into Davy Jones' Locker, but she has been there and got out before so why not again? Also, Will's father isn't dead but he can travel with Will, so why couldn't Elizabeth just join his crew?
Question: Can anyone explain why Calypso caused the maelstrom to appear? Other than provide really cool visual effects for the movie, it didn't serve a purpose. I would have thought she'd do something against Davy Jones and/or his ship in particular for betraying her in the first place.
Question: When Davy Jones stabs Will, Jack looks absolutely devastated. Does he really care about Will, or is it because his plan didn't work, that he was considering becoming the new captain?
Question: Just after Jack's entrance, he yells at one of himselves for tying a knot badly and hallucination Jack says something to the effect of "Perhaps you could give us another chance?" and real Jack says "Shall I?" stabs hallucination Jack and says in his ear "That's exactly the sort of thinking that got us into this mess". What does he mean by this?
Question: How exactly was Will resurrected? Did that take place when the ship was able to rise back to the surface? And was the Flying Dutchman still a cursed ship at the end even though Will was resurrected and Bootstrap was back to normal human form. It seemed like it to me because one second Will is on the beach with Elizabeth and the next the ship is already on the horizon.
Question: After Jack's meeting with Beckett on board the Endeavour, they have a deal where Jack has to lead Beckett to the Pirates. Then why does Jack fire a canon on the main mast, making them incapable of pursuit? Later, however, he lets Will escape the brig, gives him the compass and lets him go to Beckett. The two actions seem inconsistent.
Question: Did Davey Jones corrupt his purpose? Is that why he turned out the way he did? His purpose was to ferry souls to the next world, was he not properly doing that?
Question: Why did the lady Calipso blow up into crabs?
Question: As the Black Pearl arrives at Shipwreck Cove, Tia Dalma and Barbossa have a very confusing conversation. Soon afterward, Barbossa has Tia Dalma sent to the 'brig.' Why would he need to lock her up, when everyone knows she wants to be freed from her human form? (01:29:30)
Question: After Jack and Barbossa see the corpse of the Kraken, Sao Feng's ship arrives next to the Pearl and so does Beckett's. During the scenes that follow, everyone double-crosses everyone else. It moves so fast, I just don't understand what exactly happens. Could someone please explain it to me?
Question: Beckett commands Davy Jones to kill the Kraken, and then when we see it, it doesn't appear to be missing any body parts. There's also nothing to suggest frenetic cannon shots. How did Jones kill the Kraken?
Question: How exactly did the dog escape from Pelagosto island?
