Heres my take on things
most likly hung but to keep a PG13 rating it was not shown since there would be no reprive for them
What happened to the treasure Jack made off with from the cave? One minute he's rowing back to the Dauntless with Will and Liz, draped in gold. Next scene he's on the gallows. Did he give it to Will so he could become a gentleman pirate?
most likly the British goverment got it since the govener was onboard the ship when Jack was arrested
How did Jack get cursed if he wasn’t with the crew when they took the cursed treasure? They marooned him on the way to the island, right?
already been covered to my satisfaction
How did Jack come to learn of Isla De Muerta? And if he knew he was cursed, why wouldn't he be magically drawn to the gold just like the Black Pearl crew? Or is that why he showed up in Port Royal in the first place?
some one else showed him first then he got/made the compass that pointed the way there or he was just that good and was navigate in his head only and used the compass as a prop that only he knew how to use
How could he get drunk on rum if he was cursed? It was made pretty clear that all they could do was sail the sea tracking down the gold....
this has been covered
Where are the other inhabitants of the Caribbean? Spanish? French?
hidding from the Black Pearl
If they can’t die, and Bootstrap Bill was cursed too, shouldn't he be sitting at the bottom of the sea somewhere chained to a cannonball, bored as hell? Course soon as the curse is lifted, he'd drown I guess....
well he was a pirate and was most likely cursed as well
but he had what 10 to 15 years to drag or break free of the cannonball
My guess is that he'll show up in the sequel maybe missing a hand or foot
Port Royal is supposed to be "the wickedest city on earth"…where is everyone?
already covered
How could Jack sail a brig with just Will who’s all lubber?
Jack is just that good
look at when we first see him sailing into Port Royal he bails what 3 buckets of water and that is just enough so that he can step off the mainmast as comes to port the first time and not get his feet wet
