Plot Hole Answer?

Rating: 10/10 (22 April 2005)

Why do the pirates of the Black Pearl need Will Turner's blood to lift the curse? Easy peezy and this is (not clearly) explained in the film. Because Will's farther, Boot Strap Bill, was sent to Davey Joan's Locker, after the treasure was taken from the casket, therefore he could not appease the cure for the treasure he stole. Therefore, the blood of his siblings must be used to represent him as the pirates return the gold to the casket and appease the curse. Hope that helps in explaining the plot hole, well, that's how I and my mates saw it.
This is one of those rare films I can watch again and again and again, because it is so entertaining! I love a good swash and buckle like the rest of em' and this is one of the best!
