Elizabeth’s (Keira Knightley) freedom is being removed from the constraints of society, including marrying the lowly blacksmith William Turner (Orlando Bloom). She wants to make her own decisions, not be limited by her station in society.
Will’s freedoms also lies with Elizabeth. However, he also desires respect and recognition as a blacksmith. He makes the swords, but the credit lies with his master/teacher. Therefore, freedom for Will is being independent as a skilled creator, not just relying on his mentor.
The pirates of the Black Pearl want to be free of their curse from Cortez’s gold. After spilling “the blood of William Turner”, they will be living which means they can eat, drink, and be marry once again.
Even death in the end is a sort of freedom. Jack is released from his grudge against Barbossa (Geoffrey Rush) by shooting him after the curse lifts. Captain Barbossa is released from death on earth to death in the afterlife.
Everyone has something confining them. Finding the freedom we has humans seek can lead us to what we want, or something entirely new.
Freedom is not the only theme present in this movie. Consider what else is going on.
