When it comes to the spirituality and philiosophy, Pirates of the Caribbean: Dead Man's Chest seems to ask one major question (which the fact that it ask one question at all is fairly impressive since I don't think too highly of Jerry Bruckheimer films)
But the question that it asks is are we by nature pirates.
Or rather, are we good people who do bad things or bad people are capable of doing good. This question is definitly pondered in the Jack Sparrow (Johnny Depp) and Elizabeth Swann (Keira Knightley) characters.
Although the film ponders the idea, by the end it doesn't seem to offer any resolve to this thought, but allows for the possibility of both.
