Within the first 10 minutes, Jack Sparrow, Will Turner, and Elizabeth Swann have been introduced, have interacted, and have come into conflict.
When Jack Sparrow is on the run after escaping execution, where does he hide? The sword shop belonging to the Turners, of course! Where else?
Then Barbossa shows up, and all hell breaks loose. And everyone interacts again.
Nicely done, writers. Of course, having lots of swordfighting always helps.
