Coincidence?

I recently read a thing on AOL calling Pirates of the Carribean "The new Star Wars". At first, I was skeptical, but the similarities are striking! For example, they compared Han Solo to Jack Sparrow. Both are always looking out for themselves, and both owe debts to ugly chracters (jabba the hutt, davy jones). Luke Skywalker and Will Turner both want to do the right thing, and both don't know their father until the second film. They then save their fathers, and both duel their fathers. Hmm. And of course both trios of characters have a royal female, Princess Leia and Elizabeth, the governer's daughter and pirate king in the third one. And, to top it off, both third films started with a rescue of the Jack Sparrow/Han Solo character from Davy Jones/Jabba the Hutt. Weird wild stuff.
