So, a friend of mine has been an extra in the pirates of the caribbean III.  Talk about lucky!  He got to live in the Bahamas for 6 weeks, then go home to Florida for a while, and then he got to go out to L.A. for over 2 months.  He got to be trained as a British soldier, and then don pirate clothes for a scene where he stood right next to Kiera Knightly.  The only thing that would really stink is that he lived in a hotel room with like 5 guys in it for the entire time he was in L.A. to save on dollars.  And, he had to wait in the cold water for hours at a time while they would reshoot scenes.  He went out and purchased a wet suit after one day of that!
