Makes me feel like a true Star Wars nerd that I know most of these facts already haha.

The music? Supposedly Born Free (by John Barry) backwards (the story, a frustrated John Williams, working on the backside of the Born Free sheet music, became very inspired). And the pew pew noise is from a metal hammer hitting a cable (picture the kind that goes at angle from telephone pole to ground), and that wonderful engine noise is the sound of a helicopter, backwards. And Industrial Light and Magic has made even more money than Star Wars has. For some real geek pleasure, go watch Princess Leia being kidnapped by Darth Vader on the NYC subway: http://improveverywhere.com/
