Finding out how your favorite movies came to be is generally very rewarding and educational. You seek out The Seven Samurai, and thank the film gods that a robotic shark failed to work. At the very least, you can win trivia contests by knowing what Rosebud was, and impress your friends by telling them who was originally cast as Aragorn.
And then there's the stuff you wish you had never known. This week, you may have been one of the Indy fans who eagerly downloaded the Raiders of the Lost Ark transcript, where George Lucas, Steven Spielberg and Lawrence Kasdan hashed out ideas for one of the greatest film characters of all time. Cool stuff. Useful if you aim to write books or movies someday. Then I read this bit about Marion and Indy, and their ideas for their early love affair gone wrong:
GL: I was thinking that this old guy could have been his mentor. He could have known this little girl when she was just a kid. Had an affair with her when she was eleven.
LK: And he was forty-two.
GL: He hasn't seen her in twelve years. Now she's twenty-two. It's a real strange relationship.
SS: She had better be older than twenty-two.
