I know about that book. This idiot from a rich family who knew nothing about survival in the wild walked into Alaska and died there. He starved and eventually exposure to the elements when weakened by hunger killed him. What a moron.
edit: When they eventually found his body, they found the diary that he had kept about his life out there. I'm not sure that I approve of someone making money out of his tragic stupidity.
re-edit: And I KNOW that I don't approve of a movie being made about the poor guy. It's hard enough on his family that he's dead.
