The entire movie is based on a young man's life changing inspiration over a book. That simply. He found a book, read it, became enspired, changed his life. Despite the fact that the movie is hilarious, and Jack Black is in it, the story of the movie itself is absofuckinglutley brilliant, I love watching it.
btw, the book mentioned in the movie (I temporarily forget the title) is it an actual book, does any one know?
