I am also a fan of the movie, and after years I decided to read the book which he is suited. Obviously we find there most of what is found in the film, modulo some transformations ("transmogrifications" would say in English more accurately), and details and additional scenes that are truly as tasty as that we already knew.
Note, the author continued the Miles & Jack's adventures in "Vertical" and most recently in "Sideways 3: Chile".
