That is still over 30.00 an hour and your making a MOVIE with SCORSESE! Really you wouldn't!? I know plenty of people who would do it for free (like me)! It is sad that such a unique experience, to be on the set of one of the best directors of all time, was wasted on someone who did not appreciate it.
As far as the book goes, it is not just a little different but completely different from the movie. I read it last year and just loved it. I think Tevis is a great writer and really captured the inner struggle of a aging legend.
To me, the absence of the Fats character in the movie, was far less surprising than the complete absence of the Tom Cruise character in the book. From what I read, the original script was much closer to the book, but Newman really wanted a character like the George C Scott of the Hustler and requested a rewrite.
I have mentioned this before but if you enjoy his two pool books, he also wrote a brilliant book about a female chess prodigy, called The Queen's Gambit, it is excellent!
