I know that it was a book, and I also know that Denzel Washington played in the 2009 movie version. My question is, what did you think of the book and the movie? I'm also fairly certain that the movie was originally done in 1974, and the main character was Walter Matthau. Did anyone see that version? If so, what did you think of it compared to the 2009 film: better, worse, or about the same?
