Chuck Barris, Ivy league hitman

I had heard about Confessions of a Dangerous Mind for a long time as being a must read. When word that George Clooney was making his directorial debut on the work, my interest in it was piqued. I searched for it for a couple of months to no avail. When I searched for it online, I discovered that since it was out of print (and because of the movie buzz) that there were copies to be had - for over $100! I believe that I even saw one copy going for over $200. So, I did what any right thinking person would do and got it from the library (although that actually took a couple of weeks since my library had to borrow it from another). Well, it was worth the effort, and it has me eagerly anticipating the movie.
Has anyone seen any advance screenings of the movie?
