I have DOUBT, the play, on my TBR list. Per reviews I've read, people who read the book/play were disappointed in the film. But I love Meryl Streep and didn't realize that Phillip Seymour Hoffman was in it, so with your recommendation, I'll watch it.
Speaking of Phillip Seymour Hoffman, I watched the movie CHARLIE WILSON'S WAR last night on HBO and loved it. Now I'll have to read the book by George Crile. In case I'm not the only one who's just now seen it, it's about a charmng, womanizing, boozing U.S. Congressman from Texas (played by Tom Hanks) who is a hero when his efforts to assist the Afghanistanis in their war against the Soviet Union are a huge success. How he does this is fascinating. Both Hanks and Hoffman were excellent.
As to 'W', I've never cared much for Oliver Stone's films and tend to ignore them. So I'll also skip this one on your recommendation, even tho' W was not one of my favorite presidents, to say the least.
