Should I sue over "State of Play?"

I just saw "State of Play," the suspense movie about the fictional moribund Washington Globe, like so many newspapers on life support, kept alive by a few dedicated reporters. Anyone know a good lawyer? Just kidding, but the parallels with "Philip's Code: No News is Good News - to a Killer" are difficult to ignore. Yes, I know I'd be in line behind the BBC. Nevertheless, I had the feeling as I watched the movie that someone behind the credits read my book.
In both, the reporter is personally involved. In the book, there's the death of the main character's son. In the movie, the reporter "shagged" a source's wife. Both get major breaks from the coroner's office, both deal with technological changes, and both use reporter's tricks to get information. I expected Russell Crowe to use lines from the book - "Truth is the sum of the Facts," "NEWS is the important part of newspaper" or "news is what the newspapers say it is." Not only that, there are main characters who are military vets who lost faith and hope.
And, of course, there are the surprise endings. I may be biased, but the book's is better.
