I bought this poster before I saw the movie because I was SO EXCITED for the adaptation of a book I loved so much.
They took my favorite Tom Clancy novel and ruined it. Any film that ends with the bad guy being impaled to death on something is a recipe for disaster (Sean Bean is impaled on an anchor, I think). While Sean Bean is wonderful, his character is less interesting than in the novel. The actor playing the balding bookstore owner isn't balding- you can see where he shaved a bald patch (which always looks phony). Also, since they could not put the real Prince Charles & Lady Diana in the movie (as they are in the novel), they had to substitute some anonymous royals, which lessens the dramatic impact.
