Yeah, Alan Moore pretty much said he just takes the money and run when they make movies out of his books. The problem here was that the producer, Joel Silver, made an announcement that Moore saw the movie (or an early version) and he loved it, which totally pissed off Alan Moore. He then wanted a retraction of the statement, and when Silver refused, Moore demanded that they remove his name from the credits. Of course Moore went on and slammed Warner Bros., the company putting it out, also DC comic's parent company.... and you know about Alan Moore and DC Comics.
