V For Vendetta creator Alan Moore is desperate to be disassociated from the screen adaptation of his classic comic strip - and is begging the producers not to credit him for his work. The cartoonist, who also conceived From Hell and The League Of Extraordinary Gentlemen, hates seeing his work diluted by movie-makers, and refuses to put his name to the result. He says, "I want them to say, 'We're not going to give you any money for your work, you're not going to get any credit for it and we're not going to put your name on it.' To see a line of dialogue or a character that I have poured that much emotional involvement into, to see them casually travestied and watered down and distorted... it's kind of painful. It's much better just to avoid them altogether."
Moore may be striking a blow for the integrity of his work, but the only way to ensure integrity is not to sell the rights to your work. Apparently Moore is willing to go that far, claiming he wants no profits from the movie.
Many writers complain that movies dillute their work, but true readers and moviegoers know that a movie cannot be a book and a book cannot be a movie. Personally, I see movies as advertising for books, Movies get people to buy books. Once they do, it's the author's job, same as always, to hook them with a good story.
