"If you thought you knew everything about Hillary Clinton, wait till you see the movie," said an ad last year for "Hillary: The Movie," a scorching attack on the woman then running for president.
Citizens United, the conservative group behind the film, promoted it as featuring 40 interviews - a "cast to end all casts"– and promised that if "you want to hear about the Clinton scandals of the past and present, you have it here! 'Hillary: The Movie' is the first and last word in what the Clintons want America to forget!"
Few Americans ever saw the ad; a federal court ruled that it broke the law on campaign advertising.
