Well it was Samuel Goldwyn that produced the film and Columbia released it. No MGM involved. The major problem was with the Gershwin Estate in they did not like the fact that an American Opera was turned into musical they also had problems with some of the casting decisions. The entire production was snake bite from the first. It was to be Goldwyn's last production, directors were changed, and the sets burned down adding to the cost. While it is not the American Classic that some people perceive it to be, it certainly is worth a Blu-ray just watch Sammy Davis Jr, Pearl Bailey, Dorothy Danbridge and the classic Sidney PortierDave B Ferris said:Also:The lion’s share of the criticism against Porgy and Bess originates from the late 1950s, when MGM turned Porgy and Bess into a major Hollywood picture. The film would introduce a much wider national audience to Porgy and Bess than the novel, play, or Broadway opera had reached; it would also premiere at a particular historical moment when a civil rights movement was just beginning to consolidate. Playwright Lorraine Hansberry, appearing on a Chicago talk show with Otto Preminger, the film’s director, articulated the most widely disseminated critique of Porgy and Bess. Hansberry insisted that the characters in Porgy and Bess were stereotypes which “constitute bad art” and result from an artist who “hasn’t tried hard enough to understand his characters.” Furthermore, the opera/film was rife with exoticism:“Over a period of time, [we] have apparently decided that within American life [there is] one great repository where we’re going to focus and imagine sensuality and exaggerated sexuality, all very removed and earthy things—and this great image is the American Negro.”When Preminger asked Hansberry if she thought the production ill-intentioned, Hansberry replied:“We cannot afford the luxuries of mistakes of other peoples. So it isn’t a matter of being hostile to you, but on the other hand it’s also a matter of never ceasing to try to get you to understand that your mistakes can be painful, even those which come from excellent intentions. We’ve had great wounds from great intentions.”http://www.courttheatre.org/m/article/the_porgy_and_bess_controversy/
