Background: The Man with the Golden Arm is a 1955 American drama film with elements of film noir, based on the novel of the same name by Nelson Algren, which tells the story of a drug addict who gets clean while in prison, but struggles to stay that way in the outside world. Although the addictive drug is never identified in the film, according to the American Film Institute "most contemporary and modern sources assume that it is heroin", in contrast to Algren's book which named the drug as morphine. The film stars Frank Sinatra, Eleanor Parker, Kim Novak, Arnold Stang and Darren McGavin. It was adapted for the screen by Walter Newman, Lewis Meltzer and Ben Hecht (uncredited), and directed by Otto Preminger.
Context: Preminger decided to release the finished film prior to submitting it for a Code seal of approval. He contended that his film would not entice any viewers to take drugs, since drug use was depicted as having severely negative consequences. The black-and-white film was also the first to portray heroin use as a serious literary topic, rejecting the standard "dope fiend" approach of the time. United Artists, which had invested $1 million in the film's production, opted to distribute the film, even though doing so could result in the company being fined $25,000 by the Motion Picture Association of America (MPAA). The president of United Artists, Arthur Krim, expressed the company's hope that the PCA would make an exception to its usual rules and grant the film approval because of the film's "immense potential for public service." The film received several advance bookings in November and early December 1955, before the PCA had made a decision on whether to grant a Code seal.  However, in early December 1955, the PCA denied the film a Code seal, and the decision was upheld upon appeal to the MPAA. As a result, United Artists resigned from the MPAA that same month (although the company re-joined a few years later). The National Legion of Decency also showed disagreement with the PCA ruling by rating the film as a "B" meaning "morally objectionable in part for all", instead of a "C" meaning "condemned", which was the rating normally given to films that were denied a Code seal. Large theater circuits including Loews also refused to ban the film and instead showed it despite the lack of a Code seal. As a result of the controversy, the MPAA investigated and revised production codes, allowing later movies more freedom to deeply explore hitherto taboo subjects such as drug abuse, kidnapping, miscegenation, abortion, and prostitution.  In the end, The Man With The Golden Arm finally received the Production Code seal number 17011 in June 1961, which permitted the film to be reissued and sold for television broadcast.
Question: what were the controversies?
Answer: the PCA denied the film a Code seal,

Problem: Background: Curtis Mayfield was born on June 3, 1942 in Chicago, Illinois, the son of Marion Washington and Kenneth Mayfield, one of five children. Mayfield's father left the family when Curtis was five; his mother (and maternal grandmother) moved the family into several Chicago public housing projects before settling in Cabrini-Green during his teen years. Mayfield attended Wells Community Academy High School before dropping out his sophomore year. His mother taught him piano and, along with his grandmother, encouraged him to enjoy gospel music.
Context: Curtis Mayfield was known for introducing social consciousness into African-American music. Having been raised in the Cabrini-Green projects of Chicago, he witnessed many of the tragedies of the urban ghetto first hand, and was quoted saying "With everything I saw on the streets as a young black kid, it wasn't hard during the later fifties and sixties for me to write my heartfelt way of how I visualized things, how I thought things ought to be."  Following the passing of the Civil Rights Act of 1964, his group the Impressions produced music that became the soundtrack to a summer of revolution. It is even said that "Keep On Pushing" became the number one sing along during the Freedom Rides. Black students sang their songs as they marched to jail or protested outside their universities, while King often used "Keep On Pushing", "People Get Ready" and "We're A Winner" because of their ability to motivate and inspire marchers. Mayfield had quickly become a civil rights hero with his ability to inspire hope and courage.  Mayfield was unique in his ability to fuse relevant social commentary with melodies and lyrics that instilled a hopefulness for a better future in his listeners. He wrote and recorded the soundtrack to the 1972 blaxploitation film Super Fly with the help of producer Johnny Pate. The soundtrack for Super Fly is regarded as an all-time great body of work that captured the essence of life in the ghetto while criticizing the tendency of young people to glorify the "glamorous" lifestyles of drug dealers and pimps, and illuminating the dark realities of drugs, addiction, and exploitation. His work influenced many, and it is said that Mayfield truly introduced a new style of black music.  Mayfield, along with several other soul and funk musicians, spread messages of hope in the face of oppression, pride in being a member of the black race and gave courage to a generation of people who were demanding their human rights, without abandoning the struggle for equality. He has been compared to Martin Luther King, Jr. for making a lasting impact in the civil rights struggle with his inspirational music. By the end of the decade Mayfield was a pioneering voice in the black pride movement, along with James Brown and Sly Stone. Paving the way for a future generation of rebel thinkers, Mayfield paid the price, artistically and commercially, for his politically charged music. Mayfield's "Keep On Pushing" was actually banned from several radio stations when riots began flaring up in some cities. Regardless of the persistent radio bans and loss of revenue, he continued his quest for equality right until his death. His lyrics on racial injustice, poverty and drugs became the poetry of a generation.  Mayfield was also a descriptive social commentator. As the influx of drugs ravaged through black America in the late 1960s and 1970s his bittersweet descriptions of the ghetto would serve as warnings to the impressionable. "Freddie's Dead" is a graphic tale of street life, while "Pusherman" revealed the role of drug dealers in the urban ghettos.
