On 12th February 1945, Albert Maltz wrote an article for the New Masses calling for more intellectual freedom in the Communist Party. "It has been my conclusion for some time that much of the left-wing artistic activity - both creative and critical - has been restricted, narrowed, tuned away from life, sometimes made sterile - because the atmosphere and thinking of the literary left-wing had been based upon a shallow approach... I have come to believe that the accepted understanding of art as a weapon is not a useful guide, but a straitjacket. I have felt this in my own works and viewed it in the works or others. In order to write at all, it has long since become necessary for me repudiate it and abandon it."

Maltz went on to argue that it was wrong to judge creative works primarily by their ideology. He used the example of how a communist journal in 1940 attacking a play by Lillian Hellman, because its anti-Nazi politics were anathema during the period of the Nazi-Soviet Pact.

Victor Jerome, the head of the Party's Cultural Commission, organized the attack on Maltz. In the next edition of the New Masses, the novelist, Howard Fast, claimed: "He advocates, for the artist, retreat. He pleads with him to get out of the arena of life. The fact that life shows, and has shown for a generation now, that such retreat is tantamount to artistic death and personal degradation, cuts no ice with Maltz." Joseph North wrote that Maltz would chop down "the fruitful tree of Marxism" to cure some weak branches.

Alvah Bessie was another who criticised Maltz and suggested that what he said went against Marxism. "He (Maltz) nowhere states his frame of reference or identifies the point of departure from which he launches what is, objectively, not only an attack on Marxism but a defense of practically every renegade writer of recent years who ever flirted with the working-class movement... We need Party artists. We need artists deeply rooted in the working class."

Other members such as Michael Gold, John Howard Lawson and William Z. Foster joined in. "Maltz, they insisted, had been taking dangerous liberties with the supremacy of political commitments over artistic tastes." (24) Lawson pointed out: "We cannot divorce the views expressed by Maltz from the historical moment he selects for the presentation of these views. He writes at a time of decisive struggle. The democratic victories achieved in the Second World War are threatened by the still powerful forces of imperialism and reaction, which are especially strong in the United States."

Victor Jerome forced Maltz to write a retraction of his first article. On 9th April, 1946, two months after his initial effort, Albert Maltz published a second article in the New Masses: "I consider now that my article - by what I have come to agree was a one-sided, non-dialectical treatment of complex issues - could not... contribute to the development of left-wing criticism and creative writing."

I. F. Stone later recalled he was appalled by the way Maltz was treated: "He (Jerome) is a hell of a nice guy personally but politically he has tried to ride hard on the intellectuals in a way most offensive to anyone who believes in intellectual and cultural freedom... often in most humiliating ways - as in the belly-crawl forced... on Albert Maltz... He (Jerome) has a dictatorial mentality."

After the Second World War the House of Un-American Activities Committee began an investigation into the Hollywood Motion Picture Industry. In September 1947, the HUAC interviewed 41 people who were working in Hollywood. These people attended voluntarily and became known as "friendly witnesses". During their interviews they named several people who they accused of holding left-wing views.

Maltz appeared before the HUAC on 28th October, 1947, but like Alvah Bessie, Herbert Biberman, John Howard Lawson, Adrian Scott, Dalton Trumbo, Lester Cole, Edward Dmytryk, Samuel Ornitz and Ring Lardner Jr, refused to answer any questions. Known as the Hollywood Ten, they claimed that the 1st Amendment of the United States Constitution gave them the right to do this. The House of Un-American Activities Committee and the courts during appeals disagreed and all were found guilty of contempt of Congress and Maltz was sentenced to twelve months in Ashland Prison and fined $1,000.

Blacklisted by the Hollywood studios, Maltz worked without credit on several movies such as The Robe (1953) and Short Cut to Hell (1957). He went to live in Mexico during this period. Howard Fast later described a visit he made to Maltz's home: "He had taken a small house in the San Angel neighborhood and had installed his family there... Prison had had a much deeper and more destructive effect on Albert than me. He was a very sensitive person... I had a great affection for him, and it broke my heart to see his resignation and misery."

In 1959 Frank Sinatra announced that he proposed to break the blacklist by employing Albert Maltz as the screenwriter of his proposed film, The Execution of Private Slovik, based on the book by William Bradford Huie. Sinatra soon came under attack for his decision. He nearly came to blows with John Wayne, who called him a "Commie" when they met in the street. However, what really hurt Sinatra was the criticism he received in the press. This included claims that his friend, John F. Kennedy, also wanted an end to the blacklist. Sinatra issued a statement to the press: "I would like to comment on the attacks from certain quarters on Senator John Kennedy by connecting him with my decision on employing a screenwriter. This type of partisan politics is hitting below the belt... I make movies. I do not ask the advice of Senator Kennedy on whom I should hire. Senator Kennedy does not ask me how he should vote in the Senate."

Michael Freedland, the author of Witch-Hunt in Hollywood (2009) argues that "Kennedy didn't like the association with the name of one of the Hollywood Ten. He would soon run from President and he was worried that he could harm him." A few days later Sinatra took out another paid-for advertisement in the newspapers: "In view of the reaction of my family, friends and the American public I've instructed my lawyers to make a settlement with Albert Maltz. My conversations with Maltz indicate that he has an affirmative, pro-American approach to the story, but the American public has indicated it feels that the morality of hiring Maltz is the most crucial matter and I will accept this majority opinion."

When the blacklist was lifted Maltz wrote The Pistolero of Red River (1967) and Two Mules for Sister Sara (1970). Maltz reacted angrily when Dalton Trumbo argued in 1970 that all screenwriters were victims during McCarthyism. "Some suffered less than others, some grew and some diminished, but in the final tally we were all victims because almost without exception each of us felt compelled to say things he did not want to say, to do things that he did not want to do, to deliver and receive wounds he truly did not want to exchange. That is why none of us - right, left, or centre - emerged from that long nightmare without sin."

In an interview he gave to the New York Times in 1972 he compared the experiences of Adrian Scott and Edward Dmytryk: "There is currently in vogue a thesis pronounced by Dalton Trumbo which declares that everyone during the years of blacklist was equally a victim. This is factual nonsense and represents a bewildering moral position.... Adrian Scott was the producer of the notable film Crossfire in 1947 and Edward Dmytryk was its director. Crossfire won wide critical acclaim, many awards and commercial success. Both of these men refused to co-operate with the HCUA. Both were held in contempt of the HCUA and went to jail. When Dmytryk emerged from his prison term he did so with a new set of principles. He suddenly saw the heavenly light, testified as a friend of the HCUA, praised its purposes and practices and denounced all who opposed it. Dmytryk immediately found work as a director, and has worked all down the years since. Adrian Scott, who came out of prison with his principles intact, could not produce a film for a studio again until 1970. He was blacklisted for 21 years. To assert that he and Dmytryk were equally victims is beyond my comprehension."

Albert Maltz, who also wrote The Beguiled (1971), Hangup (1973) and Scalawag (1973), died in Los Angeles on 26th April, 1985.
