Although he was draft-exempt due to a physical injury, actor William Lundigan enlisted into the Marines out of patriotism and served in Okinawa during WWII. Under contract to MGM at the time he enlisted, boss Louis B. Mayer was furious with him for enlisting just as the studio was promoting him as a star and he was dropped.In 1963 and 1964, William Lundigan joined fellow actors Walter Brennan, Chill Wills, and Efrem Zimbalist, Jr., in making appearances on behalf of U.S. Senator Barry M. Goldwater, the Republican nominee in the campaign against U.S. President Lyndon B. Johnson.

In 1947, Adolf Menjou cooperated with the House Committee on Un-American Activities in its hunt for Communists in Hollywood. Menjou was a leading member of the Motion Picture Alliance for the Preservation of American Ideals, a group formed to oppose Communist influence in Hollywood. Other members included John Wayne, Barbara Stanwyck (with whom he co-starred in Forbidden in 1932 and Golden Boy in 1939) and her husband, actor Robert Taylor.
Because of his political sympathies, Menjou came into conflict with liberal actress Katharine Hepburn. Menjou appeared with her in the films Stage Door and State of the Union, which also starred Spencer Tracy. Hepburn was strongly opposed to Americans co-operating with the McCarthy hearings. It was reported by William Mann in his biography of Hepburn, Kate, that during the filming of State of the Union, she and Menjou only spoke to each other when required to in the film script.

In the 1940s, Charles Coburn served as vice-president of the Motion Picture Alliance for the Preservation of American Ideals, a conservative group opposed to the Communist infiltration and proselytization in Hollywood during the Cold War.
The Hollywood blacklist was made up of anyone within the entertainment industry who supported the Communist Party and it resulted in many actors, writers and directors being forced out of their jobs. Other Hollywood supporters of the blacklist included Ronald Reagan, John Wayne, Hedda Hopper, Adolphe Menjou, Ward Bond, Robert Taylor, and Ginger Rogers.
Shortly before his death in 1961, Coburn joined the Citizens Councils of America, an organization opposed to the desegration of public schools brought about by the 1954 Supreme Court ruling on Brown v. Board of Education.
