"Although this thirty-year period of American history is marked by widespread targeting of leftists in all areas of life, those in the film industry - predominately screenwriters - were considered to be in positions of great potential indoctrinating power, and found themselves under intense scrutiny as the cold war hysteria mounted. Ceplair and Englund trace the history of political struggle in Hollywood back to the formation of the Screen Writers Guild in 1933. Many of the blacklisted filmmakers were members of the Communist Party and all of the graylisted filmmakers had expressed their sympathy with progressive (mainly anti-fascist) causes."--BOOK JACKET.
