Book excerpt: For more than three decades the Catholic church, through its Legion of Decency, had the power to control the content of Hollywood films. From the mid-1930s to the late 1960s the Catholic Legion served as a moral guardian for the American public. Hollywood studios submitted their films to the Legion for a rating, which varied from general approval to condemnation. This book details how a religious organisation got control of Hollywood, and how films like A Streetcar Named Desire, Lolita, and Tea and Sympathy were altered by the Legion to make them morally acceptable. Documenting the inner workings of the Legion, The Catholic Crusade against the Movies also examines how the changes in the movie industry, and American society at large in the post-World War II era, eventually conspired against the Legion's power and so lead to its demise.
