For more than three decades the Catholic Church through its Legion of Decency controlled the content of Hollywood films. Studios submitted their films to the Legion for a rating, which varied from general approval to condemnation. Documenting the inner workings of the Legion, The Catholic Crusade Against the Movies examines how the Church acquired such control and how the changes in the movie industry and American society at large in the post-World War II era eventually conspired against that institution's power and led to its demise.

In response to a series of sex scandals that rocked the movie industry in the early 1920s, the Production Code Administration and the Catholic Legion of Decency implemented a code stipulating that movies stress proper behavior, respect for government, and "Christian values." Based on an extensive survey of original studio records, censorship files, and the Catholic Legion of Decency archives (whose contents are published here for the first time), Hollywood Censored examines how hundreds of films were expurgated to promote a conservative political agenda during the 1930s. By taking an innovative view of how movies were made, and the conditions that made them, Hollywood Censored brings together such chapters as "Movies and Modern Literature," "Beer, Blood and Politics," and "Film Politics and Industry Policy" to form a rare look at America's most famous industry.
