What few people know is that some of Brooks' American films were also censored. The American Venus (1926) was criticized in Chicago because of "nudity." The City Gone Wild (1927) andKing of Gamblers (1937) were cut because of violence. God's Gift to Women (1931) was reproached because of its suggestive nature. During the 1920's and 1930's, some cities and states had their own censorship boards - and each ruled over the exhibition of motion pictures.
Some time ago, I came across a massive bibliography devoted to freedom of the press. This online bibliography, by Ralph E. McCoy, was published in 1967 and covered censorship of ideas in all forms - including books, newspapers, radio, television and film. I have gone through it and extracted (for my own reference) the many citations pertaining to film censorship in the United States during the teens, twenties and thirties. Here are a few articles and books that stand out:
