Given today's cancel culture, here's a look at how Hollywood, of all places, was America's first "woke" system. We look at more than 50 classic films such as Gone with the Wind, Casablanca, East of Eden, The Ten Commandments, Convention City, and Lawrence of Arabia through the eyes and blue pencils of the Production Code Administration, the industry's censors. What emerges is not a gaggle of prudes but a staff with deep knowledge and sensitivity despite their mission to cleanse. Here is a time capsule of American mores and Hollywood's excesses over nearly four decades that led to today's letter rating system. Between 1934 and 1968, no Hollywood studio could make a movie without the permission of and a seal of approval from the Production Code Administration. The Production Code was Hollywood's official censor. Screenplays, books, plays, costumes and even story ideas and songs had to be okayed by the Code before they could be filmed, and the Code monitored every stage of the production process to ensure compliance. The correspondence between the Code and the studios was confidential, and the memos within the Code office itself were even more so. Well, not any more. The Naughty Bits pores through those files to show how the censors did their job. What was the world prevented from seeing in some of the greatest movies ever made, including Stagecoach, Some Like It Hot, Psycho, and His Girl Friday? Here is the sometimes funny, sometimes outrageous, always riveting history of movie censorship on a nitty-gritty level.
