INFO:

The silent film era came to an end in 1929. In 1930, the Motion Picture Association of America drew up the Motion Picture Production Code, also known as the Hays Code, to raise the moral standards of films by directly restricting the materials which the major film studios could include in their films. The code authorized nudity only in naturist quasi-documentary films and in foreign films. However, the code was not enforced until 1934.
