TV review of a litany of Hollywood impropriety.

The Honorable Will H. Hays, President of the Motion Picture Producers & Distributors of America, speaks directly into the camera about the important new technology to enhance the motion picture going experience, namely Vitaphone which allows the synchronization of the picture on screen with sound. Its development is important if only because of the importance of the motion picture as the chief amusement to millions in the American public. It allows the inclusion of music directly into the motion picture, music which already plays an important role in the motion picture in the pre-Vitaphone era. However, it allows symphonic music to be incorporated, which many of the small hamlets across the country could not afford to provide in their own movie houses. Vitaphone was developed by the Western Electric and Bell Telephone Companies, and is also greatly attributed to the work of Warner Bros. Pictures.

Looks at the stereotype-breaking films of the period from 1929, when movies entered the sound era, until 1934 when the Hays Code virtually neutered film content. No longer portrayed as virgins or vamps, the liberated female of the pre-code films had dimensions. Good girls had lovers and babies and held down jobs, while the bad girls were cast in a sympathetic light. And they did it all without apology.

Before the G, PG and R ratings system there was the Production Code, and before that there was, well, nothing. This eye-opening documentary examines the rampant sexuality of early Hollywood through movie clips and reminiscences by stars of the era. Gloria Swanson, Mary Pickford, Marlene Dietrich and others relate tales of the artistic freedom that led to the draconian Production Code, which governed content from 1934 to 1968. Diane Lane narrates.

A look at the forces that shaped Pre-Code Hollywood and brought about the strict enforcement of the Hays Code in 1934.
