The Last Night of the Barbary Coast
The Last Night of the Barbary Coast was an early example of the exploitation film, showing what was purported to be the last night of the Barbary Coast red-light section of San Francisco. In reality, the Barbary Coast wasn't shut down until 1917.
The film, directed by Hal Mohr and Sol Lesser, is now considered a lost film. Mohr, later an Academy Award winner, did the cinematography, and Lesser went on to become a Hollywood producer.
