Production
In 1936, a young San Francisco woman named Esther Eng (who would later become a well-known director) joined forces with a young actor Bruce Wong to try and tap into the Chinese movie-going market. Together, they managed to raise the money they'd need to get the film made, and then they set to work studying the taste of Chinese audiences. The film was shot in eight days in Los Angeles and San Francisco under Bruce Wong's Cathay Pictures production company. He cast his brother Beal in one of the lead roles.
