In 1917, Cooper and Walsh began work on a film based on the Blanca de Saulles trial. Cooper bore such a resemblance to De Saulles that Fox wanted to leave her name off the credits to insinuate De Saulles had played herself. Cooper refused. The film was also notable for featuring Peggy Hopkins Joyce as a courtesan, though she didn’t realize it until the film premiered. The film was controversial and received what amounted to an X rating for its time, as no children were allowed. The film is now considered a lost film.
