 Producer William Fox (I) (qv) wanted Cooper, Miriam (qv) to play  in the film, as she so closely resembled the woman she was to  portray. According to Cooper, people on the street would mistake her  for Bianca De Saulles. Cooper fell ill when the film was to go into  production, bowed out, and was replaced by another actress, who  proved to be so terrible that Fox laid down the law with Cooper,  telling her to make the film no matter how sick or how well she  felt. It also helped that the director was Walsh, Raoul (qv), her  husband.
