Nobody suffered on-screen the way Joan Crawford did, be it physically, mentally, or emotionally. She put herself through the ringer with poise and dedicated restraint, even as her later roles sold her to a new generation as a hysterical camp icon. While always maintaining her dignity and composure, she frequently used her expert knowledge of her strengths and how to effectively display emotion for the camera to play accomplished women having to fight for what they want in life. That's why she was so great in countless hectic thrillers, including Sudden Fear, where she played a woman in over her head in a deadly game of tainted love.
