After murdering her husband, Marie undergoes a gradual mental deterioration, culminating in a collapse in the courtroom. Director Archie Mayo expected Davis to deliver a histrionic performance, but the actress, whose own sister suffered from a mental disorder, insisted a subtle portrayal of the breakdown was more appropriate and accurate. "When I firmly and sincerely believed I should play my role a certain way, I wasn't afraid to argue about it with my director", Davis remembered. "They wanted me to be a raving lunatic in the courtroom scene, pull my hair, and scream. That is the only way insanity had been played on the screen up to that time." After the film was completed, studio executives felt viewers would fail to realize Marie was insane and insisted Davis re-shoot the scene. She agreed she would do so only if preview audiences did not realize the character had descended into madness. "I was never asked to do a retake", Davis recalled.
