When Kim Novak was filming the fall into the water, Hitchcock found that it was fun to jump into the water again and again for Cape Kim Novak. In fact, this shot has reached Hitchcock's standards, but he insisted on making Kim Novak take many shots for fun.
At the end of filming, the film’s screenwriter Sam Taylor proposed to add Novak’s subjective point of view flashback, but Hitchcock has deleted the play from all copies. In the end, the co-producer and distributor Paramount overturned Hitchcock's decision. Hitchcock was ordered to add the scene back.
In order to adjust the lighting to the right position, Hitchcock spent a week shooting Marron staring at a portrait in the Palace of the Legion of Honor.
During the trial screening of the film, the producer, Paramount, discovered that Novak's review of the scenes would make the audience guess the answer to the story and lose interest in watching the movie. So, Herbert Coleman set out to retake a few more shots.
Kim Novak hated the gray outfit he wore in the film when the film began, because it made her feel very restrained. But as the shooting continued, she gradually adapted to this costume.
