The movie was the favorite of Italian director Bernardo Bertolucci's poet father. When the director came to visit New York City's Museum of Modern Art in the late 1960s, he asked their film department to screen their print of it for him so he could see it for himself.
Ray Milland actually got stuck in the tub while shooting the bathtub scene, according to director Mitchell Leisen. He kept the camera rolling and inserted the incident into the film.
