Alfred Hitchcock had chosen a very expensive robe for Grace Kelly to wear when she answered the phone. The actress balked and said that no woman would put a robe on to answer the phone when she was sleeping alone but would answer it in her slip. Hitchcock agreed to do it her way and liked the way the rushes turned out. The director agreed to allow the actress to make all costume decisions for herself in their subsequent films together.

Not only was ‘Veronica Lake’ pregnant during the making of this movie, she was between six and eight months pregnant. Production took place from June 12 to July 22 1941, and her daughter Elaine Detlie was born on August 21, 1941. The only other people involved in the production who knew of her condition were the costume designer, Edith Head, and Louise Sturges, wife of Preston. Miss Head designed costumes to hide the condition. Miss Lake was afraid that she would not be allowed to make the movie if her advanced state of pregnancy was revealed, owing to the physical demands of the role.

The famous scene in the Trevi Fountain was shot in March, when nights were still cold. According to Federico Fellini, Anita Ekberg stood in the cold water in her dress for hours without any trouble.

Still freezing, he downed an entire bottle of vodka, so that he was completely drunk while shooting the scene.
