Prominent visitors to the set included architect Frank Lloyd Wright, who was the grandfather of actress Anne Baxter, and 20th Century Fox contract director Joseph L. Mankiewicz, who wanted to study the technique of Lubitsch during the early part of the filming when the latter was involved.
According to legend, Garbo agreed to star in the film after Bankhead had been signed. However, Garbo had been off the screen for 3 years, and Bankhead was considered "hot" after her performance in Hitchcock's "Lifeboat".
The script of this film was written and prepared under Ernst Lubitsch, and he was the original director of this film. He became ill during shooting, so Lubitsch hired Otto Preminger to complete the film.
In the Alfred Hitchcock/William Everson interview, it is revealed that Ernst Lubitsch did the storyboards for this film and handed them over to Otto Preminger to carry out the orders for Lubitsch.
According to Book "Ernst Lubitsch and Samson Raphaelson: A Study in Collaboration," Ernst Lubitsch directed the rehearsals of this film.
