The scene where Don Ameche and Vivian Blaine are sharing a bed must have come close to challenging the censors. It must have barely passed their scrutiny even though the actors were unaware that they were sharing a bed at the start of the scene.
Yes, I wondered about that scene too. It was very rare at that time to see a man and a woman together on a double bed. I thought the general rule was that one of them had to have both feet on the floor if they were photographed on a bed together! Perhaps it was allowed because Ameche was lying on top of the covers and Vivian Blaine was underneath them? "Where does imagination end and reality begin?" (Night Of The Demon 1957)
