20 Things You Didn't Know About Eyes Wide Shut
17. Kidman And Cruise Were Intentionally Kept Apart
To create the illusion of a marriage in conflict, Cruise and Kidman, married in reality, would be subjected to an extraordinary regime, including an enforced secrecy between the couple, who would normally share notes when working together.
In this case, Kubrick maintained that they share NOTHING with each other, especially the sequence in which Kidman's Alice recounts her sexual fantasies of a naval officer, much to her husband's distress.
During the six day shoot, Kidman was forbidden to discuss anything that went on, thus intentionally creating a degree of mistrust between the two, something which Kubrick believed would spill out into their performance in the film.
