The room in the morgue Bill visits to see Mandy’s body is located in wing C, room 114 (C-Rm114, or CRM-114). CRM-114 was the name of the radio equipment in Kubrick’s film Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb and the serum given to Alex in A Clockwork Orange.
Harvey Keitel and Jennifer Jason Leigh were set to play Victor Ziegler and Marion Nathanson. They shot several scenes, but both stars had scheduling conflicts and left the film. Sydney Pollack and Marie Richardson took over the roles. Other stars reportedly up for Victor: Woody Allen (Kubrick was a fan). And, brace yourself, Steve Martin was being considered for the part of Bill.
Cruise hated his character: “‘I didn’t like playing Dr. Bill. I didn’t like him. It was unpleasant,’ admitted Cruise a year later in the only public criticism he’s ever given. ‘But I would have absolutely kicked myself if I hadn’t done this.'”
The Harfords’ New York City apartment resembled the one Kubrick and his wife, Christiane, lived in during the 1960s. Tom Cruise stated: “The apartment in the movie was the New York apartment he and his wife Christiane lived in. He recreated it. The furniture in the house was furniture from their own home. Of course the paintings were Christiane’s paintings. It was as personal a story as he’s ever done.”
Cruise and Kidman lived like their characters when the cameras weren’t rolling. “The couple slept in their characters’ bedroom, chose the colors of the curtains, strewed their clothes on the floor, and even left pocket change on the bedside table just as Cruise did at home,” writer Amy Nicholson revealed. Kubrick even discussed the couple’s real-life marital anxieties in private conversations so the actors could tap into their emotions while filming.
