In 1958 New York Diane Arbus is a housewife and mother who works as an assistant to her husband, a photographer employed by her wealthy parents. Respectable though her life is, she cannot help but feel uncomfortable in her privileged world. One night, a new neighbor catches Diane's eye, and the enigmatic man inspires her to set forth on the path to discovering her own artistry.
At 1:27:55, Diane (Nicole Kidman) kisses her husband who is lying on the bed, silently telling him what she's going to do, which is to fuck the overly-hairy guy living upstairs. Her husband catches her and the guy almost about to kiss earlier (1:28:46) so he knows what's up and they have already talked about it. He doesn't stop her as she leaves their unit to go to the guy's place upstairs.
Inside the guy's place, he asks her to shave all the hair and fur on his face and body. After she's done doing so, revealing to us that it's Robert Downey, Jr. who is playing the guy behind all the fur, she makes love to him (1:34:50). We see her naked butt and side boob.
