At 31 minutes into the film, a man and woman are shown having sex. Both appear to be completely naked. Because of the camera angle and her body position, one only sees the woman's breasts/nipples and the side of her bare hip. The man is positioned so that one only sees his bare chest. There is no genital nudity.
At 40 minutes into the film, another woman appears to be completely naked but one sees only her beasts and a small portion of her bare pelvic area. It is implied that this woman is a prostitute in bed with a male client who is bare chested. There is no genital nudity.
Susan Blakely has two nude scenes. First, at 1:14 into the film, a man pull down her dress top. She is shown wearing a thin silk bra which shows her nipple pokies. Soon, she removes her bra, revealing her breasts for several seconds. Her second nude scene begins at 1:22 into the film and is much more graphic and long. She's lying completely naked next to fully clothed Ben Gazzara. Her butt is shown throughout the scene. When she gets off the bed, there is a surprisingly very clear shot of her labia as she spreads her legs. However, this is very fast so there is only a glimpse of her labia. After donning some clothes around her lower torso, she dances around topless. The entire scene is about two minutes long.
