Violet is shown completely nude when lying on the sofa but when she sits up she is wearing panties.
While posing nude on the couch, Violet's hair covers much more of her in the close-ups than it does in the full length shots.
The brothel's ragtime pianist's hands (at the movie's beginning) are not coinciding with the music he is playing.
When Nell takes a customer upstairs to "view" Violet in the bathroom she tells him that she is a virgin.pure as the driven snow. Violet had already lost her virginity in an earlier scene. This may have been a deliberate lie but the customer would have soon found out.
In one scene, Violet holds a plastic doll as opposed to a composite one. Plastic dolls weren't available until the late 1940s.
In the final scene at the railroad station, Alfred Fuller Don Hood takes a photograph of Violet Brooke Shields with a Kodak No. 2 Portrait Brownie Camera, first manufactured April 1929.
Violet, distraught and crying, approaches a door and repeatedly bangs on it. No sound other than Violet weeping (itself obviously dubbed) can be heard.
After Violet stands up from trying to have her nude picture taken a man can be seen in the reflective part of the camera.
From 86:29 until 88:45 minutes, photographer Bellocq has posed the fully naked Violet on the couch, and she has no armpit hair and no pubic hair. Later Violet is seen walking around the room, however when Violet exits from the room, she is seen wearing a very thin g-string thong (skin colored, but the two rear straps are very visible).
When Bellocq is posing Hattie on the chaise lounge, the boom mic dips into the screen above them.
