In the closeup of Rachel's breasts, her hair lies over her left shoulder. When the camera shows her face and upper torso in the next shot, her hair is not over her shoulder.
Rachel refers to herself as "Amish". The word "Amish" is a term used by non-Amish; the Amish would refer to themselves as the "plain folk".
Stock footage shown in reverse. Shot from raised track after Rachel is first seen looking out train window in opening sequence shows old, B/W footage of people walking on street below. As train "approaches" the street corner below, a man can be seen walking backwards.
When the actors smoke, they use filtered cigarettes. Most cigarettes of the era were non-filtered. Filters did not become popular until after the 1950s.
The film was set in 1925, but in the opening montage, a stock shot of Times Square shows a marquee with "All Quiet in the Western Front", which opened in New York on April 29, 1930.
