At about 1:20 Alva smashes Mr. Johnson's glass during a toast in the bar, then later in the scene the glass is sitting on the table unbroken.
When Alva first gets onto the train to New Orleans, the woman sitting a couple of rows behind her is resting on her arm and seems to be sleeping. In the next closeup scene, she is awake and sitting up and awake.
Hazel implies she found out where Owen's apartment was from the picture postcard Alva sent to Willie. However, there is a closeup of Alva writing on the back of the card and she did not include any return address on it.
During the skinny-dipping scene, Alva is wearing a slip when she jumps into the water, despite the fact that she is bare-shouldered before and after she jumps in.
In one scene Willie watches a short freight train pass, reading out the names on the sides of the boxcars. Problem is the boxcars appear to be all-steel types. More consistent with the late 1960s or the present day (2021) but *not* consistent with the early 1930s when most would have been of wooden construction.
Willie is wearing Alva's red dress in the present day (beginning and end of movie), yet Alva was wearing it when she got on the train to New Orleans, and for the first few scenes after she arrived.
Near the end of the film there is a torrential thunderstorm when Alva leaves the apartment to meet Owen at his office for the walk home. When they arrive back at the apartment they are both soaking wet and discover Hazel has arrived while Alva was out. However, Hazel is not the least bit wet despite the fact that she must have been outside during the storm.
When Alva's train is headed to New Orleans, there is a shot of it crossing a long over-water trestle, and there is a modern highway bridge in the background.
The story takes place circa 1931-1932, but all of Natalie Wood's hair styles are strictly 1966.
Although the story is set in 1931-1932, automobiles visible in the background of the New Orleans sequence are of much later vintage.
This film is set in the early Depression era The wall calendar in the local railroad office shows the date as "Friday 14 August" but does not reveal the year. That particular date combination occurred in both 1931 and 1936. Williams' original story, most of the automobiles in the film, and many other aspects suggest 1931. However, in one sequence, the characters see the film "One Way Passage," which was not released until late 1932.
