Errores

At the dance, every girl from Mrs. Shackleford's academy, who are seen sitting in a chair, has her hair hanging over half of her face in a parody of the hair style of Veronica Lake, but when they are dancing, none of them is wearing her hair this way.

In the train station Susan swipes a light-colored balloon to help her in her disguise as a child under 12. Once she is seated on the train, the balloon is much darker. When she stands as the conductors are questioning her, the balloon is lighter, but when she sits down and the guy next to her pops the balloon, it is dark again.

When Pamela arrives at the stopped train, she is directed left to the train car in which Major Kirby has a compartment. However, when she returns to her car which hasn't moved, she approaches it from the right, the opposite direction of Kirby's train car.

(at around 37 mins and 1h 18 mins) The external view of the outside of Lucy Hill's house has a six-panel front entrance door with a large brass door knocker, but when they move to the inside of the house, that six-panel front entrance door is missing the large brass door knocker.

When Pamela drives up to the stopped train, from inside the train her paneled wagon looks clean, but from outside it is muddy.

The cadet left the switchboard to get a radio, and returned with a battery portable valve radio. Although quite expensive to buy and to operate, there was a very large market for battery portable valve radios, and they were very common throughout the valve era. Batteries were the only possible power supply, because valves with "heaters" used with AC mains power electricity appeared after the D.C. battery types. Texas Instruments in 1952 demonstrated their all-transistor AM radios, but their performance was well below that of equivalent battery tube models. In August 1953 a workable all-transistor radio was demonstrated at the Düsseldorf Radio Fair by the German firm Intermetall. If one had no knowledge of the existence of battery portable valve radios in 1942, they might mistakenly believe that the portable radio is a fake, because the portable transistor radio was not invented till 1952.

Susan arrives at New York City's Grand Central Terminal and attempts to buy a fare from a New York Central Railroad ticket clerk. When she eventually has a ticket and is on the train, the exterior view is of a Pennsylvania Railroad train pulled by streamlined steam locomotive. That train would have departed from New York's Pennsylvania Station.

When Major Kirby is explaining the birds and bees to Sue, he mentions how moths are drawn to the porch light, and she says that she has screens on her front porch. At the end, Susan is watching the moths run into the light on a porch that has no screens.
