Anachronisms: The story takes place in 1936, but a US 50-star flag is featured at the racetrack. This should have been a 48-star flag.
Anachronisms: Todd Jackson's car is either a 1940 or 1941 Plymouth
Anachronisms: The car from the French Consulate is a 1946 Dodge.
Revealing mistakes: When Katya is having her hair combed, a fly lands on her forehead - and then jumps onto the camera lens.
Anachronisms: The uniforms that the Japanese soldiers wear is inaccurate, given that the movie takes place in the years 1936-1937. The Japanese Army did not wear their rank insignia on their collars until May 1938; until then rank was displayed on the shoulder. Also, their shade was a bit darker khaki than what is depicted in the movie.
Anachronisms: The Japanese flag should have the chrysanthemum design instead of the rising sun design.
Anachronisms: A song performed in a night club early in the movie is the original Cninese (Mandarin) version of what became an international hit for Frankie Laine in the early 50s under the name of "Rose Rose I Love You". The original was written in 1940, while the scene was set in 1937.
