Best romance movie mistakes of 1963
Continuity mistake: The train is stopped because Spectre has pushed a 1950's style Dodge truck full of flowers in the trains path. Later, when James is driving it trying to avoid the grenades dropped from a helicopter, the truck has turned into a very different looking 1961 Chevrolet truck.
Character mistake: On the day Rebecca arrives home, Junior Douglas says that he was "Valedictorian, Class of '95." Earlier, Drago talked of almost killing Running Buffalo "during that trouble back in the '40's," which would have been about 50 years earlier. That would mean Drago and McLintock were fighting Indians when they were babies, or possibly before they were born!
Factual error: Luki shows up late at night to retrieve his baseball cap from the house where Amelia is staying. He explains that the hat is very important to him because it was signed and given to him personally by Stan Musial. Stan Musial played his whole career for the Cardinals, but the cap is a Boston Red Sox cap.
