When Dan Mathews exits his car in front of Carol Hayes's house, his suit jacket and pants are soaking wet from the rain. However, when he reaches her front door, his clothes appear to have completely dried.
After Mathews arrives at the barbershop, he and officer Harley check the lumber yard. Officer Harley wears his gun on his right side but carries it in his left hand and also shoots left handed. After the shootout, he does not use his holster but instead tucks his own gun into his belt. It appears the prop department did not have any left handed holsters for this actor to use.
Carol Hayes says the judge goes to the barbershop every Thursday for a haircut. The average person's hair grows 1/8th inch per week. It's unlikely anyone would get a haircut once a week.
When Carol pulls away after dropping off Red outside the barbershop, crew members are reflected in the side window of her car.
