Gary Cooper earned $129,000 for a couple of months in the studio shooting this movie.
After this film was released, Shirley Temple's fan mail reached five hundred letters a day.
In the scene in which Penny bursts into tears after finding the stolen necklace, Shirley Temple's tears were genuine. Just before filming the scene, Temple learned that her friend Dorothy Dell (her co-star in Little Miss Marker) had been killed in a car crash. Because of Temple's affection for Dell, the news was kept from her for as long as possible.
