Factual error: When Beeks is locked in the cage with the gorilla, it reacts in an overtly aggressive and sexual manner. First, gorillas are shy and gentle creatures. The male gorilla would be scared of him, not the other way around. Second, gorillas identify each other by their smell, and the smell of a female in heat is very specific. Beeks would smell like a horsehair rug and the male gorilla wouldn't be the slightest bit interested.
Factual error: The movie was set in the mid-to-late 1940s, however, the red wagons shown in the display in Higbee's corner window at the beginning of the film, bear a Radio Flyer script logo which was designed in 1967. (00:03:10)
