When the car stops with a busted water pump, there is a scene where they get back in the car. There is no steam in this scene. The shots before and after contain steaming.
In the film, Floyd gets his nickname when he is in a brothel. This is false. In reality, after one of his bank robberies, a payroll master described Floyd as "a mere boy - a pretty boy with apple cheeks."
In the film's motel scene just before the robbery of the Hayes City Bank, an agent yells out "Floyd - FBI!". At that time, the agency was known as the Bureau of Investigation (BOI). Charles Arthur "Pretty Boy" Floyd was brought down on October 22, 1934. It was in July 1935, nine months after Floyd's death, that the BOI was renamed the Federal Bureau of Investigation (FBI).
