Blooper

When Nick Adams, playing John Dillinger, is trying to pick up his girlfriend (Mary Ann Mobley) by the car, she twice calls him "Nick." He even says (while laughing), "The name's Johnny, you ass..."

Nighttime scenes were filmed during daylight hours. Not only were filters NOT used, the film was not even underexposed to give the appearance of darkness. Instead everything was bright and so well lit that the background detail would stand out where there should have only been at best shadows if not black from the darkness.

When Dillinger fires his Thompson at his friends at the lake, squibs have been placed to simulate bullets striking the ground. BUT in this area there clearly was a trench where those squibs were buried.

Most of the clothing is from the 1960s not the 1930s when this film is suppose to be taking place.

When Dillinger first goes to meet the gangster Rocco, a car parked on the street appears to be 1947 Chevrolet, yet this scene is set in about 1928.

During the bank robbery scene set in about 1928 various cars appear to be more recent than 1928, including what appears to be a 1939 Hudson and a 1935 Ford.

Set in the 1930s, but hairstyles, make up and mannerisms are all strictly mid-1960s.

The armored truck in the 1930s sequence is a 1950s model.

When Dillinger breaks Floyd and Nelson out of the work detail from the Indiana State Prison, he ran through some pretty rugged terrain, similar to that of the Sierra Nevada. BUT there are NO mountains in Indiana.

Robert Conrad never bothers to alter his "actor's diction" to reflect Pretty Boy Floyd's uneducated, Georgia origin. John Ashley also neglects to portray Baby Face Nelson's poor immigrant origins.
