Throughout the first half of the film, Clanton is sliding down hills, crawling on the ground, and riding horses that are kicking up dust, yet during the closeups, his Union uniform is always clean and crisp.
In several scenes immediately after being shot in the leg, Clanton's pant leg shows no holes or signs of blood.
Clanton is seen pouring bourbon under his bandage. He pours for about seven seconds, yet his pants, the bandage and his leg never show signs of getting wet. When he takes the bottle out from behind the bandage, it does not appear to have any less liquid in it.
When Clanton meets with Mrs. Fowler in her hotel room, he puts her gun in his waist band and then puts his hands on his hips. The camera angle changes, and his arms are straight down at his side.
When Clanton discusses his plans to get even with Matthew Fowler, Clanton is sitting at a table, and there is about a foot between him and Younger. The camera angle changes, and Younger is ,so close that his elbow is actually in front of Clanton's elbow as they sit at the table.
One of the wanted posters or newspapers headlines shown says "Quantrell's Raiders." The proper spelling is Quantrill.
