Visible crew/equipment: Sam enters the livery stable to confront two men who attacked his son. The next scene, filmed from inside the stable, shows Hoss opening the livery stable door and entering. Two crew members, one wearing a blue T-shirt and white shorts, are visible in the distance. They are standing by what appears to be the framework of a building under construction.
Revealing mistake: The courthouse sits above a mine shaft. Blasting in the mine causes a portion of the courthouse to collapse. Fallen bricks, lumber and other debris trap Ben and four others in the vault room beneath the main floor. The shaking of the vault room was obviously simulated by the cameraman shaking the camera back and forth. The table, chair, books, file box and other objects in the room do not move.

Other mistake: Candy is fighting with two of Billy Buckner's men outside their mountain cabin. It is obvious that artificial lighting was used because each man casts two shadows.
Other mistake: Calvin Dorcas enters the Ponderosa home and slumps into a chair. Ben asks, "What happened to you?" Calvin explains that he fell into the river while searching for his granddaughter. However, his clothes and his hair are completely dry.
