As Deputy Lee (Harry Carey Jnr) is offering Rem (James Arness) coffee in his cell, he begins to sit down and is positioned behind Rem. The camera then switches and Lee is sitting alongside Rem.
When Rem Anderson (James Arness) is brought back from the robbery wounded, and is laid on the table, his girlfriend Janice (Angie Dickinson) checks him and says he's lost a lot of blood and can't be moved. Yet after they leave him, he gets up and staggers around fairly well, with no evidence of blood on him at all.
(at around 45 mins) There is a power pole complete with transformer visible in the background.
When Rem Anderson (James Arness) confronts Ralph Farley as Farley is trying to leave town after spotting Rem, a fistfight ensues. Most of the fist-hitting-face sounds are muted and barely sound like light slaps, some are totally missing, such as the punch from Rem that knocks Farley under a wagon. But all of the other fistfight noises are there, such as wood collapsing when prop posts and railings give way.
