Character mistake: During the fight in the double deuce where Wesley brings Jimmy in to take all the bouncers on, Jimmy takes on Wade, and Dalton comes to his rescue. Afterwards Wade says to Dalton 'same town new story', when in fact the line should have been, 'new town same story'.
Suggested correction: Wade said it that way on purpose. He was alluding to the idea that there is something different about this town's situation, compared with all the other towns where it was the same old situation.
Continuity mistake: After the fight ends between Dalton and Jimmy, Jimmy is killed and kicked into the water. When Doc pulls Jimmy's body out and onto the sand, his eyes are wide open. Immediately after from a further camera angle, his eyes are closed before Doc attempts to close them.
Continuity mistake: When Dalton rips the guy's throat out, he wipes his hand on his pants and no blood is on his hand or pants, the next cut shows him looking at his hand full of blood.
Audio problem: When Dalton gets into the bar and the band is playing "road house blues" there is a moment while the singer is away from the mic but his voice is still on.
Revealing mistake: In the first fight in the entire movie, the first guy Dalton punches is bleeding from the nose before Dalton actually makes contact.
Continuity mistake: When the 4 henchmen turn up to fight at the Double Deuce armed with a boot blade, 2 of the henchmen actors are completely different in the inside and outside shots in this scene.
Continuity mistake: After Jimmy's body is fished out of the pond by Doc, his eyes are open, but they are closed in the next shot.
Factual error: Desert and mountain scenery is visible throughout the film despite being set in Missouri; there is no desert anywhere near Missouri, and its only mountains are the Ozarks, which are smaller and more rounded in appearance than those seen in this film.
