Factual error: Wheat refers to the hanging of real-life outlaw Black Jack Ketchum. But Ketchum was executed in 1901. Smith & Jones is set in the 1880s.

Continuity: In full shot, Curry is leaning against the courtroom wall to the right of the door. When the shot cuts to a close-up, though, he's on the left side of the door.

Continuity: When Harry tosses the cloth bag toward the well, it lands on bare ground with a few strands of straw nearby. But in long shot, it's surrounded by heaps of straw.

Plot hole: Heyes convinces the deputy that they're not Heyes and Curry and rightfully pins the bank robbery on Harry, who forced him to break into the safe. But it had been previously stressed that only Heyes could have cracked that particular safe, something the governor knew. So the neatly tied-up ending doesn't really work. The governor would still know that Heyes (whose nitroglycerin method was based on a real bank robbery of the era) opened the safe.

Continuity: Harry sets the can of red putty down on the desk in front of Heyes. When he first places it, the label is facing the camera. When the shot cuts to a wider angle, the label has rotated itself 90 degrees and is now facing Heyes.

Continuity: In the sheriff's office at the end, Heyes and Curry instantly switch positions between takes.

Revealing: The outlaws all have their hands tied behind their backs. But the one wearing glasses, apparently unaware that he's in the shot, brings both hands up to push the slipping glasses back up on his nose, then quickly puts his hands behind his back again.

Continuity: When the posse traps the bank robbers in the livery barn, the doors on both ends of the building slide shut, meeting in the middle. But in the exterior shot, as they all exit, one of the same doors that slid shut a moment before now swings open on hinges.

Continuity: All four bank robbers are herded into a cell with their hands tied behind them. When the door is locked, they're still tied. But a few shots later, without enough time for them to have untied each other, all their hands are free.

Factual error: Heyes and Curry spend months at the mine without any razors or knives. Their beards grow out - but their hair doesn't get any longer.

Audio problem: Just before Curry shoots the rattlesnake, Heyes says, "Don't anybody move." But his lips don't move when he says this.

Revealing: All the shots of the pursuing posse are "borrowed" footage, which might never have been obvious - except for the fact that one shot shows us a recognizable Heath and Nick Barkley from "The Big Valley" at the head of the pack.

Continuity: Bridget shoots ten cans off the fence with her rifle. No one goes over to put up more cans, but in the next moment, there are six more cans set up for Curry to shoot off with his revolver.

Continuity: When Heyes and Curry stop Belle's wagon, Heyes is holding his hat in his right hand. When the shot changes angles, the hat jumps instantly into his left hand.

Factual error: Heyes gives Bridget a glowing and accurate description of the Denver Palace Hotel - a landmark that wasn't built until 1892, ten years after the setting here.

Visible crew/equipment: After the street brawl, Heyes, Curry and Stokely walk away arm-in-arm and pass a man in a 20th Century short-sleeved blue shirt with a very 20th Century haircut, leaning on a piece of equipment to the right of the screen - apparently one of the film crew.

Continuity: After getting filthy in a street fight, Curry goes into the hotel and is immediately clean again.

Revealing: When Heyes rides away from the hotel in the beginning, he's passed on the street by a tall man in a white shirt riding a black horse and slouching in the saddle. When the shot cuts back to the front of the hotel, the same extra on the same horse rides by again, going in the opposite direction.

Continuity: Heyes' horse is shot out from under him by the Chiracahua, forcing him to leave it behind and ride double with Curry. But when they return to Apache Springs, Heyes is again riding the same horse that was shot earlier.

Revealing: During the saloon brawl, recycled footage causes Curry to change into his first season hat for a few shots. After the fight, he has his second season hat back on.
