Factual error: An egotistical, prissy and dishonest lawyer like Mr. Fletcher wouldn't make the mistake of allowing his name to be misspelled on his office door. It reads "Winfred Fletcher." His first name, as it's pronounced throughout the episode, is "Winford."

Factual error: Heyes burns the photo - but he shouldn't have been able to. In the 1880s, it should be printed on tin and not on paper.

Audio problem: Final sound edits were incomplete on this episode when star Pete Duel committed suicide, so his dialogue is "looped" by another actor in several places. Though it's an excellent imitation, it is most noticeably not Duel's voice when Heyes and Curry are waiting for Harry in the opening scene, at the campfire with the Tapscotts, and when Harry tells them about the trial's outcome.

Continuity: Gorman's left hand is in two places at once during the card game. We see it resting on his thigh under the table. One shot later, without time for him to move, both his hands are holding his cards.

Continuity: Harker confiscates firearms from five Devil's Hole members who are playing poker in the saloon. The sixth member is down in the tunnel, and didn't turn over his gun. Yet when the outlaws go to collect their weapons, six are given back their side-arms.

Continuity: The stage driver's hat is white when they leave town, black during the trip, and white again when they arrive at the station.

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.

Continuity: Heyes and Curry walk into the saloon covered with trail dust from head to toe. But when they leave, Heyes' hat is spotless.

Factual error: The sheriff and his posse raise huge dust clouds as they gallop down the road. But the stagecoach they're chasing, with four horses and four wheels, is on the same road and isn't raising any dust at all.

Continuity: Blake spies on Heyes, Curry and Louise as they sit together on the picnic blanket. But in the view through his telescopic gunsight, Louise is missing. When the shot returns to the camera's normal POV, she's sitting right between Heyes and Curry, where Blake's sight couldn't possibly have missed her.

Continuity: While Curry and Heyes are panning for gold, the same shot of someone's bare arm and shoulder above the gold pan is inserted several times. But neither Heyes nor Curry is shirtless, and no one else is with them.

Visible crew/equipment: When Heyes and Curry leave the saloon and walk across the street, a microphone mounted on the camera rigging pops up into the shot at the bottom of the frame and follows along beside them. (This is visible in the US aired and vhs versions, but was edited out of both the BBC version and the recent dvd release.)
