Alias Smith and Jones (1971) - 14 major mistakes

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.

Plot hole: Well within earshot of the others in the small room, Curry comments to Heyes (purely for the viewers' benefit, since Heyes already knows it) that if Lom Trevors is killed, their amnesty will go with him. This information should have blown their cover, but for some strange (and unbelievable) reason, no one wonders what he's talking about.

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: 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.

Continuity: While he's working to open the safe, Heyes is wearing his coat. Then he isn't. Then he is again.

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.

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: 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: Heyes and Curry ride out of town wearing shirts and vests. Both turn to look behind them when they hear the posse coming. As they spur their horses into a gallop, they're suddenly wearing heavy coats.

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

Plot hole: Though they often had to race off leaving everything behind, and never carried more than two small saddlebags and a thin blanket roll on their horses, Heyes and Curry somehow always had the same heavy winter coats to wear, and the same dress hats and suits to change into whenever needed. Ben Murphy called this phenomenon "our magic saddlebags."
