The Night of the Returning Dead - S2-E5
Continuity mistake: It's just past nightfall when the townspeople enter the courthouse. They aren't there more than half an hour, yet it's daylight when they emerge. Then a shot from inside shows that it's night again. (00:28:30 - 00:33:30)
Continuity mistake: "Night of the Bubbling Death": West uses a glass cutter to retrieve the US Constitution, which was lying flat under a covering sheet of glass. But when he reaches in and pulls the document free, it is no longer flat, but is rolled up. (00:36:15)
The Night of the Skulls - S2-E13
Continuity mistake: West's sword fight ends when his opponent falls through a window after dropping his weapon. In the next shot, the dropped blade has moved several feet to the center of the floor, and West's sword has vanished altogether. (00:30:00)
Continuity mistake: "Night of the Bubbling Death": The dust left on West's jacket after the fight changes patterns several times, then disappears altogether when he enters the building. A shot of his feet shows us that his formerly dusty boots also polished themselves. (00:04:00)
The Night That Terror Stalked the Town - S1-E10
Continuity mistake: West pulls a gun on Artemus and places it just behind his head. In the next shot, though, West is standing two feet away and the gun is nowhere near Artemus' head. (00:45:30)
The Night of the Man-Eating House - S2-E12
Continuity mistake: West tosses a small grenade at the French doors. We see it hit and explode without breaking a single pane or crosspiece. It just makes smoke and blackens the surface. After a shot of West and Gordon, we cut back to the door and it's now a broken ruin with no glass and the wood framing destroyed. Delayed action bomb? (00:13:00)
The Night of the Janus - S4-E18
Continuity mistake: In the first boxcar scene, the train is shown standing among brown dirt and dead brush with the trees far off in the distant. When West opens the door to leave, there is a tree right in front of the door.
The Night of Montezuma's Hordes - S3-E8
Continuity mistake: West has a different hairstyle as it is parted down the middle when he is fighting outside the Nugget Saloon. In the inside fight and throughout this episode, there is no part in his hair - with the only exception of this outside fight. (00:13:30)
The Night of the Glowing Corpse - S1-E7
Continuity mistake: Near the end of the episode when West walks into the mansion where the meeting is behind held, just as he enters, Lt. Armand Renard can be seen talking to Artemus at the bottom of the staircase, but Renard died earlier in the episode. They obviously filmed this scene at the same time as the first scene, but missed that continuity error in the editing. (00:46:40)
The Night of the Raven - S2-E3
Continuity mistake: Dr. Loveless' henchmen remove Artemus' leg chain. But a few scenes later, he's shown asleep in a chair, and the chain is back around his ankle. (00:28:35)
The Night of Miguelito's Revenge - S4-E12
Continuity mistake: When West and Pike pour a drink for "absent friend" Arte, the glass is placed between a newspaper and a silver dish. In the following close-up, the paper and dish have disappeared and the glass sits alone on the table. (00:49:50)
The Night of the Amnesiac - S3-E22
Continuity mistake: As Gordon interrogates Crotty, Crotty raises his cigar to his face twice.
The Night of the Legion of Death - S3-E12
Continuity mistake: West and Gordon are being chased by members of the Legion, who wear green uniforms and black hats, but the stock footage of the chase shows the blue uniforms of regular U.S. Cavalry troopers.
The Night of the Legion of Death - S3-E12
Continuity mistake: The stock footage of West and Gordon being chased in the wagon by the Legion soldiers shows eight troopers, but other scenes show only four.
The Night of the Legion of Death - S3-E12
Continuity mistake: West sprinkles a thin line of powder into a circular shape surrounding him, but before the powder ignites and burns through the floor, it is thicker and has a wider circumference.
The Night of the Legion of Death - S3-E12
Continuity mistake: The stock footage of the wagon West is driving has a large opening in the front of the canopy as he is being chase down by the horsemen, but the close ups of West driving show a much smaller canopy on the wagon.
The Night of the Legion of Death - S3-E12
Continuity mistake: Stock footage of the wagon West drives to escape the horsemen shows a team of four horses, but the closer scenes show a team of only two horses pulling the wagon.
The Night of the Legion of Death - S3-E12
Continuity mistake: The long shots of the wagon West is driving shows it being chased by the horsemen in moonlight, lighting up the terrain showing trees, rocks, and scrub, but the close up of West driving shows nothing but blackness in the background.
The Night of the Cadre - S2-E26
Continuity mistake: After a bomb explodes near West, when he stands up, there is a rip midway on the seam of the seat of his pants. In the subsequent fight scene, the tear is no longer visible. (00:28:25)
The Night of the Deadly Blossom - S2-E25
Continuity mistake: In the final scene of this episode, the train is shown at twilight. When Gordon leaves the private box car, it is pitch black outside. The last shot of the episode shows the train in twilight again. (00:47:10 - 00:47:45)
