The Night of the Big Blast - S2-E4
Visible crew/equipment: At the end of the sword fight, the moving boom shadow is visible on the balustrade at the right of the screen. (00:30:05)
The Night of the Big Blast - S2-E4
Revealing mistake: During the sword fight on the stairs, Artemus' stunt double's face is in plain view in several shots. (00:30:00)
The Night of the Eccentrics - S2-E1
Visible crew/equipment: Behind West, when he's suspended over the electrical field, you can see the shadow of the boom mike and rigging pole moving on the wall. (00:35:05)
The Night of the Raven - S2-E3
Continuity mistake: West and Gordon are ordered to sit on the floor to talk to the diminutive Dr. Loveless at eye level. In all the two-shots, their shoulders are touching. In all the wider angles, they're sitting a foot apart. (00:09:05)
The Night of the Murderous Spring - S1-E27
Revealing mistake: Kitten bends apart the cell bars, allowing West and Gordon to escape. But when they brush against it on the way out, one of the "iron" bars gives, flexing like the rubber that it probably is. (00:40:30)
The Night of the Burning Diamond - S1-E26
Revealing mistake: Artemus is sampling beef stroganoff from a pot on the stove. He then carries the kettle by its swinging handle across the room, tilting it just enough to reveal to the camera that it's really empty. (00:43:10)
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 Inferno - S1-E1
Factual error: Liddy's six-shooter fires seven shots - three at West and four more at the bottles on the table after he escapes. (00:17:50)
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 Miguelito's Revenge - S4-E12
Revealing mistake: At the beginning of the episode, as Jim West walks away from the newsstand vendor and closes the magazine, a 1967 ad for DieHard batteries ("The DieHard Fights the Common Cold") can be seen on the right-hand page of the prop magazine, in a modern sans serif font.
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 the Janus - S4-E18
Revealing mistake: About half way through this episode, the hooded man West is chasing goes through double doors and closes them. West slams his body to open the doors. He steps back to ram his body into the doors again to force them open. Before he does, we see the doors sort of slightly move back and forth (this looks very odd and unnatural) before West slams them open.
The Night of the Pelican - S4-E13
Revealing mistake: Towards the end of the episode when rocket one is fired, it launches very, very slowly with little force/velocity - obviously a prop.
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)
