The Night of the Watery Death - S2-E9
Continuity mistake: In the Mermaid Tavern, the abalone shell and West's black hat switch places on the table between takes. (00:02:40)
The Night of the Bottomless Pit - S2-E8
Continuity mistake: When he shows it to West, Mauvais holds the bottle of fire ants differently in the close-up than he does in the full shot. (00:34:30)
The Night of the Bottomless Pit - S2-E8
Continuity mistake: When they attack him, Artemus' cellmates are smacked with a wooden chair, which lands broken but upright on the floor. In the very next shot, though, as Artie throws the exploding cigar, the chair is suddenly lying on its side. (00:25:30)
The Night of the Bottomless Pit - S2-E8
Continuity mistake: While interviewing West, Commandant Mauvais removes his white gloves. But after a quick cut away to West, the gloves are back on again. (00:07:30)
The Night of the Bottomless Pit - S2-E8
Continuity mistake: After Artemus' entrance, Mauvais' left glove disappears and reappears repeatedly as he pours and drinks his wine from the red glass. (00:24:15)
The Night of the Poisonous Posey - S2-E7
Continuity mistake: In the funeral parlor, West is standing with his back to a wooden door. The shot cuts away briefly, then back, and now there's a blue wall behind him. Cut again, and the door is back. (00:19:05)
The Night of the Big Blast - S2-E4
Continuity mistake: While Artemus talks to Lily at her dining table, he clasps his hands behind his back and is standing up straight. When the shot cuts, he's suddenly leaning forward with his left arm extended to the table. (00:11:25)
The Night of the Raven - S2-E3
Continuity mistake: In the reverse angle shot of West's table, the plates, candles and red table cloth are all there - but the huge dish of butter has disappeared. (00:39:20)
The Night of the Raven - S2-E3
Continuity mistake: Because the second one is a painted backdrop, the building across the street from the sheriff's office in the exterior shots looks nothing like the one we can see from inside the office in the next scene. (00:07:00)
The Night of the Man-Eating House - S2-E12
Continuity mistake: West and Gordon drag Day from the haunted house, prop him on the porch and turn away. When they turn back, they're stunned to see that he's aged 30 years. But if you look closely, you can see that the man they prop on the porch is already gray-bearded and shaggy. So why were they surprised? (00:44:30)
The Night of the Vicious Valentine - S2-E20
Continuity mistake: The mannequin arms holding West to Emma Valentine's chair keep changing positions between shots.
The Night of the Amnesiac - S3-E22
Continuity mistake: When amnesiac West emerges from between the buildings, it is dark outside, but when he encounters the cowboy assaulting the woman, it is now suddenly broad daylight.
The Night of the Colonel's Ghost - S2-E24
Continuity mistake: The opening scene of this episode shows the train moving at twilight. West and Gordon are looking out the window, and it is pitch black. Right before West goes outside, the camera shot of the train wheel shows light (either twilight or moonlight) on the wheel. The very next scene has West with the train door open, and it is pitch black outside. (00:00:05 - 00:00:35)
The Night of the Deadly Bed - S1-E2
Continuity mistake: In this second episode, West's chest is clean shaven, whereas in the previous episode, the pilot, his chest is very hairy.
Continuity mistake: "Night of the Bubbling Death": Artemus tosses just one bottle grenade at the pursuing posse of bad guys. In the next shot, however, multiple explosions go off all at the same time in a straight line across the road. (00:14:00)
The Night of the Deadly Blossom - S2-E25
Continuity mistake: When Barclay hangs the bone hatchet back in its place, the outline on the wall supposedly left by the item differs significantly from the artifact itself. (Most noticeable is the upper end: the outline has one long curled tip, but the actual hatchet has two short prongs there.) The outline was apparently drawn without the prop, or from a different prop altogether. (00:12:05)
The Night of the Skulls - S2-E13
Continuity mistake: West crashes through the French doors, breaking out the center section and leaving a partial framework on either side. In the next several shots, the center support and one broken frame reappear and disappear repeatedly. (00:02:30)
The Night of the Man-Eating House - S2-E12
Continuity mistake: Near the end, when they confront Liston Day outside the house, West and Gordon are standing close together in all the frontal shots, but several feet apart in all the reverse angle views. (00:45:30)
The Night of the Poisonous Posey - S2-E7
Continuity mistake: The bad guys throw an unconscious West down a chute into the ice house. He goes in with his arms at his sides, then slides with his arms above his head, and finally lands with both hands folded over his stomach - all while remaining unconscious. (00:30:30)
The Night of the Flying Pie Plate - S2-E6
Continuity mistake: At the end, the wagon tailgate falls open during the scuffle with the bad guys. When West fights his way to the front and drives the wagon away, the tailgate has somehow tied itself up again. (00:48:00)
