The Night of the Inferno - S1-E1
Revealing mistake: When Liddy's mansion explodes and burns, the switch from real house to cardboard model is very obvious. (00:35:15)
The Night of the Howling Light - S1-E14
Continuity mistake: It's night outside the train's windows - until Artemus looks out at the attacking Indians; then it's day, and in next shot, it's night again. (00:06:55)
The Night of the Howling Light - S1-E14
Continuity mistake: Akima dies with his head tilted to the left. In the next shot, he's managed, even though he's "departed," to tilt his head to the right instead. (00:49:20)
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 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 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 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 Sudden Plague - S1-E28
Revealing mistake: In the opening scene in the saloon when Gordon takes the glass from the motionless bartender's left hand, the bartender's right hand keeps slightly moving the bottle.
The Night of the Murderous Spring - S1-E27
Continuity mistake: In the scene after the opening credits, West's hair is brushed back from his right side. It stays that way for the rest of the scene - as he is shaving, after he is drugged, as he is shooting at Dr. Loveless, as he looks out the window at the fallen Loveless, and as he runs out of hotel looking for Loveless. While West is still outside, Gordon arrives, and West's hair looks as if has gel in it when he is talking with Gordon. After the first freeze frame, West's hair goes back to the non-gel look.
The Night of the Burning Diamond - S1-E26
Continuity mistake: Right before the second freeze frame, the invisible Midas knocks out Gordon who ends up on the floor at the foot of the staircase. Midas knocks out West who ends up on the floor at the foot of the staircase in the same spot where Gordon was, but who is no longer there.
The Night of the Burning Diamond - S1-E26
Continuity mistake: Before the third freeze frame when Midas is outside with West and Gordon, all the people around them are motionless. Midas suspends his flask above his left shoulder. The next camera shot shows the flask several inches lower. Then, the shot from behind Midas shows the flask suspended back to its original position above his left shoulder. During this outside scene, there was a slight breeze which caused both the curtains of the coach to move as well as the lady's lower dress (the one standing behind Midas). When the three move inside, the people suddenly "freeze", but the woman's cape is still slightly moving as well as the gentlemen on the screen's right. When they go into the gallery which houses the jewelry, the motionless actors are not as still as the ones who were outside.
The Night of the Burning Diamond - S1-E26
Continuity mistake: The scene right before the third freeze frame shows the iron gates slowly closing behind West and Gordon. There are three vertical rows of bars showing on each side of the gate. When Midas turns around and walks towards them, there is only one vertical bar showing on each side, and the gates have stopped closing.
The Night of the Burning Diamond - S1-E26
Continuity mistake: In the first scene, West and the Minister are viewing the Kara diamond encased in a transparent protective cube. As they walk to the window, in the background one can see the protective cube, however, the diamond is no longer there. The protective cube explodes revealing the diamond is missing - however, it was already missing before the cube exploded.
The Night of the Burning Diamond - S1-E26
Continuity mistake: Between the first and second freeze frames, an envoy from Washington is at the boxcar door. In the background, one can see somewhat large trees and a large size mountain. The train's close-up for this scene shows the trees and mountains at a much smaller scale.
The Night of the Burning Diamond - S1-E26
Continuity mistake: In the fight scene before the second freeze frame, as West is about to head down the staircase, his pants rip at the seam below the zipper. Throughout the fight, this rip does not show again.
The Night of the Burning Diamond - S1-E26
Revealing mistake: In the fight scene before the second freeze frame during the fight scene, the splicing of the film is off because we see the stationary West shifting a few inches as Midas appears and disappears on the staircase in front of him.
The Night of the Druid's Blood - S1-E24
Continuity mistake: After the first freeze frame, West is trapped in a pit. The camera angle from above shows him standing on a pail with his arms extended upward - so he can hold on to the beam - as he is waiting for the fuse to thrust him upward. At the moment the fuse propels him upward, the close-up shows West's arms down at his side, but as he is ascending towards the beam his arms are extended upward.
The Night of the Freebooters - S1-E25
Continuity mistake: In the scene after the second freeze frame, Gordon enters the room where West and Captain Leon are being held. Gordon drops his monocle to the ground and with his foot hides it with the debris on the ground to cover it up. When Gordon leaves, the camera shot shows West picking up the monocle in plain sight with nothing covering it.
The Night of the Two-Legged Buffalo - S1-E23
Continuity mistake: In the next to last scene when the Prince is jousting against West, West falls on the ground, and his pants are covered with dirt. In the following shots, West's pants are clean.
