The Night That Terror Stalked the Town - S1-E10
Continuity mistake: Three fourths into this episode, West is in a room with an hourglass. The hourglass shows a few grains of sand before it empties. Next shot is of Gordon trying to get through the chained gates. Camera shot back to West's room, which shows a fuller hourglass with more sand, which lasts for minutes as this episode continues, until all the sand empties from the top.
The Night of the Red-Eyed Madmen - S1-E11
Continuity mistake: Half way through this episode, the private train is standing still surrounded by dirt and short grass. However, when the private boxcar door opens, there are very large trees and bushes a few feet from the door.
The Night of the Red-Eyed Madmen - S1-E11
Continuity mistake: The opening of the last scene shows the train moving through an area with large trees along both sides of the track. The closing scene shows the train in an arid area with uneven rotting wooden posts and dried up sage grass.
The Night of the Human Trigger - S1-E12
Revealing mistake: In the next to last scene of this episode during the Sawtooth earthquake, while boulders are falling and trees are being uprooted, West, Gordon, and Faith are not struggling to keep their balance so as not to fall, they are just motionless standing - something that cannot happen with such a strong earthquake. The camera, which is shaking, attempts to make it look as if the three are shaking with the earthquake.
The Night of the Human Trigger - S1-E12
Revealing mistake: In the opening earthquake scene right before the freeze frames appear, West and Gordon are in the bar. The glasses and pitcher on the bar by the bartender, the bottles of liquor behind the bartender, the bottle on top of the piano, and the ashtrays on two tables never move out of place, even though other tables have broken, chairs have toppled, the ceiling is destroyed, and the support beam falls. It is obvious the camera is doing the shaking, not the ground.
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 Fatal Trap - S1-E15
Other mistake: Immediately after the opening credits, West has just finished printing a poster. The poster is still on the printing press and shows what was printed face-up. When he prints the next poster, the image is not showing on the face-up side but on the bottom side when he takes it off the printer.
The Night the Dragon Screamed - S1-E17
Continuity mistake: After West saves the man from falling into the spiked pit, they walk to leave but a trap door opens, and they fall into the water. As they get onto the pier, both of them are soaking wet and have wet hair. They crawl out, sit, and start talking. The close-up of their faces, while they talk, shows that both of them now have dry hair.
The Night the Dragon Screamed - S1-E17
Continuity mistake: West tries to stop the moving wall with a rock. In the up close shots, the moving wall is nearing the end of its travel, while the long shots show the wall quite a way back from the end of its travel.
The Night of the Grand Emir - S1-E19
Continuity mistake: In the next to last scene of this episode, while West is fighting, Gordon is seated knocked out. However, the position of Gordon's legs and right arm keep changing positions throughout West's fight.
The Night of the Puppeteer - S1-E21
Revealing mistake: Just before she dances away, the life-size ballerina "puppet" fails to hold her fixed stare and blinks. (00:20:00)
The Night of the Puppeteer - S1-E21
Revealing mistake: Zachariah Skull's bald head has a problem. The latex skull-cap used to cover the actor's hair keeps bubbling and wrinkling as he speaks. (00:43:00)
The Night of the Bars of Hell - S1-E22
Continuity mistake: In the closing scene of this episode, there is a daytime close-up of their boxcar. When Ms. McCoy walks into the boxcar, it is pitch black outside. Ms McCoy leaves after a very short visit. The last shot of the boxcar leaving shows it is nighttime.
The Night of the Bars of Hell - S1-E22
Continuity mistake: Artie inspects the electrical panel on the wall and the throw switch is at a horizontal position. A quick cut later and it is at a slightly lower angle.
The Night of the Two-Legged Buffalo - S1-E23
Continuity mistake: Artemus is knocked unconscious and left alone on the floor of the train car when the prince is kidnapped. When he wakes up, he's lying in a different place and in a different position than before. (00:18:25)
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.
The Night of the Two-Legged Buffalo - S1-E23
Continuity mistake: In the scene before the opening freeze frames occur, a giant mask, hanging on the wall, is shown several times. A close-up of the shape of the tongue before it shoots the arrow is not the same elongated shape which was shown a few seconds earlier.
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.
