The Night of the Inferno - S1-E1
Audio problem: The scene begins with Artie sitting in a rainstorm. Then, when the wagon carrying West arrives, the rain stops, but the sound of the rain is heard through the duration of the scene.
The Night of the Deadly Bed - S1-E2
Continuity mistake: After the opening credits, West is riding on an open field of short grass to meet his personal train - both train and West stop. West's close-up shot shows a large tree directly behind him - this is impossible for there were no trees close to him in the previous shot.
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.
The Night of the Deadly Bed - S1-E2
Continuity mistake: The first transformed freeze frame for this episode appears on the upper right side which is different from the pilot's lower left side. Also, this episode's freeze frame image appears looking like a grainy photo when compared to the pilot's pencil sketch-like image.

The Night of Sudden Death - S1-E4
Continuity mistake: In the scene after the first freeze frame, Corinne is affixed on a round arrow target. Corinne's body keeps changing positions even though the target has stopped spinning. First long shot, she is horizontal with her head at #3. The close-up has her almost vertical with her head at #1. Next close-up, her head is at #2. Following long shot, she is horizontal (head at #3). This keeps occurring throughout this scene.
The Night of the Casual Killer - S1-E5
Continuity mistake: Last scene shows the boxcar in the middle of dirt and short grass. The scene ends with the train moving. Seen near the tracks is a fence of rotting wooden stakes that were not there in the previous shot.
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 That Terror Stalked the Town - S1-E10
Continuity mistake: When Dr. Loveless records his and West's conversation, West says "You belong in jail." When Dr. Loveless plays the recording for Janus in a subsequent scene, West says "Jail is where you belong." (00:14:05 - 00:16:40)
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 That Terror Stalked the Town - S1-E10
Revealing mistake: During the final scene where West and his double, Janus, are shooting at one another, the two look identical to one another. West goes to the roof and jumps off onto Janus who is by the cannon. However, the revealing mistake is the original looking Janus is playing the role of West diving off the roof, and the one who is fighting Robert Conrad who is supposed to be playing his double, Janus, is standing by the cannon. When the two begin to fight on the ground, one should not be able to tell the two apart, but it is apparent the faces are different. The mistake is fixed when the two get off the ground and now both fighters look like West.
