The Night of the Gypsy Peril - S2-E18
Continuity mistake: The final scene shows a government official entering the private car to take delivery of the sultan. The open door shows that it is pitch black outside, but the final shot of the private train departing shows a very blue sky. (00:48:05 - 00:49:05)
The Night of the Lord of Limbo - S2-E15
Continuity mistake: The last scene of this episode shows the private train in twilight, but when Col. Falk walks in, the outside is pitch black. The last shot shows the moving train again in twilight, not in the dark of night. (00:46:55 - 00:48:05)
The Night of the Lord of Limbo - S2-E15
Factual error: In the upper right side of the screen early in the episode, you can see an airplane flying from the right to left. (00:06:05)
The Night of the Lord of Limbo - S2-E15

The Night of the Infernal Machine - S2-E14
Revealing mistake: Right after Zeno Baroda says, "M'Guigan, I'm going to kill you," he shoots at the door. Before the bullet is discharged, one can see the door is already damaged where the door is about to be shot. Also, one can see the streak (moving from the left to right) of the prop used to cause more damage on the door from the bullet's impact. (00:27:30)
The Night of the Infernal Machine - S2-E14
Continuity mistake: As the toy bear is making its way to Gordon, in the background to the right of the window is a plant on a wooden stand. Next to it is a full length long green curtain with gold tassled fringe at the bottom. Gordon throws the toy bear through the window, but there is no glass breaking. The tall wooden plant stand now is wrapped inside the curtain, and the golden fringe cannot be seen. (00:28:10)
The Night of the Ready-Made Corpse - S2-E11
Continuity mistake: In pursuit of the photographer, West jumps out of the window and lands on a cart of stuffed burlap sacks. West's right shoulder area, back of his suit's jacket's right arm and right pant leg area are very dirty. As West runs after the photographer, his suit keeps getting cleaner and cleaner. (00:04:35)
The Night of the Green Terror - S2-E10
Continuity mistake: When Loveless crawls into the hollow log for protection against the fire, he leaves the horn by the log's entrance. Its mouth piece side is almost touching the log and is parallel to the log. The next shot shows the charred horn perpendicular to the log. (00:45:30)
The Night of the Green Terror - S2-E10

The Night of the Watery Death - S2-E9
Continuity mistake: When West is untied from the pillar, a close-up shot of his foot shows him stepping on the wooden plank that activates the force field. The next shot shows him walking on the plank, but the force field was activated before he steps on it (from a wide angle shot). (00:38:50)
The Night of the Watery Death - S2-E9
Other mistake: After West escapes out of the room where he was tied, he is hiding behind a tall plant by the staircase. There is a person dressed in black lying at the top of stairs who ever so slightly moves. After the fight scene, West attempts to leave from the front door where he is met by the Marquis. When West is backing up into the room, as the Marquis says, "Boys!", one of them is now descending down from the top of stairs - no one is lying on the steps or getting up from steps. (00:31:15)
The Night of the Watery Death - S2-E9
Continuity mistake: Halfway through this episode, West's hands are tied to the bedpost. He frees a hidden knife from his lower right sleeve. The close-up of his right wrist shows two rope strands binding him. When West finally gets the knife in the position to cut the rope, only one rope strand is wrapped around his wrist.
The Night of the Bottomless Pit - S2-E8
Continuity mistake: Towards the beginning of this episode when West is first taken to see the commandant, Cochon goes to the rack on the wall to get West a clean shirt. They are standing by the door where Cochon throws the dirty shirt. There are three pegs on the rack, with a shirt hanging on the leftmost peg and rightmost peg. Cochon gets the shirt off the one on the right peg. As they walk away, West's dirty shirt is now on the ground under the left peg. After the meeting with the commodant, West and Cochon leave. Cochon asks for the clean shirt that West is wearing. When Cochon goes back to the rack to get West a replacement shirt, the shirt that was on the far left peg is now on the center peg, but West's dirty shirt is still under the left peg.
The Night of the Bottomless Pit - S2-E8
Continuity mistake: Before the first freeze frame, West passes out on his right side with his head resting on his right bicep. In the next scene when West regains consciousness, he is facing down with his head resting on folded arms - his head on the left forearm.
The Night of the Flying Pie Plate - S2-E6
Revealing mistake: When the townspeople spill out onto the town's streets after hearing the noise from the sky, the horses tied at the hitching posts never move nor flinch through the entire scene and are all in the same pose, indicating the horses are props and not real.
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 Skulls - S2-E13

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 Skulls - S2-E13
Character mistake: There are seven mourners dressed in black surrounding Gordon's casket - three on each side and one by the funeral officiator (who is the disguised Gordon). Later in the scene when West is talking to the disguised Gordon, Gordon says, "How do you like that - six mourners..." (00:05:20 - 00:07:10)
