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 Poisonous Posey - S2-E7
Continuity mistake: Towards the end of this episode, West is climbing up the latter out of the ice storage room. The seat of his pants are noticeably dirty as are both of his calves' areas. When West exits onto the street, his pants are inexplicably clean during this shootout scene. During West's fight with Brutus, West's entire back - from shoulders to the bottom of the legs of his pants - has been quite dirtied from rolling on the ground. West then runs to fight Sergei. When Sergei falls off the horse, and West is hovering over him, the entire back of West's clothes now seem only to be faintly dusty. When West leaves the fight area to enter into the funeral parlor, his clothes are immaculate.
The Night of the Raven - S2-E3
Continuity mistake: Three fourths into this episode, West is inside the wall of the mouse hole. Wearing his blue suit, he enters a knot in the wall onto a ramp. While sliding down, West is now wearing an emerald green suit. When West is sliding into the octagon container, he is wearing the blue suit again.
The Night of the Golden Cobra - S2-E2
Continuity mistake: At the beginning of the closing scene, their private train is shown moving right next to tall green trees with large mountains directly behind the trees. The final shot of the scene shows the train in a very desert-like location moving towards the trees and mountains which are shown in the far distance.
The Night of the Eccentrics - S2-E1
Revealing mistake: Two scenes after the opening credits, West fights the strongman Titan. When Titan throws West (who is horizontally positioned on Titan's shoulders) down to the ground through the circus tent, a mattress upon which West lands is mistakenly exposed.
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.
