The Night of the Eccentrics - S2-E1
Revealing mistake: Tony throws two knives at West - but on the wall where the knives hit, the rectangular openings from which the blades actually emerge are delineated beforehand. Happens again a few scenes later, where slots cut in the door are already there before the knives are thrown. [Spoiler: It's inconsequential to the "revealing" error, but if you play the scene in slow motion, you can see that both times, the knives pop through from the back of the "wall." This is also how the carnival trick is performed.] (00:17:05)
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 Raven - S2-E3
Revealing mistake: When the marshal opens the train's rear door and comes in to arrest Lana, you can see wrinkles in the "sky" outside. It's really a painted cloth backdrop. (00:48:40)
The Night of the Raven - S2-E3
Revealing mistake: The strings used to move Dr. Loveless' plants are visible.
The Night of the Raven - S2-E3
Revealing mistake: In the pit with West and Princess Wanakee is a cat that is obviously superimposed into the scene, as West and Wanakee cast stark shadows, but the cat does not.
The Night of the Big Blast - S2-E4
Revealing mistake: The "corpse" Miklos wheels into Dr. Faustina's laboratory is pretty healthy for a dead guy: you can see his chest moving up and down as he breathes. (00:27:00)
The Night of the Big Blast - S2-E4
Revealing mistake: During the sword fight on the stairs, Artemus' stunt double's face is in plain view in several shots. (00:30:00)
The Night of the Big Blast - S2-E4
Revealing mistake: It is obviously a dummy body that West and Gordon net, then drag behind the carriage before the dummy body explodes.
The Night of the Big Blast - S2-E4
Revealing mistake: The face of the stuntman playing the bomb-carrying Artemus Gordon double is obvious, and looks nothing like Ross Martin, who plays Gordon.
The Night of the Flying Pie Plate - S2-E6
Revealing mistake: After they're carried inside and placed in chairs, one of the "unconscious" women moves her arm into a more comfortable position. (00:33:00)
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 Flying Pie Plate - S2-E6
Revealing mistake: The wires used to open and close the pie plate's entry hatch are visible.
The Night of the Poisonous Posey - S2-E7
Revealing mistake: The rectangular openings from which the knives thrown at West will actually emerge are visible on the door behind him. After the knives "land," the rectangles disappear. (00:18:50)
The Night of the Poisonous Posey - S2-E7
Revealing mistake: West and Gordon are supposedly hiding in opposite corners of the ice house, yet each actor is crouching in the same area with the exact same blocks of plastic ice surrounding him. (00:40:30)
The Night of the Watery Death - S2-E9
Revealing mistake: When the Marquis meets West at the door, the landscape behind him has a give-away flaw: there are prominent wrinkles visible in the cloth backdrop "sky." (00:31:20)
The Night of the Ready-Made Corpse - S2-E11
Revealing mistake: The town of Wickenberg has very peculiar sunlight: it casts shadows in several directions at once. Also notable is the far end of its main street, where a distinct line of demarcation reveals the presence of a painted studio backdrop. (00:00:10)
The Night of the Skulls - S2-E13
Revealing mistake: In the livery stable fight scene between Gordon and Tigo, the tines of the pitchfork Tigo threatens Gordon with wobble, indicating they are made of rubber or a soft material and not metal.
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)
