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 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 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 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 Brain - S2-E21
Revealing mistake: Mr. Braine fires a mini-rocket at Brendage, killing him. But a poor camera angle reveals the explosive charge going off in the wall more than two feet to Brendage's left. From the angle at which it was fired, the rocket couldn't possibly have hit him. (00:21:45)
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: 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)
