The Night of the Bubbling Death - S3-E1
Revealing mistake: West and Gordon burn a perfect circle (unlikely in and of itself) in the metal floor in order to break into the dungeon below. West punches the circle out with his fist, then grasps what should be white-hot edges with his bare hands before jumping through the opening. Even if wood it would still be too hot to touch. (00:32:00)
The Night of the Bubbling Death - S3-E1
Revealing mistake: As West drags the body of a bad guy out of the scene, the supposedly unconscious man is holding his head up so as not to have his head dragged through the dirt. A truly unconscious person's head would flop back on to the ground.
The Night of the Bubbling Death - S3-E1
Revealing mistake: The rock wall visible through the elevator window is not moving up, but rotating.
The Night of the Bubbling Death - S3-E1
Revealing mistake: The arms of the unconscious bad guy West drags by the feet should be dragging above the shoulders, not almost parallel to his body.
The Night of the Bubbling Death - S3-E1
Revealing mistake: The pyrotechnics are visible as a line in the sand that explodes in front of the posse as they begin to pursue West and Gordon.
The Night of the Firebrand - S3-E2
Revealing mistake: Dust is kicked up and tire tracks from the camera vehicles filming the chase scenes are obvious.
The Night of the Firebrand - S3-E2
Revealing mistake: The dynamite sticks West throws at the bad guys do not explode where they land.
The Night of the Firebrand - S3-E2
Revealing mistake: While West chucks dynamite sticks at Sean's men, there is a large rectangular hole billowing smoke near a bad guy's dead body.
The Night of the Assassin - S3-E3
Revealing mistake: The dead Calico Jack twitches as Artie removes his false mustache.
The Night of the Assassin - S3-E3
Revealing mistake: West and Halvorsen attempt escape at night, but the lighting indicates the scene was filmed in broad daylight.
The Night of the Assassin - S3-E3
Revealing mistake: The knife blade Lupita sticks in Artie's throat bends.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: The pyrotechnic explosion is in a different location from where West placed the explosives in the mine.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: The rock wall visible through Leibknicht's elevator window is rotating, when it should be seen moving down.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: The nozzle that sprays the anesthetic that knocks out West is gray and part of the file cabinet in the close up and large enough to be seen in a long shot, while the file cabinets are green and there is no nozzle.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: The scene of the sanitarium burning is obviously superimposed with footage of flames.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: The leather strap securing West to the gurney has already been cut before he cuts it himself.
The Night Dr. Loveless Died - S3-E4
Revealing mistake: A dark stain seen on the red carpet is the path for the kerosene to travel after West shoots down the chandelier and sets the room alight.
The Night of the Circus of Death - S3-E9
Revealing mistake: The single kerosene lamp West lights inside Bronzini's circus wagon not only lights up the entire room, it also impossibly casts his shadow on two different walls at once as he searches the various trunks. (00:14:50)
The Night of the Legion of Death - S3-E12
Revealing mistake: The scar makeup on Montgomery's face begins peeling off as he is giving his speech.
The Night of the Vipers - S3-E18
Revealing mistake: The final gun battle in town has a gunman in a tower shooting at West. The gunman's perch is enclosed on all four sides by a bannister, but when West returns fire, shooting the gunman out of the tower, the bannister in front of the gunman has disappeared, allowing the stuntman a clear path to fall out of it.
