The Night of the Burning Diamond - S1-E26
Revealing mistake: Artemus is sampling beef stroganoff from a pot on the stove. He then carries the kettle by its swinging handle across the room, tilting it just enough to reveal to the camera that it's really empty. (00:43:10)
The Night of the Burning Diamond - S1-E26
Continuity mistake: Right before the second freeze frame, the invisible Midas knocks out Gordon who ends up on the floor at the foot of the staircase. Midas knocks out West who ends up on the floor at the foot of the staircase in the same spot where Gordon was, but who is no longer there.
The Night of the Burning Diamond - S1-E26
Continuity mistake: Before the third freeze frame when Midas is outside with West and Gordon, all the people around them are motionless. Midas suspends his flask above his left shoulder. The next camera shot shows the flask several inches lower. Then, the shot from behind Midas shows the flask suspended back to its original position above his left shoulder. During this outside scene, there was a slight breeze which caused both the curtains of the coach to move as well as the lady's lower dress (the one standing behind Midas). When the three move inside, the people suddenly "freeze", but the woman's cape is still slightly moving as well as the gentlemen on the screen's right. When they go into the gallery which houses the jewelry, the motionless actors are not as still as the ones who were outside.
The Night of the Burning Diamond - S1-E26
Continuity mistake: The scene right before the third freeze frame shows the iron gates slowly closing behind West and Gordon. There are three vertical rows of bars showing on each side of the gate. When Midas turns around and walks towards them, there is only one vertical bar showing on each side, and the gates have stopped closing.
The Night of the Burning Diamond - S1-E26
Continuity mistake: In the first scene, West and the Minister are viewing the Kara diamond encased in a transparent protective cube. As they walk to the window, in the background one can see the protective cube, however, the diamond is no longer there. The protective cube explodes revealing the diamond is missing - however, it was already missing before the cube exploded.
The Night of the Burning Diamond - S1-E26
Continuity mistake: Between the first and second freeze frames, an envoy from Washington is at the boxcar door. In the background, one can see somewhat large trees and a large size mountain. The train's close-up for this scene shows the trees and mountains at a much smaller scale.
The Night of the Burning Diamond - S1-E26
Continuity mistake: In the fight scene before the second freeze frame, as West is about to head down the staircase, his pants rip at the seam below the zipper. Throughout the fight, this rip does not show again.
The Night of the Burning Diamond - S1-E26
Revealing mistake: In the fight scene before the second freeze frame during the fight scene, the splicing of the film is off because we see the stationary West shifting a few inches as Midas appears and disappears on the staircase in front of him.
The Night of the Murderous Spring - S1-E27
Continuity mistake: When Dr. Loveless falls from the sill of the double window, the right half of the frame is open (the camera view being from the outside looking in). When West rushes outside to find the "body" missing, the right frame has closed itself and the left is now open. (00:08:40)
The Night of the Murderous Spring - S1-E27
Revealing mistake: Kitten bends apart the cell bars, allowing West and Gordon to escape. But when they brush against it on the way out, one of the "iron" bars gives, flexing like the rubber that it probably is. (00:40:30)
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.
The Night of the Sudden Plague - S1-E28
Continuity mistake: West draws a chalk outline around Arte, but leaves a large gap at the top, on the right side of the figure's head. A few shots later, the gap has filled itself in. (00:43:25)
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.
