Continuity mistake: Near the end of the episode when West walks into the mansion where the meeting is behind held, just as he enters, Lt. Armand Renard can be seen talking to Artemus at the bottom of the staircase, but Renard died earlier in the episode. They obviously filmed this scene at the same time as the first scene, but missed that continuity error in the editing. (00:46:40)JohnJohnD
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.11291929
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.
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.
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.
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.
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.
Continuity mistake: After the first freeze frame, West is trapped in a pit. The camera angle from above shows him standing on a pail with his arms extended upward - so he can hold on to the beam - as he is waiting for the fuse to thrust him upward. At the moment the fuse propels him upward, the close-up shows West's arms down at his side, but as he is ascending towards the beam his arms are extended upward.11291929
Continuity mistake: In the scene after the second freeze frame, Gordon enters the room where West and Captain Leon are being held. Gordon drops his monocle to the ground and with his foot hides it with the debris on the ground to cover it up. When Gordon leaves, the camera shot shows West picking up the monocle in plain sight with nothing covering it.
