Episode #1.3 - S1-E3
Continuity mistake: Dr. Armstrong shouts at Vera to stop the high pitched noise she is making with her glass. She does, and then resumes it; the turns her finger counterclockwise under one camera angle, clockwise under the other. (00:09:25)
Episode #1.3 - S1-E3
Continuity mistake: After the orgiastic party, the doctor is slow-dancing with a nearly passed out Blore. He tells him to look at the other couple; between shots Blore's head (as indicated by the hat) is tilted in opposite directions. (00:19:30)
Episode #1.3 - S1-E3
Revealing mistake: When Lombard looks at Vera after realizing she stole his gun, the unruly wisps of hair are on his left temple, while in the rest of the scene they are on his right. The shot is mirrored, as you can see that suddenly it's like he's wearing a woman's shirt, with buttons on the left. (00:38:45)
Episode #1.3 - S1-E3
Plot hole: The killer is meant to create the perfect crime, but the angle of the shot would make obvious to any forensics examiner that it's a suicide. There is practically no possibility for a person supposedly positioned across a long dining table to kill someone else with a shot under the chin. (00:55:50)
Episode #1.3 - S1-E3
Continuity mistake: Vera fires the gun several times, and later tells Justice Wargrave that the gun is empty, meaning that all the cartridges in it would be spent. When the judge loads his one bullet into the chamber, he does so in a gun where all five cartridge svisible are unspent.
Episode #1.3 - S1-E3
Deliberate mistake: When the judge shoots himself, the revolver slides across the table, to fake his murder by someone else. But there is no mechanism in place that explains how he does this, making it appear as if he is able to accurately throw/slide the gun after shooting himself. In the original novel, he used a rubber band to achieve the effect, but he is not shown setting it up here.
