Episode #1.1 - S1-E1
Revealing mistake: The "game" Lily is playing on her iPad is actually a 14-second video downloaded 10/16/2020, as visible from the iOS photo gallery UI bordering the tablet. (00:12:04)
Revealing mistake: The dead victim is being examined in the morgue, right as the mortician says "the kid put up a fight" the dead victim swallows as she strokes his hair and says the word "fight." (00:09:35)
Revealing mistake: In the arcade the killer talks to his helper while playing a pinball machine. He plays very agitated and strongly. But if you look closer at the below end of the playfield you see that there is no ball and the flippers aren't moving. (00:23:50 - 00:24:48)
Revealing mistake: When Major Popov aims the rocket launcher at the Venus probe, there is no rocket in the launcher- it is just an empty tube.

Revealing mistake: In the morgue the wall has fake body chambers. Look at number 6 and Boyce the wall stops and a door behind it.
Revealing mistake: In the scene where the wife comes in to the morgue to view her dead husband, who she helped to euthanize, the dead man is breathing throughout the whole scene. You can see the sheet rising and falling at his stomach. (00:22:15 - 00:24:05)
Revealing mistake: When Kim is leaving Gatwood Oil and realises her car is stuck in the dirt, the car is still in park. No wonder it's not going anywhere.
Revealing mistake: About 20 minutes in, the cops have a newspaper with the headline about the two guys they killed. They turn to page two which has a story about the next guy they are planning to kill. If you look at the picture, it is glued onto the story page. The left side is lifted. The actor must have been hired after the printing.
Revealing mistake: In the forensics lab Carol Wilson is saying to others that the rat caught on the ship is healthy. In the ensuing conversation the respirators they are wearing are so ill fitting as to be pointless - Carol's mask does not even touch her nose. (00:26:00 - 00:27:00)
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.

Revealing mistake: In the second of two cases, a man who shot and killed his girlfriend is stopped by police. He is shown pointing his handgun out of the car window, but it is obvious that the barrel and recoil spring assembly of the gun have been removed. (00:41:03)

Deathfist 5: Major Crimes Unit - S2-E15
Revealing mistake: There's a stunt featuring two-way too obvious body doubles for Kelly Hu and Gretchen Egolf rolling over a table; not only the stunt itself is rather underwhelming and blatant, but also the objects on the table disappear just so the two can perform it.
Episode #3.4 - S3-E4
Revealing mistake: After DC Louise Gardiner dies, DCI Jim Keats closes her eyelids. She swallows as he moves his hand across her face.

Ashes, Ashes - S1-E6
