Revealing mistake: When Nero and Gemma are talking, a woman can be seen in the background moving a paint roller up and down without actually touching anything. (00:54:45)
Dr. Quinn, Medicine Woman - S1-E1
Revealing mistake: While Dr. Mike is riding in the wagon with Charlotte and her children, when Charlotte says, "I'd like to ring Sully's neck," a vehicle is visible behind Charlotte's head driving toward the left side of the screen. (00:20:05)
Revealing mistake: When we first see the army of Starks outside Global Dynamics, it's quite obvious that only one of them is actually the actor that plays Stark; the others are merely people who look similar.
End Game (1) - S8-E7
Revealing mistake: Boyd has a video-conversation with Linda on the phone she sent him. On top of the screen you can see how long the video will last (1 minute and 3 seconds), showing it's a pre-recorded video, not an actual live conversation.
Revealing mistake: When Briscoe and Green investigate the auto yard with the stolen, blue SUV, Briscoe handcuffs the owner. When he cuffs him, he turns him, showing his back and his hands behind his back. You can see the actor isn't cuffed, just holding the handcuffs as he walks. (00:06:35)
Revealing mistake: When Grievous falls to the ground as the Gungans throw plasma balls at him, the lance General Tarpals stuck through his torso blatantly clips through the ground. (00:15:03)
Revealing mistake: Right after Ignacio tells Andy and Silas to sit down with him at the diner, it's painfully obvious that the baby that Silas is carrying is a doll.
Revealing mistake: When Wan pets the cat deer for the first time, the animal pushes his head under Wan's arm. The horn then goes right through his shoulder. (00:17:55)
Revealing mistake: When the assistant coach blows the whistle to start the tryout match, coach Shiroyama blinks back into existence next to him during the same shot a second later. (00:14:00)
Revealing mistake: When Iris is sitting in bed recording the message for Barry, she is holding her iPhone so that the start button is on the left side, but the "video record" button appears on the right. Additionally, her right hand covers the speaker area of the phone fully, including the front facing camera. It is impossible for Iris to be recording the video live and reveals that the video footage was recorded ahead of time. The illusion that the video is being recorded by Iris live is further ruined by the fact that the room lighting is turned off in the scene, but the recording is well lit. (00:02:55)
Revealing mistake: Hannah sits in a conference room and pulls a landline phone towards her to dial her friend, asking about the will Owen left. The phone however isn't in any way connected, hence no call could have taken place.
Revealing mistake: When Nathan and Audrey are sitting at the table in The Grey Gull, the extra in the background can be seen bringing a loaded fork inches short of his mouth then fake chewing. This happens a few times before cutting to the ending credits. (00:40:05 - 00:40:55)
Revealing mistake: When Alex is talking to Rebecca Pope at the end of the episode, we hear Alex say "Now I know more about you than my friends." Watch Rebecca's left eye on the right if the screen when she says, "That's pathetic." Someone did a bad job of editing the CGI and we see a phantom eye over her left eyebrow.
Revealing mistake: When Bolivar's assistant comes running out of the theater where she found him, there are New York cabs as well as Toronto cabs in the background. The passing ambulances are marked as from Toronto, not New York.
Revealing mistake: When Bob and Joyce have lunch, Bob pops open a can of soda (which is period appropriate). The scene cuts to Joyce, then back to Bob. It is clear from how he is holding the can, and how he pretends to drink from it, that his newly opened soda is actually empty.
Revealing mistake: When mini is in the bath at the start of the episode you can see the bandeau she is wearing in the bath when she lays back down in the tub, probably to stop her being exposed.
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
With This Ring, I Thee Kill! - S1-E7
Revealing mistake: In the hospital, a male nurse stands by as Rhodes talks to the patient, keeping an eye on all the beeping vital-signs monitors. But there's nothing attached to the man in the bed - no wires, no leads, not even an IV.
