The Case of the Missing - S1-E1
Revealing mistake: WPC Softly leans on a model building in Rammel's office, causing it to collapse by stages. The wire that is being pulled to make the model collapse can be seen to the right of the model. (00:21:00)
Revealing mistake: The bullets the priest takes out of the ammunition tray have no primers. (01:01:33)
The Alchemy Murder Case File 1 - S1-E6
Revealing mistake: When Kindaichi shifts the stage screen Miyuki is holding, her fingers are not gripping the sides in the new position. Unless she is keeping it up sticking the back of it to her palms like Spider-man, it is impossible. She does hold it normally in all the other shots. (00:01:55)
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)
The Delivery - S7-E6
Revealing mistake: Eddie's bar has just burned down, and everything is ruined. However, the glasses above the bar are pristine and clean. At the very least, they'd be blackened and smeared by the smoke and soot, even if the heat of the fire hadn't destroyed them. (00:10:28)
Revealing mistake: When Caitlin gets pushed down by the guy stealing her scooter, she hits her head on a rock and blacks out. The 'rock' is seen compressing from its foam design. (00:10:30)
Revealing mistake: When Artie demagnetizes the lab coat, Claudia falls from a high altitude, but when the shot cuts to her landing on the raft, you can see that the actor jumped from a position much closer to the ground. (00:39:00)
Revealing mistake: Rockford is at the public phone with his client; during the scene, the same extras (guy with grey jacket and pink shirt, a nun and others) keep walking keep and forth in the lobby all the time. (00:02:30)
Revealing mistake: While Holmes and Watson are investigating the crime scene, there is a shot of them that shows the dead man's hand. His hand is visibly shaking, revealing the actor is struggling to maintain the position of his hand.
Revealing mistake: When Jamie sits down after rappelling down the canyon wall you can see that he has climbing rope attached to his harness. It's wrapped in duct tape to look like its the rope he and Adam made of duct tape. This may just be a safety line to support his weight if he duct tape rope snaps, but the Mythbusters usually point out any backup safety systems and explain that they are there for caution and don't contribute to the test. (This was explained in the aftershow. It was a safety line required by the shows insurers).
Episode #9.2 - S9-E2
Revealing mistake: Rose's newborn baby, Isabel, is suspiciously large and mature.
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)
The Royal We - S3-E2
Revealing mistake: On the RV of the guy being accused of molesting the girls, someone has written "PERVERT" in red spray paint. At a point you see Lightman next to a car, and the RV in the background, and the text is mirrored reading: "TREVREP", showing that during editing, this shot was flipped. (00:15:30)
Farewell My Beloved Witch - S1-E3
Revealing mistake: When Lupin is saved by Fujiko and is on the ladder, his lower left leg is missing. (00:21:05)
The Sinners Are Much More Fun - S2-E2
Revealing mistake: When Chucky takes a photo of Jake and flees up the chimney, the flash from the camera is very unrealistic. It doesn't cast shadows, nor does it overlay over the room properly. You can tell all they did was use simple effects to make a translucent white shape blink on the bottom corner of the frame.
Revealing mistake: Near the end, you're able to see the device used to blow open the kitchen door to make it look like a bomb went off. (00:34:55)
Revealing mistake: As the RCV enters the gravel field with the bomb, you can see a person in shorts walking casually in the background, despite the area being sealed off.
Revealing mistake: When Roberta Halton knocks Rob unconscious, you can see that the blunt object barely even makes contact with his head.
