Revealing mistake: When C-Note leaps out of the train, you can see that the man jumping out of the train is a stuntman. He is much chubbier than C-Note (wearing a life vest) and his face is completely different. (00:22:20)
And Then There Were None - S6-E16
Revealing mistake: Samuel is very much dead, laid out on the table in the canning factory employee lounge, but as Sam stands over him, talking about whether or not it was right to gank him, you can see Samuel's chest rising and falling as he breathes. (00:26:30)
Revealing mistake: When they show the soldiers killed by the Dalek, in both the hallway outside the cage and the large room in weapons testing, they show some casings which were ejected from the soldiers' guns. The casings still have projectiles in them. If used, they would have been in magazines and would never fall out like they are shown.
Revealing mistake: Davis, the psychiatrist, is the second man to be killed. Although he was shot at five times, only the first two wounds, which are the highest, give blood, while the lower and later three do not.
Revealing mistake: When Agent Hotchner receives a text from JJ while interviewing the suspect, it is actually a screenshot. You can see Camera Roll in the upper left hand corner, "2 of 2" where JJ's name should be, and the Share/Play/Delete banner at the bottom. It is covered by Agent Hotchner quickly tapping on the screen to clear the banners. (00:16:15)
Revealing mistake: When Toby announces that he's moving to Costa Rica, he gets up and goes to hop the fence. He moves out of frame and when the camera goes back to him, he's been replaced by a stunt double, which can be seen as the double's face is visible after he's scaled the fence. (00:17:15)
Revealing mistake: When Allison is "seeing" the Massey house going up in flames, James flinches when the painting falls off the wall behind him, even though it is only supposed to be happening in Allison's vision.
Revealing mistake: Kevin McKidd's Scottish accent appears every now and then. For example in this episode, when he says that Marc Antony "negotiates with a whore and a dwarf at his side".
Mother and Child in the Bay - S2-E2
Revealing mistake: When Bones and Booth are driving in his SUV talking about Abraham in the Bible, you can see that Bones' side window is lowered almost all the way down, but her hair is perfectly still and not being blown around as it normally would be.
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 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 Melinda goes to Justin's dorm room to speak to him after he dies, the camera pans to his body on the bed and you can see that it's a body double. (00:24:50)
Revealing mistake: Logan gets all the characters to spend spring break at his dad's house. When Zoey finds out Dustin drank all of Quinn's "fratz" she screams his name and runs to go and find him, but despite being meant to be angry you can tell she's laughing.
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)
Saving Face - S3-E3
Revealing mistake: After they drop the casket and Provenza says 'guess you can take it with you!', the close up of the dead girl shows her close her mouth.
