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."
Revelations - S1-E10
Revealing mistake: When Kieran looks at his phone in the car, the image of Emma calling him is upside down. The image was added after the filming was done.
Insane in the Germ Brain - S4-E11
Revealing mistake: Near the end of the episode, a zombie hating teenager barges into the church to assassinate brother love. He ends up shooting a choir member instead. Although the gun goes off, blood splatters as if it were a head shot, and the man collapses, there is no point of entry. They forgot to CGI the headshot.
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)
Revealing mistake: The doctors remove a bullet from Elliot's abdomen and place it in a metal medical dish. The bullet appears to be a 9mm or a 9mm short however it has no striations. When a bullet is fired it goes through the barrel picking up the land and grooves of the bore. The bullet should have spirals, this one looks brand-new, like it was just purchased to reload ammunition. (00:48:30 - 00:49:00)
