Revealing mistake: The woman becomes possessed while the police are attempting to arrest her. She turns her head around and cracks her shoulders so she can walk at them backwards. They did not change her hand positions, so her right hand is where her left should be and vice versa. (00:11:00)
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.
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.
Revealing mistake: In the first shot of Glen walking and the cart collector following him, everything appears as normal, however when the camera cuts to a longer shot, everything is now mirrored. (00:04:52)
