Revealing mistake: On 10/9/06, John entered the storage facility and reached towards the light cord. He formed a fist, as if grasping the cord, but his hand was actually several inches from it. It was clear that he was not actually holding the cord at all, but then he pulled his fist down and the lights went on.
Revealing mistake: On 12/19/03, Sami was attacked by the masked killer in an alley. She breaks away from him or her, does a backflip, and lands near the opposite wall. Ali Sweeney, the actress who plays Sami, has straight blonde hair. During the flip, the stunt double also had blonde hair, but it was very curly.
Revealing mistake: On 2/17/06, Kate was looking at a picture of Carrie and Austin on her cell phone. The cell phone wasn't held perfectly still, and whenever it moved there was a jerky movement of the picture. The picture had been added in post-production, rather than actually being displayed on the phone, and it became obvious every time the image moved.
Revealing mistake: On 1/26/04, the big, muscular animal handler was struck very lightly in the back of the shoulder, with what looked like a flimsy rubber or plastic object, and fell unconscious. It's ludicrous to imagine that such a weak "blow" could even injure that man at all, let alone knock him out.
Revealing mistake: On 11/20/03, the killer sends Bo a video image of Caroline on a PDA. You can see the "Caroline in Hell" effect wobbling around on the screen of the PDA where it's been superimposed in post-production.
Revealing mistake: On 4/6/16, Deimos researches Nicole on the internet and finds a full biographical profile of her. However, the contents of the page can be recognized as coming from the soapcentral.com page on the character, and it contains a lot of obscure, private details about the character written in conversational language, pertaining to things that would not be known to the fictional public (but are known to viewers of the show). For example, there is a "Crimes Committed" section that includes "Framed Arianna Hernandez for the Salem Muggings" and "Hid evidence and then lied to police about having proof that Kristen drugged and raped Eric."
