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: As with many shows, the outside doesn't even come close to matching the inside layout.
Night of Desirable Objects - S2-E2
Revealing mistake: When the typewriter is being used at the end, the keys being pressed don't correspond to the words appearing on the paper. Obvious from the start - the first letter pressed is on the middle row of the keyboard, but the first word typed is "unacceptable".
Revealing mistake: When Briggs disguises himself as Rogosh's defense attorney, the glasses he puts on very obviously have no lenses in them. (00:26:05)
A Sentimental Journey - S1-E19
Revealing mistake: Dialogue in the episode specifically mentions the A2 and A282 roads near Dartford, Kent - the actual roads used were the A1 Barnet by-pass, Galley Lane and Well End Road. The error is revealed by the sight of a road sign that appears just as the Austin Princess Limousine turns on the the main road - the sign shows that the car is not turning on the the A2/A282 near Dartford, but the A1 at Barnet some 40 miles away.
Revealing mistake: In the first shot of the scene where Emma and the others arrive in Storybrooke in their cars, on the left side of the screen, you can see a sign behind a branch. It says "Steveston Museum and Visitor Centre." Steveston is the name of Canadian town which doubles as the town of Storybrooke on Once Upon a Time. (00:07:00)
Revealing mistake: After the Custos's house has been broken into, the next day, the Custos takes a key out of his jacket pocket, unlocks a drawer and takes out a pile of bound papers. When he closes the drawer, he doesn't take the key out of the lock, but he pantomimes his hand returning the key to his pocket.
Single Point of Failure - S1-E2
Revealing mistake: Walter accesses code on the sick girl's laptop to trace the source of the virus - aside from the fact that the code comes straight up a fraction of a second after his hands even touch the keyboard, the code displayed in the black window is for a set of traffic lights, with lines like "Walk/Dont_Walk" and "Green_Arrow/Yellow_Slow." (00:08:10)
On the Road - S2-E1
Revealing mistake: As Cassidy, Tulip, and Jesse are trying to outrun a police car, another cop car enters the road in front of theirs with tires squealing. There are tire skid marks On the Road before the cop car enters, indicating previous takes of the same stunt.
Row Row Row Your Boat on a Rocky Sea - S9-E1
Revealing mistake: Dr. Charles reads the patient's chart. Near the bottom, it says, "Is this enough filler? My hand hurts." (00:19:30)
Ghost Plane - S4-E13
Revealing mistake: When Michaela and Jared arrest Cheryl, Jared takes the money out of her bag and you can see the "For Motion Picture Use Only" designation on the bills. (00:32:00)
Revealing mistake: When Danny is driving Mr. Zhao in his convertible at night, you can really see that the background is a bad fake and since even though Danny is driving with the top down, his hair and clothing does not get ruffled at all by the wind.
Revealing mistake: A runway model drops dead. Linda runs over and checks her. The model blinks, and Linda announces she is dead. (00:06:20)
Revealing mistake: After the flashback to when the girls first met Cece at The Brew, she looks at them through a window outside when she leaves. If you look closely at Cece's hair, you'll notice a green glow, revealing that she's on a green screen. This explains why the image of the girls through the window doesn't look quite right. Cece is also wearing a different dress.
The Vision - S4-E12
Revealing mistake: Two oarsmen (or rowers) in Ragnar's boat, the first in front of us and the second from the back, pretend to have an oar but have none. (00:38:35)
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: In a recent episode (April 08), Lloyd referred to Steve as Simon during a conversation in the Rovers. Simon happens to be Steve's real name. Oops.
Crossroads - S1-E5
Revealing mistake: When Easy is paddling across the river to aid the British soldiers, there is a shot where the person closest to the camera (Bull Randleman) appears to be rowing, but there is nothing in his hands.
Revealing mistake: When the ambulance is hanging over the cliff, in the wide shot you can see the cable holding the ambulance safe. (00:50:40)
Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)
