Revealing mistake: When Wan pets the cat deer for the first time, the animal pushes his head under Wan's arm. The horn then goes right through his shoulder. (00:17:55)
Revealing mistake: When the narrator says that Superman can leap a tall building in a single bound and shows Superman doing so, you can see in the background by some trees, an odd animation glitch. A curved, thin black line by the trees wiggling back and forth. (00:01:55)
Revealing mistake: In the sequence with Zeus and Apollo attacking the intruders, the padding of the jackets' arms they are sinking their teeth into is very noticeable. (00:32:15)
Revealing mistake: Our heroes arrive at an RAF base. Purdey hears a loud aircraft noise and looks up to the sky - cut to shot of a fighter jet. For a few frames after the cut, a caption that reads "The Engineer in the RAF" is just visible. It would seem they 'borrowed' some material from an RAF training film. (Indeed, a later shot of shells exploding was obviously taken from a videotaped TV programme, judging by the 'lag' effect caused by the tube camera that would've been used).
Revealing mistake: When the students see themselves in the TV, (which meant that Skidmore was watching them because Chyna had given her a hidden camera) you can see in the TV that there is actually a green screen on the screen and the video is not actually playing, it was just edited in later.
Robo Koopa - S1-E52
Revealing mistake: When Bunsun walks up to Dr. Nerdnik to free him, an animation mistake is noticable. Bunsun is far away and she walks up to him, and during this whole sequence her body is in front of Dr. Nerdnik, according to the camera's view. (00:04:55)
Revealing mistake: "Who Killed the Rest?" The boat we see speeding toward shore explodes - but in the brief shot of it just before the detonation, the substitution of a model is apparent. The two vessels don't look anything alike. (00:02:00)
Revealing mistake: As Harm & Mac are returning to the US, we are told they are flying out of London Heathrow. But the stock footage of an airport used is actually London Gatwick, identified by its distinctive control tower, and not Heathrow.
Revealing mistake: When Chloe, Eli, Greer, and the rest of the team first go to the alien planet, you can see a car driving in the background to the left of the screen at the beginning of the shot (which wouldn't make sense considering they're on an alien planet). (00:15:40)
Revealing mistake: When Jen is at the cash bar and keeps putting money down, it's the same shot used multiple times since it's the same serial number on the $5. And in one shot they flipped the image to make it look different (you can see the "5" is a reverse image).
Lead Horse Back to Stable - S1-E11
Revealing mistake: When Danny and Colleen are fighting in the rain at the end of the episode and Danny starts explaining how they should stop fighting, raindrops from the camera can be seen dripping from the top left of the screen.
Kugelblitz - S3-E4
Revealing mistake: At the beginning of the episode, as Sissy is signing the papers under the pseudonym Dana Pocket, she is holding cash in her left hand. The words "pictures" "and "film" can be appreciated on the faces of the bills, revealing this is fake money, often used in Hollywood productions.
Revealing mistake: Some of the punches don't land when Linc and C-Note are fighting the bad guys in the garage. This despite the sound indicating they are landing.
Heart of Ice - S1-E3
Revealing mistake: When Batman - disguised as a security guard - opens his utility belt, the belt opens and shows a configuration of buttons and a split-second later, a key card materializes out of thin air in front of the buttons. (00:11:30)
Chapter 7: The Reckoning - S1-E7
Revealing mistake: There's some sleight of hand involved when Cara gets her cup of tea from the repurposed IG-11. Maybe it was costly to have the animatronic arm working to the point of actually supporting the cup and hand it to her, so pay attention to what Cara actually does; Gina Carano is ALREADY holding the cup, taps the mechanical hand with it as if the fingers just released it from their grasp, and retrieves it. (00:11:50)
Revealing mistake: When the target's iPhone rings and Christopher Chance answers it, he swipes his finger across the bottom of the screen, which is the regular gesture to answer a call on the iPhone. Trouble is that we see the screen at the time, and it's not showing an incoming call, just some sort of list - he swipes his finger over nothing of any significance at all.
Not Kansas - S3-E21
Revealing mistake: As the guy fires the machine gun at Guardian, there's a closeup of bullet casings falling to the ground, but they're not just empty casings, they're fired blank rounds.
Revealing mistake: A citizen just reported the armed robbery. In an interior shot of the patrol car, supposedly fast driving down the streets of Manhattan, the pedals of the car are visible in the left part of The Frame; there's no foot on the accelerator. They filmed a close-up of the radio inside a still car. (00:02:35)
Revealing mistake: When Ms. Haman is shot by the soldiers, the moment that the gunshot that hits her is heard, and she is shot, there is already a massive, thick blood stain on her dress from where she is bleeding from. No gunshot wound on the planet can create an amount of blood that massive or thick in an instant. The blood stain was likely applied to her dress before filming the shot. (01:17:52)
Revealing mistake: Near the end of the battle at the end of the episode, we see some Japanese troops coming out from the jungle. The Marines then shoot a machine gun, killing them. But pay attention to the ammo belt. All the bullets are blanks. (00:38:50)
