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: When Freeth, Carter and Regan raid the flat, Freeth breaks the door down - the door starts to fall before Freeth hits it.
Revealing mistake: In the first scene, young people are removing scrap from a rooftop. The camera angle changes to look over the rescue team and back at the roof. In the distance, visible in the upper left of the screen, a Canadian flag is waving in the breeze. Also a short while later the camera looks back over the team away from the children, and the CN Tower appears to be in the background. Like many TV shows, Falling Skies was filmed in Canada, but the events are supposed to take place in Massachusetts, USA. (00:00:25 - 00:02:00)
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.
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)
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: 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.
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)
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)
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.
Relics of the Old Republic - S2-E3
Revealing mistake: There are two shots of Sabine while she's repairing the Phantom and talking to Kanan on her comlink where her neck is missing.
Revealing mistake: When everyone is supposed to be frozen, the neighbor girl standing behind the car can be seen moving her hand onto the car. This happens as Monica says "I'm not afraid of you, Wanda." (00:24:25)
Surf'N Turf/Hardcase Returns - S1-E8
Revealing mistake: In "Hardcase Returns" Skidmark uses a digital phone to track a GPS device installed on Turbo's parade car. When the keypad on it is shown, 3 letters are missing. They could have been on the keys that had nothing written on them, but we will never know for sure because nothing is on them.
