Hard Times - S1-E3
Other mistake: Crowley shows acute discomfort while inside the church with Aziraphale and the Nazi spies as he is on consecrated ground. However, (spoiler alert) once the bomb destroys the church he is perfectly comfortable. The key word here is "ground" - it is the land upon which the church stands that is consecrated, not the building itself. (This allows churches to be rebuilt if they are demolished or destroyed.) Crowley should still be in considerable discomfort after the church has been blown up.
Visible crew/equipment: When one of the guards cries "Destroy it!" watch to the left of Karga and you'll see a crew member in jeans hiding behind a wall. This was later edited out on Disney+. (00:18:54)
Factual error: Bill wears four medal ribbons, in order: Diamond Jubilee Medal (awarded to all people with five years' service in a British uniformed service in 2012), Golden Jubilee Medal (the same in 2002), Queen's Police Medal (a very prestigious award, a handful of which are awarded every year to long-serving police officers for exceptional service) and Police Long Service and Good Conduct Medal (awarded for 20 years' unblemished service in the British police). Not only are these in the wrong order (it should be QPM, Golden Jubilee, Diamond Jubilee, LS&GCM), but he's not entitled to any of them! He's an American who hasn't previously served in the British police. A chief constable's uniform doesn't just come with medal ribbons for the look of it; only those that have been earned may be worn.
Factual error: Alice and Kate's little reunion underwater is disrupted by policemen that fire at them, and one of the shots reaches the transport truck, ignites it and makes it explode. The scene is baffling; forgetting the complete disregard for fellow policemen in the vehicle, how would bullets have enough strength to penetrate into an armored truck deep underwater, reach a critical weak point from that angle (the truck is upright, they should be barely get to shoot the roof of it) and still underwater cause inside the completely immersed vehicle a spark that would ignite fuel and make the whole truck explode? (00:31:45)
Factual error: After escaping from Danzig, Grzegorz and Konrad flee to Warsaw, then to the eastern, Soviet-occupied part of Poland. They then make their way on foot right across occupied Poland and Germany to join British forces at Dunkirk, a distance of over 1,000 miles. Not a likely journey on foot at any time, let alone across hostile territory in the middle of a war.
Continuity mistake: The amount of blood on Allison blouse decreases after Vanya cuts her throat.
Factual error: The Secretary of the Air Force enters a room. A captain not in uniform salutes him. You do not salute out of uniform, and you do not salute civilians. You stand at attention. (00:09:20)
Character mistake: When Ginnifer Goodwin leaves the supermarket to go the parking garage, the green sign says 1 hour parking Customer's Only. It should say Customers Only, without the apostrophe.
The Happiness of All Mankind - S1-E4
Continuity mistake: When Legasov proposes to use Bio-robots, Scherbina pours 2 glasses of vodka. One glass is about 80% full, another 60%. However, when glasses are placed on the table, they appear to be both filled to 80%. (00:39:27)
Episode #1.1 - S1-E1
Continuity mistake: As Ricky Gervais walks by the school where his nephew is, a "chubby little ginger" shouts "pedo" at him. He stops and holds one of the bars of the railing, third from the pillar. In the close-up, you can count more bars than that, showing he is in a different position altogether. (00:07:00)
A Single Piece Was Lost - S1-E10
Visible crew/equipment: When the Gruenaks attack the Scientist a puppeteer is visible to the right of one of the Gruenaks, just before it grabs the bird cage and throws it onto the Scientist's head. (00:28:18)
Factual error: When Judy gets home and the key isn't working she looks at her iPhone and sees a long list of calls to Steve's mobile phone. This is wrong. IPhone just shows the name once per day and the number of calls in between brackets.
Glorious Five Year Plan - S3-E4
Factual error: The Boys use a Dodge Sprinter to drive around Russia. In Europe and Russia this Sprinter was only sold through Mercedes-Benz.
Continuity mistake: One moment Frankie takes out two shot glasses and a bottle and starts to pour. She pours maybe one-fourth of one glass. The very next shot, both glasses are filled. (00:03:35)
Factual error: George Wigg MP wears an RAF tie. Wigg served in the Royal Tank Corps and the Army Educational Corps, but he was never in the RAF. Few men would wear a regimental tie to which they weren't entitled, least of all someone in the public eye, where it would be immediately picked up and ridiculed. Especially given this is set only 17 years after the war (and only just after compulsory National Service ended) at a time when most men were entitled to wear some sort of regimental tie and recognised fellow veterans by the design of their tie.
Audio problem: The zombie chasing the man gets tangled on a wire fence and gets shot in the head. When the bullet impacts his skull he makes a grunting pain noise just like everybody else who gets shots in movies makes the same grunt. First of all zombies don't feel, so how can he express pain, and secondly when people get shot and die they don't grunt, they drop dead. (00:09:30 - 00:10:00)
Pathfinder - S2-E4
Factual error: Ed and Gordo are both flying NASA T-38 Talon aircraft from Houston to the Cape. NASA is a civilian space agency, and all of its planes are registered as civilian aircraft. But Ed's T-38 is shown in one shot as having US Air Force registration.
Continuity mistake: In s02e09, "Enter the Dragon", when Father Jun shoots the second Irishman, he's holding the pistol with both hands. But in the next shot, he's back to holding it with one hand.
Continuity mistake: When Geralt fights the Striga, he ends up lying on his back with the Striga on top of him. To escape, he uses his magic to "punch" through the floor. The first attempt fails, its only effect is to blow away some dead leaves. At the second attempt a few seconds after, leaves are back on the floor.
Rallying to Keep the Game Alive - S1-E4
Audio problem: When the couple is having dinner there's a shot from behind him saying "but you're right." The movement of his jaw and mouth are totally out of sync.
