Continuity mistake: When Eden confronts Kinsey by the lockers, as the angle changes so does Kinsey's arm. In some shots, she has her arms crossed and the locker door is closed, in some shots she has one arm up, holding the (open) locker door.
The Graveyard of What Might Be - S1-E2
Continuity mistake: In the library, Maggie is holding on to a stanchion with her right hand as she introduces herself to Vic, but the quick frontal shot of her shows Maggie holding it with her left hand.
Factual error: The British Army soldiers are not wearing British Army uniforms or carrying British Army weapons and some of them have beards, which are not permitted to British Army soldiers.
Deux Amours - S1-E5
Continuity mistake: Daryl fights the walker on the ship after it kills the other prisoner. He gets backed into a corner and jumps off the boat just as the explosions are happening. The walker he was fighting disappears.
Other mistake: The Zeds infect others through directly touching them. This rule extends to touching their clothes and backpacks, which makes no sense.
Continuity mistake: When Randi is in her tent working on her thesis, the computer is on. When something hits the tent, she almost drops her computer which now has a black screen, indicating that it is off. When the werewolf rips through the tent, the computer is now back on.
Factual error: Sir John Franklin, Francis Crozier and James Fitzjames all wear a crown over an anchor on their epaulettes, the rank badge for a captain with over three years in rank. This is correct for Franklin and Crozier, but Fitzjames only held the rank of commander, and should therefore only be wearing an anchor on his epaulettes.
Continuity mistake: When Jake walks away at the beginning of the episode and the homeowner notices the butcher knife is gone, the way she has her hands resting on the moneybox changes between cuts.
Pride Parade - S5-E3
Factual error: Nandor manages to fly up to space, then loses control and falls back to earth in a fireball as he reenters the atmosphere. But objects reentering the atmosphere only get hot because they're generally travelling at immense speeds, 7-12 kilometers per second. Nandor just floated straight up, then falls straight back down. When Felix Baumgartner parachuted from the edge of space his maximum speed was about 1,300 km/h, and he didn't catch fire.
Continuity mistake: As Rick is getting informed about the CRM's future plans, he is holding his knife under the table. The next shot shows his hand on the table, before showing his hand holding the knife under the table again. (00:23:50)
Welcome to Hotel del Luna - S1-E1
Continuity mistake: When Man-wol is speaking with an employee about the diamonds on her desk, whilst she says "Fine, this should be enough", her hands change position between shots. (00:40:30)
Plot hole: The powerful 'amulet of protection' makes the bullets strike the shooters instead of John. Clearly it works not just against magic and other ethereal threats, but also against physical attacks. So why does he almost get knocked over by a car? True, he isn't seriously injured, but he was thrown to the ground. The amulet should have pulverised that car or bounced it at least two blocks away.
Every Litter Bit Hurts/As You Wish/Take a Hike - S1-E5
Continuity mistake: Take a Hike: When Lumpy is dragging the other characters in the stretcher, Toothy's arm falls off. Later on, when Lumpy is running from the bear, his arm is back. (00:19:29)
Deliberate mistake: The police force in the town is the Gendarmerie, the standard issued firearm is the Sig Sauer P2022 in 9mm. The police officers on this show carry a Beretta and not the 9x19mm one which is the model 92fs, they carry a never issued Beretta 84 chambered in .32 acp or 9mm short. Plus they use some weird holster where the gun arches out and hangs low like a cowboy holster and dangles around. Easy for a suspect to gain control of the officers gun and this happened in this episode.
Sucker Bait - S1-E7
Factual error: It is quite true that atoms that do not occur naturally are bad for humans. However, in a space age as this story's, that would apply to most or even all planets. It would be a well known risk that didn't require an abnormal specialist to diagnose. (This fact rarely figures in other SF, because it would severely limit most stories).
Factual error: In Massachusetts, Atticus, Leti and George are attacked by the local sheriff and his deputies, who are patrolling the county roads. In Massachusetts, sheriffs run the county jails, but they do not (and did not) handle routine policing, which is the responsibility only of municipal police departments.
Factual error: The FBI agent introduces himself and says "Mike Weston - I did my thesis on Joe Carol at the academy." FBI agents are required to have a university degree, but they don't write thesis' at the academy. A person is either in a university or at Quantico getting trained. They are not writing papers at Quantico. They need the degree beforehand to get in. (00:10:30 - 00:11:30)
Other mistake: Jesus leaves his home with a double barrel break-action shotgun and an ammunition belt holding extra shot-shells. In the next scene Jesus is walking in the street with the shotgun and no ammunition belt, it magically vanished. The shotgun only has a capacity for 2 shot-shells, then it needs to be reloaded, or it can be reloaded after one is only fired, that procedure is called a top-off. He fires 1 round at the mayor and two inside Elena's home which makes three. He never reloads. (00:32:50 - 00:34:40)
Continuity mistake: The crossbow at the bottom of the bed disappears and reappears throughout the movie.
Audio problem: When Ilonka is speaking with her father about going to Brightcliff Hospice, in a shot where the camera is behind her, she says "Lots of foster kids. I mean, kids on their own" and the line appears to sync with her mouth perfectly. But immediately after finishing that line, she starts saying "It's a place for teenagers to transition on their own terms", and her mouth doesn't appear to sync up with the audio at all. (00:12:50)
