Factual error: When Detective Inspector Sara Lunt's photograph in uniform is shown on the TV news she is wearing a double row of silver lace below her hat badge. Only chief constables wear this insignia, well above the rank of inspector.
Continuity mistake: On game night when Jack hands Hans the soy dipping sauce, Hans puts it on the left side of the plate. When the shot changes to Jack walking away, the sauce is on the right side.
Episode #1.2 - S1-E2
Factual error: The catalogue of errors made by the SAS team (e.g. being caught out in the open, not posting a watch, not using cover) would be unlikely to be made by an ordinary trained infantryman, let alone an elite special forces unit.
Episode #1.5 - S1-E5
Factual error: The senior police officer's name tag reads "Assistant Commissioner" but he wears the rank insignia of a Deputy Assistant Commissioner.
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
Pompeii's Gate to Hell - S4-E8
Factual error: This episode includes a segment about an abandoned dry dock in San Francisco. At one point, one of the commentators several times refers to the U.S.S. Ward as a "battleship," and marvels that it was built in 17 days. The Ward (DD-139) was a 1200-ton destroyer, not a battleship, and was launched after only 17 days, but then took another two months to complete. By way of comparison, the California (BB-44), an actual battleship of 32,000-tons built during the same time period, too nearly five years to complete.
Factual error: Johann Eck is dressed as a cardinal and Albrecht von Brandenburg addresses him as "Your Eminence" and kisses his ring. In reality, Eck was not a cardinal. Albrecht, however, was. It should be Eck showing deference to him, not vice versa. Albrecht was also only thirty, half the age of the actor playing him.
Factual error: Everyone, including other police officers, addresses the detectives as "Detective" rather than using their ranks of "Inspector" or "Sergeant" as they actually would.
Factual error: The Navy Seals call in air support and provide a fire mission to given coordinates. The targets are engaged with rockets and gatling/chain guns. The UH-60 Black Hawk is shown leaving after the air strike. This UH-60 however only had mini-guns in the doors. The type of UH-60 needed for this action would be the UH-60 DAP, which is configured as a gunship and has no troop carrying capacity. The DAP can carry chain guns, mini-guns, missiles and or rockets. (00:03:00 - 00:03:23)
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.
Character mistake: One of the characters, Agent L, is usually talking to the kids via some gadget with bad audio. In The Golden Gauntlet, the first time she appears on the screen she misnames Agent J, calling him "Agent G." She then later in her speech calls him by his name correctly.
Other mistake: You don't have to look further than the name; the title of the series is "Knight's and Magic" instead of "Knights and Magic".
Factual error: Two women come into town somewhere around San Luis Valley, Colorado with ring-necked Pheasants. The pheasants were brought into US a few times (East coast, CA) but really did not get established until late 1880s and in Colorado likely in the late 1890s (eastern and southwestern). The problem is it supposedly depicts the year 1880. They would more likely may have found some Gunnisons Sage-Grouse nearby or rabbits. (00:16:10)
Episode #1.2 - S1-E2
Factual error: The settlers prepare to burn Verity at the stake as a witch. Witches were never burned in England or her colonies; they were hanged.
Audio problem: Right after Carol finishes studying by singing a rap to Katie, Katie congratulates her and Carol hurries out. They exchange several lines of dialogue, but it all appears to be dubbed. During most of the dialogue, each character's mouth is not shown when they speak. However, the cadence of Katie's moving jaw can still be seen from behind, and appears to last longer than the audible speech. Additionally, Katie and Carol can each be heard to speak when it can be glimpsed that their mouths are not moving.
Continuity mistake: When Josh is asking his dad if the cops were hot, from the side he's leaning forwards with both elbows on his knees, then from the front he's more upright with one hand on his knee, arm bent out to the side. (00:09:45)
Continuity mistake: Celeste and Madeline are in the car and greet Bonnie, who's hiking. In the immediate shot of the copilot mirror's reflection Bonnie is nowhere to be seen.
Continuity mistake: As Rey tells BB-8 that he can stay with her, you see the droid behind her from a frontal view. When it cuts to a side angle of BB-8, the lines and details on the side of it's head close to it's "eye" change with more lines appearing, the orange rectangles at the bottom become taller, and the white rectangle box moves higher up. Also in the side view there is some black cone sticking out of what would be BB-8's "face." If it's his eye it's now suddenly sticking out way too far and isn't that extended. If it's the little censor thing that is next to his eye then it's now on the wrong side of his head. (00:00:25)
Episode #1.3 - S1-E3
Factual error: Billy is called up into a specific unit of the Royal Artillery. This didn't happen. He would first have been sent to a Royal Artillery training depot and only after training would he have been assigned to a unit.
