Continuity mistake: When Evan is out with Doug it is day time. Evan proceeds to get out his cell phone to text Casey. Then we see Casey and it's nighttime. (00:11:50)
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.
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)
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: When Dr. Andrews tells Mrs. Cross via video chat that her husband has blood in his NG tube, the clock in the top left corner of Mrs. Cross' phone says 5:09. Two shots later, it has suddenly changed to 5:01. A few moments later it changes to 5:10, then back to 5:01 and then for some reason to 4:53 at the end of the scene.
The Gang Tries to Serve a Subpoena - S4-E2
Continuity mistake: Luca and party are about to board a green private jet. Moments later when they take off, the shot shows the forward underside of a white plane. At first I thought that maybe it was white on the underside, but the nose wheel well doors are indeed green, and the takeoff picture shows an airplane with white nose wheel doors. (00:19:40)
Factual error: DI Renton is a Metropolitan Police officer 'parachuted' into Kent to solve a big case. This hasn't happened for many decades. Local police forces investigate their own crimes without help from the Met.
Episode #1.1 - S1-E1
Continuity mistake: The protagonist finally receives the Anmitsu, breaking his orgasmic trepidation. In the close-up, the tray is really close to the teacup, but in the following shot it's definitely further away, to the point that Kantaro in facts moves it to the right, in the same position shown in the close-up. (00:12:15)
Other mistake: There is a countdown on the movie screen. It is then reflected in Dusty's glasses. But the numbers are not reversed in the glasses. (00:41:00)
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.
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
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.
Factual error: Every Time the Shadow Raiders deploy to Somalia, they use a Blackhawk nicknamed "Adele" for their missions. I can understand the helos being transported via fixed-wing aircraft, but on their last mission they leave Georgia, and reach Somalia the same day, flying in the Blackhawks. It would take them some 15-20 hours not including fuel stops. Yet the mission is completed in the time it takes to find a bomb in downtown Atlanta.
Other mistake: The kids are viewing the VHS tape...but somehow the tape ends up in the old Hispanic woman's house...who then shoots it.
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.
Other mistake: The sign behind James Franco on the mirror behind the bar says, "Dinner Service Until 10pm". It's a modern paper printout and also a modern font, from a personal computer / printer which nobody would have at that time. (00:07:00 - 00:08:00)
Visible crew/equipment: When Adrian is getting something from the snack machine, the cameraman can be seen in the snack machine's reflection. (00:26:30)
Episode #1.3 - S1-E3
Audio problem: Elaine refers to someone's "ChatsApp" account, but her lip movements show she is actually saying "WhatsApp." (00:13:55)
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.
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.
