Continuity mistake: (Episode 4: Lonely hearts) The woman's body changes position after being hit by the car in the beginning. As the body stops tumbling after the hit, she ends up laying next to the bridge railing, along side it, in the next shot her body lays in the middle of the driving lane, feet toward the mid-line and head towards the railing.
Character mistake: When Nick and Hank talk about going through the park, Hank says "come on, David." David is Nick's real name.
Tarantella - S1-E11
Character mistake: Hank's action as a cop towards the man on the boat makes no sense when going after Lena. He has to think the man he grabs is a potential victim. Obviously, he wants to keep him quiet, but there's no reason for Hank to hold his gun against an innocent man with his finger on (or near) the trigger.
Factual error: It is stated that is Mannheim, Germany but the picture is of the Market Church in Hannover, Germany. (00:25:25)
Continuity mistake: When Juliette comes back from being in a coma, it is made to seem like they only have 1 bedroom upstairs as Nick stays on the sofa for a while before moving in with Monroe. However, later in the series, when Trubel comes in, she stays in their guest bedroom.
Other mistake: It is right after dinner when Angelina and Nick leave for the bar, but when they get there it's daytime.
Factual error: Rosalee shows an old letter allowing her to contact the "Wesen Council" ; the letter is that of a law firm (Advocatenkantoor) in Amsterdam and the Hague. On the top of the letter instead of the correct inscription "Den Haag" we find "DeHaag" which is incorrect. (00:33:20)
Factual error: The assassin sent to kill Captain Renard carries a French passport which lists his place of birth as "Marseilles". This is an old-fashioned spelling of the name now almost only seen in North America. The French spelling is and always has been "Marseille".
Goodnight, Sweet Grimm - S2-E22
Factual error: There is a copy of a Czech passport shown when Renard reads the files sent from Paris. There is a typo in the place of birth which reads "Brastilava" instead of "Bratislava" (capital of Slovakia). Interestingly enough the name of the city is also spelt correctly on the passport just below, where it refers to the place of issue. (00:06:45)
Twelve Days of Krampus - S3-E8
Visible crew/equipment: During a fight scene between Nick and the Krampus you can see a man running out of the shot. This is the part of the fight just after the kids are being lowered from the tree.
Other mistake: In the final scene Hank walks away in the opposite direction to the exit and walks around a corner that goes nowhere. This is confirmed from an earlier scene when the thugs broke in to the apartment and they enter the hallway from the opposite end. (00:42:00)
Factual error: Frankie's official military record shows her rank and grade as Specialist E-3. E-3 is a Private First Class. A Specialist is E-4.
Thanks for the Memories - S4-E1
Factual error: Sean Renard is seen going into 'asystole' at The End of the episode (flat lining) and the doctors use a defibrillator to shock his heart, but a defibrillator is useless with asystole. It is only used to correct abnormal heart rhythms (fibrillation). Defib-ing an asystolic heart is like trying to reboot a computer device with no power supply.
Character mistake: Raymond refers to his equipment as EMF (Electromagnetic Fields), except it is labelled as EMR (Electromagnetic Radiation).
Continuity mistake: When the woman falls near the beginning, her arms are out to her side, almost making a T shape, even after she stops moving. In the next shot, her arms are down by her side.
Continuity mistake: When the couple is in the boat when the creature appears, the woman is taking a picture and holding her phone in her left hand, she turns around and her left hand is raised and her right hand is on the boat edge. When the camera angle changes, her left hand is now on the boat and her right hand is lowered and holding the phone (confirmed when the camera angle changes again and she's in the same position, holding the phone in her right hand).
Map of the Seven Knights - S5-E10
Factual error: The Czech crime database (which appears to be an official Czech database) is headed 'Czechoslovakia'. Czechoslovakia has not existed since the Czech Republic and Slovakia separated in 1993 and neither country uses the term any more.
Continuity mistake: When Marwan Hanano stops the basketball with his foot, his feet are facing the court, so his left foot is almost perpendicular to the concrete strip. In the next shot, with his right foot still on the ball, his left foot changes position, so it's nearly parallel with the concrete strip.
Continuity mistake: When Monroe plays back the video of Wu, Wu tilts his head over after he drops his hand. However, in the original scene Wu never moves his head. (00:36:35 - 00:37:55)
Continuity mistake: When Nick goes to see Juliette/Eve, she's in a coma and unable to move and her hand and fingers are lying flat against her belly. In the wide shot of her, her hand is turned and her fingers are somewhat on top of each other, instead of lying flat. It goes back to lying flat in the next shot of her.
