Factual error: The present day "Grimsby" train station shows electric wires and trains. The real Grimsby only has diesel ones.
Revealing mistake: Towards the end of the movie, the principal puts on his hat which turns his hair green. But you can see the green paint has already been applied before he puts his hat on.
Factual error: Jackie is handling medication vials and taking a pill. Some of the vials have childproof "palm and twist" caps, but they were not invented until 1967. (00:48:00 - 00:49:00)
Continuity mistake: The chef at the airport stabs someone, but the knife blade is clean afterwards; moments later he stabs it through the valise, and it is covered in blood.
Factual error: A bullhorn can be heard in the background off-screen during a battle with the zombies, even though the movie takes place during Victorian times. (01:19:30)
Continuity mistake: While Jax is held against the wall by two of the Furies it shows her bare feet held off the ground. As she moves across to Sinbad after he plunges the sword into the third Fury she is wearing flip-flops. (00:29:17 - 00:29:54)
Factual error: When Chiron is speaking with the social worker after being assaulted by Kevin, the social worker urges Chiron to press charges. It is the government who decides to press charges, based on evidence gathered by the police, including witness and victim statements. Crime victims do not decide whether or not to press charges. (01:02:20)
Suggested correction: It should be noted the term "press charges" in this case is meant to denote that a victim of a crime reports the crime to the police (as in file a charge against a person to the police), not the legal sense of pressing charges in court. Plus, victims of crimes can pursue a civil case against a criminal.
Character mistake: In the newsreel during the growing tensions, a newspaper headline featured with great importance goes like this; "ABUCTED son not yet found." (00:04:30)
Revealing mistake: In the opening scenes, we see a very pregnant Draka reclining on a bed of animal hides as Durotan watches over her. In the extreme closeup, we see Draka twitch her lips, and her small tusks flex from side-to-side with her lips, instead of remaining firmly aligned with her jaw as they should.
Continuity mistake: When Michelle gets catapulted onto the wall and begins wailing, her right arm is straight, semi-parallel to her shoulders. Next shot and it is bent, hand up to the level of her face. (00:22:55)
Continuity mistake: When Lady Susan is counseling her daughter Frederica in her bedroom, the shot shows an unlit candle on a dresser behind Lady Susan. The shot changes back and forth between Frederica and Lady Susan. When the shot changes back to Lady Susan, the unlit candle is gone, though there is no one else in the room.
Continuity mistake: When Chaz leaves the house telling Jesse that she has just 2 weeks to pack, in the close-up when she says "Bye..." her hair is all in front of her shoulders as opposed to the rest of the scene. (00:08:40)
Continuity mistake: The protagonist is fondling his pregnant wife in bed when she pinches his nose. Between the two shots the blanket covers /uncovers the baby bump, and her hair is bunched on the pillow in entirely different ways. (00:01:40)
Factual error: Viggo is "playing" the bagpipes on the wrong side. They should be under his left arm, not his right. He is also not blowing hard enough to make the required sound. They sound good, though.
Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
Continuity mistake: The sun angle changes several times during the chase sequence when the dragon is on the flatbed truck.
Continuity mistake: When Kurt and Kavi are washing clothes, the clothes change position on the line, specifically the red shirt at the end and the shorts Kavi hangs up. The red shirt is twisted around the line, but in the shot of Kavi hanging the shorts, the shirt is hanging perfectly straight down.
Factual error: During the scene when Ed the I.T. guy is working on his laptop to fix the problem with the presentation, his laptop is sitting on top of a couple of Cisco network switches with cables connected to them. The ports on the front of the switch where the cables are plugged in would have flashing lights on to show power and connectivity, as well as lights on the left-hand side of the device as we are looking at it, no lights are present which suggests it is not powered up and connected to anything. (00:06:58)
Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Audio problem: In the final conversation between Limus and Bardot, the robotic effect usually applied to her voice is missing.
