Continuity mistake: At the beginning of the movie, the hunter is looking for his dog. The rifle on his shoulder keeps changing position, being upside down or not - which is easy to spot because of the big scope. (00:01:30)
Factual error: The film is set in 1880 and Dan Leno is a major character, already well-established on the London stage. Leno was only 20 in 1880 and did not make his London professional debut as an adult performer until 1885; before then he had performed in Manchester and Sheffield.
Factual error: The presidents of South Africa, South West Africa and the Rhodesias all object to Seretse and Ruth's marriage. But the head of state of all these countries and territories at the time was King George VI. None of them had presidents.
Factual error: The jacket blurb and plot synopsis for "Anthropoid" are historically and factually incorrect in stating that Heydrich was "third in command" of Nazi Germany. He was not; there was a chain of Nazi hierarchy above him and any historian of Nazi Germany will verify that. Unfortunately, Rotten Tomatoes perpetuates this inaccuracy by using the same jacket blurb in its own plot summary of the movie.
Factual error: In the wedding and arrest scene the U.S. Customs Service officials have police attack dogs. The U.S. Customs Service only has drug detection dogs. (01:57:00)
Continuity mistake: The gang Bo is reluctantly part of gets to Maurice's crib where he is playing cards with his homies. The red jacketed one is defiant, and grabs a handful of red and blue chips in front of him tossing them in Angelo's face. But if you check out of the table in the wide shots before this occurs, you'll notice that red chips were never in the stack in front of him to begin with. (00:19:05)
Continuity mistake: When Gina and James visit her sister, Gina sits down at the table with the family. Then in a close up with James and Ramon, Gina walks into the same room she should already be sitting in. (00:48:30)
Continuity mistake: At the end, when Gloria hurls Oscar completely out of sight beyond the horizon, a huge crowd of South Koreans rush up directly behind Gloria, cheering and applauding, only a few feet away from her. The camera cuts to a frontal shot of Gloria, and now the crowd is 30 feet or more in the background.
Revealing mistake: Despite Sigourney Weaver supposedly having had her fingers cut off if you watch her when she's in her straitjacket you can see her fingers moving around.
Factual error: The 5th Amendment to the Constitution simply states that "No person... shall be compelled in any criminal case to be a witness against himself." There is no actual or implied provision that means once you have answered a question, you can't plead the 5th on any subsequent questions, as the movie depicts.
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)
Continuity mistake: After the credits, Tom Hopper sees and hears a bunch of helicopters and calmly walks indoors. He then addresses the waiter raising his left hand before the cut. In the next wide shot though we see him with a right hand raised that reaches for the champagne tray and grabs a glass. He says "Thank you" in a third shot, same angle as the first one, and in fact, the champagne flute is in his left hand now. (00:02:50)
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.
Other mistake: When Bill is alone with the girl at his house, there is a roaring fire, but in the next scene the fire is completely out and he comments, "you must be cold, I didn't have time to start a fire".
Audio problem: The chef finally gets the bright idea to fire his hunting rifle at Morgan's fleeing vehicle. In a previous scene he was grabbing ammunition for his rifle, and he also loaded it. The rounds appeared to be high power rifle ammo, probably in the 7mm Remington magnum or .30-06 range, very common hunting rounds. When he fires his rifle it sounds quieter than a suppressed shot, however he has no suppressor on the muzzle end of his weapon. (01:09:20)
Continuity mistake: The old man in the hotel lobby pulls the flowers out of the megaphone and calls the protagonist. She lowers the headset to talk to him. The left speaker is all the way across the opposite side of the neck in the first shot, less shifted to that side in close-up. (00:04:00)
Continuity mistake: Walter tore out the newspaper article ("Body of Woman Found at Greenland Rest Stop") fairly neatly/evenly; it was relatively straight across the top, though a little jagged as could be expected. When Walter looked at the article some time later, the jagged top was worse and there was MORE space between it and the title. The right side also appeared to be more jagged than it was and include a little more of the article that was to its right before being torn off. (00:07:03 - 00:13:37)
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.
