Factual error: When Jake Gyllenhaal confronts one of the suspects in the shed and wakes up (several hours later) after being knocked out cold, he moves the dead guy's arm. Normally, bodies stiffen up after being dead for several hours, but when Tony (Jake) moves the other guy's arm, it is not stiff at all.
Continuity mistake: Gina arrives looking for first aid supplies. She has bruises on her arm. However the next day all the bruises have gone. (00:11:30)
Continuity mistake: Blood from Tom's shirt's elbow when he is attacked by Rachel appears and disappears randomly between shots.
Continuity mistake: When Laina has to take off her clothes to change after she failed, there are no straps, meaning no bra. When she and Blake are changing by the pool, she has a bra on. She never had time to change/find one.
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)
Revealing mistake: When the Creature is telling Louis the "Bat Story," the Creature is holding a burning torch in its right hand against a wholly-dark background. It becomes apparent that the shots of the creature are actually Dutch Angle shots (the angle of the camera is rotated about 45°), because the smoke from the torch is not rising straight upwards; rather, the smoke is rising at a 45° angle toward the upper left corner of the screen.
Factual error: The movie puts a caption in the prologue "January 2013." Later the protagonist puts the hammer he received by the mysterious delivery right on top of a newspaper, a copy of "Mid-Day" with a retouched opening article (related to the movie murder of course) but headline news with a Sunil Gavaskar quote that dates it as a December 2015 edition. (00:03:20 - 00:10:10)
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.
Continuity mistake: Mikey dropped the wristwatch Andrew gave him and it landed face down with the bands upward. When Mikey jumped off the rock to retrieve it, the watch's face was on its side (visible to the screen) and the bands were parallel to the ground. (00:05:04)
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.
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)
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.
Continuity mistake: John Biswas is tailing the little deaf girl. His scooter breaks down and he follows her on foot. They are walking in the same road in two different shots, with a cut just a few meters apart. The toys in her right hand and the paper in her left swap hands in the second shot. (00:18:20)
Continuity mistake: The main character is chatting with Harper at the shooting range. Harper's earbuds and protective goggles change position between shots throughout the scene. (00:08:50)
Continuity mistake: In a second view at a different angle of the bank employee being shot, one of the doors that was shattered in the original shot is not shattered in the second shot. (00:03:02)
Continuity mistake: Throughout the movie, fire axes seem to be the weapons of choice. Only two fire axes are used, but they appear recurrently. In the very first use, the protagonists grab fire axes to butcher the monster called Beverly. Blood and gore go everywhere; yet, the axes emerge from this bloodbath with no blood or gore on the handles - they're virtually pristine moments later. The axes are used again and again, right up to the ending, and blood comes and goes from the axe handles seemingly at random.
Revealing mistake: When Gabby and Fin are hanging off the building in Las Vegas, you can see that Gabby isn't holding on to anything in some close-up shots. (00:11:47)
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: Many details are wrong in Elizabeth's execution. The scaffold is in the prison yard, whereas by this time it was inside. The noose has a knot as opposed to the simple slider which was used by this time. Nobody is present except the hangman and one warder, whereas in fact the usual execution party was the prison governor, the chaplain, at least two warders, the hangman and his assistant. The hangman is masked, which never happened in Britain.
