Blooper

(at around 2 mins) At the end of John Wick - Capitolo 2 (2017) when Winston gives the excomunicado order it is 4 pm on his watch and he says John Wick has one hour. In Part 3, he becomes excomunicado effective 6 pm, which is two hours from 4 pm.

(at around 1h 24 mins) When John Wick meets Winston in the glass structure after being sent to kill him, several shots in which John is not in focus appear to have his ring finger in place. It's only when his hand comes in focus, do we see the ring finger has been cut.

(at around 37 mins) The M1911 that The Adjudicator recovered in this film is a different colour to the one the Bowery King gave John Wick in John Wick - Capitolo 2 (2017). The Kimber M1911 shown by the adjudicator is a full black M1911 while the one used by John Wick to kill Santino D'Antonio was a dual-tone M1911.

(at around 4 mins) When John and his dog get in the yellow cab it is pouring with rain and both are soaking wet. When they are in the cab the dog is completely dry.

(at around 8 mins) During the library fight with Ernest, John is holding a book and using it as a weapon. When Ernest grabs John's head before shushing him, John can be seen dropping the book. In the next shot the book is back in his hand.

(at around 14 mins) There is no way to fix a nicked artery in such a way that it will not tear open again if you get into extended hand-to-hand combat right after the surgery.

(at around 34 mins) It is not possible to determine the exact caliber and round just from looking at an entry wound.

At Casablanca shootout, both John and Sofia fire far more shots that a pistol magazine holds and furthermore - at several instances Sofia changes the magazine and starts shooting immediately i.e. without chambering a round.

(at around 16 mins) You cannot mix and match parts from different vintage revolvers, let alone expect them to work. While weapons such as these in fact were among the earliest mass produced items that kicked off industrial series production and brought about the standardization of parts, in items from these early stages, you'd be lucky if even just the screws from the one fit into another.

(at around 58 mins) During the Morocco Continental fight scene Sofia fires her pistol six times then removes the magazine to check it before putting it back in. She then fires her weapon a further seventeen times before reloading, making twenty three shots from one magazine. After reloading she then goes on to fire the pistol over forty more times without reloading again. The Kel-Tec PMR-30 is reputed to have the highest capacity of any handgun at 30 rounds yet Sofia easily bests this by over ten rounds.

(at around 1h 35 mins) When John Wick walks out of Winston's safe room gun safe with the shotgun and armor-piercing shells, it may appear there is a red shotgun shell jammed in the ejection port; there is not. His Benelli M2 TTI Taran Tactical shotgun is equipped with two MatchSaverz Shotshell Holders which are commercially available. One holds an extra round directly in front of the ejection port on the right and another on the left side for immediate access of extra rounds without reaching into an ammo pouch or pocket.

(at around 1h 40 mins) When John and his assassin are fighting underwater in the pool using automatic weapons, both are only good for one round. The water resistance prevents both weapons firing automatically. Instead when the triggers are pulled, only one round each are spent. After that the weapons would have to be cycled as semi-automatics.

(at around 58 mins) When Sofia and John are escaping after shooting Berrada you can just see 2 dogs running through the catacombs while under fire. But Berrada shot one of the dogs earlier.

After Berrada shoots the dog, Sofia shows that the bullet mushroomed when it hit the dogs bulletproof vest, thus it was not hurt.

(at around 1h 29 mins) When Winston enters the safe with John and Charon, he put his hand on a fingerprint recognition device. However, the hand-prints shown on the device doesn't match with his hand setting.

(at around 1h 30 mins) The c64 used to deconsecrate the Continental has no power. The power cable of a c64 is plugged into the right side of the case, next to the power button and two joystick ports. Yet there is no cable plugged in at all.

(at around 1h) The exterior stairway in the courtyard where the main fight scene takes place does not have proper steps but is simply an incline with slats where the steps should be. This makes it easier for a dog to go up and down at high speed.

(at around 46 mins) In the Japanese Sushi Bar on the bridge scene, chopsticks are set on the wrong direction. They are set up in principle for right handed guests.

The car damage in the Cab garage changes when he pulls into his home garage! When Aurelio shows up the damage reverts back to the original damage.

(at around 1h 9 mins) The Adjudicator sentences The Bowery King to "seven cuts," but Zero only cuts him six times.

(at around 23 mins) During the motorcycle chase under the elevated train, all parked cars have their headlights on.

(at around 1h 22 mins) When Wick is reunited with his dog, you can clearly see the peanut butter (or other substance) on his face to get the dog to lick him so much.

(at around 22 mins) In the horse stable fight sequence, you can see behind one of the horse stalls, a horse trainer pulling the reigns up and down to make the horse in the background rear on its hind legs.

(at around 23 mins) The scene in which John Wick fights off assassins near Chinatown in Lower Manhattan was shot entirely underneath an elevated subway line. There are no such lines in, or anywhere near, Lower Manhattan, and visible street signage indicates the scene was filmed in Bensonhurst, Brooklyn, a destination it would've taken Wick 25 minutes to reach via horseback at maximum speed instead of seconds.

(at around 37 mins) The Bowery King is clearly living in DUMBO. A neighborhood in Brooklyn directly across the water from Lower Manhattan. The Bowery is in Lower Manhattan and is 3rd Avenue below Houston St. When the Adjudicator tells The King to abdicate there is a clear shot of the purple F.D.R. Drive (which is located in Manhattan) behind her across the river from Brooklyn.

The Moroccan scenes were shot in Essaouira, not in Casablanca as the movie claims.

(at around 11 mins) Wick is shown running down Pell St. in Chinatown when visiting the doctor who sews up his stab wound. In the background of the doctor's office, numerous cars can be seen driving up and down the street in both directions. This would be impossible given that the area behind the buildings along Pell St. back up to Columbus Park, where no cars are permitted.

(at around 1h 18 mins) The motorcycle scene on the bridge starts at the archway entrance of the Manhattan Bridge but cuts to the lower level of the Verrazzano Bridge (which is located between Staten Island and Brooklyn).

(at around 14 mins) The Doctor asks Wick to shoot him twice to make it seem like his assistance was forced. However, in both instances he moves his shirt out of the way. Lack of a holes in the front of his shirt would be a giveaway his wounds were planned, aimed, and intentional.

At the end of the previous movie, Wick had been pursued by a number of independent assassins attempting to claim the bounty that had been placed on Wick. This was done while he was still in good standing with the Continental and all of its affiliates, and nobody had any qualms about attempting to kill Wick.

At the beginning of this movie, which begins immediately after the second leaves off, all of the independent assassins are obliged to wait until the official excommunicado order takes effect before attempting to kill Wick, despite having no necessity to do so beforehand.

(at around 1h 17 mins) When John arrives at Grand Central Station, he is met with opponents. They stab people, and walk around brandishing knives. Nobody in the general public reacts. Later, there is gun-play close to the public. Again, nobody reacts.

Since Charon knew about the incoming swarm's bullet-proof armor, he should have provide adequate weapons to all his guards who came out just to be slaughtered, and started off with the ammo used in the second round.

(at around 25 mins) At the Ruska Roma, a trained ballerina struggles to perform as the Sugar Plum Fairy. However, this is because she has been given the wrong music - not for the famous solo, but for "The Prince and the Sugar Plum Fairy", which is a series of duets.

(at around 1h 35 mins) Shotguns are not the ideal choice under the circumstances. You get the same armor penetration from any battle rifle while they are also much quicker and easier to reload because of the high capacity detachable box magazines.

(at around 8 mins) During the assault in the library, Wick's opponent despite having the clear height advantage, only actually uses one of his arms in the latter half of the fight with it trailing behind him perfectly healthily yet completely unused, this could be down to a lack of choreography in the fight behind the scenes.
