Keanu Reeves gifted each stunt worker with a personalized t-shirt detailing how many times that performer met their demise in the film. His five-person stunt team also received Rolex Submariner watches, each costing around $10,000, with a personalized message on the back of each one when filming wrapped.

The Paris subway station where John Wick meets the Bowery King and Winston is "Porte des Lilas." It's often seen in films, as this particular station has a disused platform that's still kept fully functional, so it can be rented to filmmakers who wish to shoot in the Paris subway without having to disrupt regular traffic.

The scene at the beginning of the film in the desert was done without digital enhancement. The place where John Wick meets the Elder is an actual rock where Lawrence of Arabia (1962) was filmed.

Lance Reddick's final completed film role before his tragic passing on March 17, 2023, just one week before the film's release. This is not set to be his final appearance as the character, as he is confirmed to have filmed scenes for the Ballerina (2025) spin-off. At the premiere, Keanu Reeves and other stars of the film wore blue ribbons to honor the late Reddick. The filmmakers have confirmed that a dedication card to Reddick is to be added to the end of the credits.

John Wick says only 380 words throughout the film. Almost a third of Wick's dialogue consists of just one word like, "Yeah." Chad Stahelski revealed that Wick doesn't have a lot of dialogue because "Mr. Reeves stripped out roughly half the dialogue written for his character in the initial script." The longest line of dialogue that Wick has is in a scene with Shimazu Koji where he says, "You and I left a good life behind a long time ago, my friend."

Continuity

Throughout the entire car chase scene in Paris, John car hits multiple other vehicles and people. Yet, except for the missing doors and windshield, there's not a single dent anywhere on the car.

When John is thrown into a Mercedes minivan during the Arc de Triomphe shootout, the driver is never shown leaving the minivan. But in the next shot, no one is inside. Also, the lights were on when John was thrown, but in the next camera shot, the lights were off.

During his night fight in Paris, John never reloads his 9mm Viper pistol despite firing more bullets than the 21 round magazine can hold.

When John is fighting the Tracker on his way to the duel, sunlight is streaming through the building windows (in which they are fighting). Yet when he busts through a window and falls to the street, it is still completely dark out.

When John is running around Paris the night before he meets The Marquis for the duel, he enters a closed building, which just happens to have all its lights off, and its front doors unlocked. He then is seen busting open one set of double doors. The bad guys that follow him have to again bust open BOTH sets of doors, of which at least the second interior French style doors would still be open from John's passing.



Factual errors

Japanese train, lights never go down even while running and also the seat is made of fabric instead of plastic.

Dragon's breath rounds can't be used in semiautomatic shotguns, due to not producing enough recoil to cycle the action, and don't light people on fire nearly as easily as they do.

Killa's night club in Berlin appears to be some multi-story Greek temple. It?s actually the Alte Nationalgalerie on Museum Island which hosts several pieces of priceless German art and definitely does not have torches and a three story indoor rain fountain.

When John Wick requests being readmitted to the Ruska Roma with Katia, the on-screen subtitles misspell 'duel' as 'dual'.

The Paris street map in the Continentals' control room on which they track John Wick shows Sacr? Coeur at the location of Op?ra Garnier, about 3km south and west of its actual location.



Incorrectly regarded as goofs

"The Paris Continental's radio station has the call sign "WUXIA". The use of lettered "W-" or "K-" call signs on commercial radio is a uniquely American thing; a French radio station would instead identify itself by its formal name or a radio frequency. They also generally only have four letters." However, the call sign is a homage to Wuxia, a genre of Chinese fiction involving martial artists in ancient times.



Revealing mistakes

The Arc de Triomphe is missing the eternal flame which crowns France's Tomb of the Unknown Soldier. As its name suggests, it is never ever allowed to go out.

Typical Hollywood action movie henchmen "waiting" for their turn to be hit by Wick, instead of going all at once.

If you pause the video just right when Mr. Nobody discards his card during the poker game, you can see he tossed the ten of diamonds. But his royal flush is in diamonds.

In one scene, you can see the skyline of New York from Queens, and everything is proper except One World Trade Center, which is between the Empire State Building and the Chrysler Building, as well as the Citigroup Center, when One World Trade is miles south in southern New York City.

Obvious retractable blades when the female fighter stabs the henchman's back with her knives (they move around while she tries to hold still on his back).



Miscellaneous

Even though there is a prolonged gun battle through the streets of Paris, not a single police officer is seen or siren is heard to respond to the chaos.

In the opening scene, after galloping through the desert on horseback and shooting The Elder, John Wick, wearing a black suit, shows not one drop of perspiration.



Anachronisms

The presenter of the Parisian continental radio station should be presenting in French, seeing as the listeners are all French.



Plot holes

During both the club and Arc de Triomphe scenes, civilian dancers/drivers clearly see the violence, including multiple people being shot and killed, yet continue to go on normally.

When Caine meets John at the stairs, he asks " how long until sunrise?" John says "Two minutes. Maybe three." The fight up the remainder of the stairs takes over four and a half minutes. The sun was late for work that day.



Character error

When his contract was increased to 20 million USD, the German female accountant says "John Wick, vertraglicher Anstieg auf zwanzig (20) Milliarden Dollar", meaning 20 billion USD, with a B.

When the Tracker checks in to the Osaka Continental with his dog, Tracker refers to himself as being HER emotional support animal, implying the dog is a female. But when the dog pees on Chidi after Tracker kills him, the dog lifts a hind leg the way a MALE dog pees. A female dog would have squatted.

Wick has the greatest difficulty killing the horseback riders when aiming properly but then suddenly kills the second one (who is in front of him on his left) without even aiming and with his right hand behind the horse's head (his gun was pointing right less than a second prior in the previous shot).
