When Marie climbs out of the forklift, her pistol has a suppressor fitted to it, but it disappears as she shoots into the air.
When Mace first enters the subway, the platform is empty. In the next shot there are a number of people standing on it.
Khadijah can be seen dropping her shoes to the floor when she exits the ventilating system. In the next shot she can be seen standing up and stomping on her phone using her high-heeled shoes. This is a continuous shot and she is not seen putting her shoes on at any point.
In the first two minutes of the film, Elijah Clarke et al. arrive to meet with Santiago. He is watching a football/soccer match [presumably] on a wall-mounted TV hung between the two shade lamps above the console at his 1 o'clock. However, the next scene reveals there is no TV in the room whatsoever.
The aircraft to Shanghai looks like Lookheed C130s from the outside. Such aircraft have a cargo hold width of more than 3 m. The interior cabin shown is considerably narrower.
During the pier scene, Marie uses a JCB telehandler to gain access over the water onto the boat. She is seen 'flicking' the lever, then standing on a forked pallet which moves forward as the boom extends. This is impossible as all modern plant machinery, as seen in this scene, operates on a deadman switch basis. That is, once the switch or lever is released all operations immediately stop. This is for obvious safety reasons. An operator has to be in control at all times, and in most modern machines, someone has to be sitting in the seat as this activates a secondary switch that overrides and shuts down the whole system if the operator leaves the seat for any reason.
In one scene the Chinese police arrived in a Renault Mégane 3 hatchback police car. This model was never officially imported to China and impossible to be used as police vehicles.
The shot supposedly hitting the femoral artery - wrong location in the thigh; not enough bleeding.
As she leaves the fish market, Marie trades a couple of lines in French with a French counter-intelligence agent. The agent is played by English actor Joseph Wicks whose phonetically delivered line in French is barely intelligible. Amusingly, Diane Kruger who plays Marie is a German actress playing a German character but Kruger is fluent in French and her delivery of her French lines are near flawless.
The plane to Shanghai has 4 engines but only 3 propellers.
Mason and Nick eat Chinese takeaway from cardboard boxes as they plan their mission in Paris. While those boxes are staples of Chinese takeaway in the United States, they don't exist in France.
Khadijah says the drive is going "Southeast over the Atlantic". Southeast from Paris would go over the Mediterranean, not the Atlantic. She also tracks the drive to Morocco, but Morocco is not Southeast of Paris.
Marie steals the bag in the center of Paris and is chased after by Mace. Soon, she escapes using the subway system at The Porte des Lilas. This station is too far from the center. In fact, while there is a real station named Porte des Lilas, there also is a ghost station with the same name set up as a studio and for exclusive use of cinema.
In the Moroccan bazaar, they make a big deal of trying to figure out whether the courier handed off the drive. But they have a tracker on the drive so they could just follow that.
The gang are following a suspect in Morocco. He goes in to a men-only bath-house. They realize that neither of the white girls can follow him, so the black girl comes down from remote over-watch, changes her outfit, buys some soap to give her an excuse to enter the building, meets her team-mate outside, goes in to the building to follow the perpetrator, and he is still making his way down the same 20ft hallway.
Marie identifies herself as a DGSE agent to take custody of Graciela. The DGSE however is the French foreign intelligence service and only operates outside of France. The French counter-intelligence agency operating in France is the DGSI.
