The Jaguar at the beginning of the movie is OU16 LVA. The 16 on UK number plates means the car was registered between March 2016 and end of August 2016. Shortly after, the movie moves to two years later which at the time of writing is the future assuming the film is set in present day.
If no other dates are referenced, there is no reason why the film must be set on the day it is made, or released ; but if the 16 is valid, then the later scenes would have some UK number plates with 18, 68 etc.
When Michael Bryce is preparing to pick the lock of the Mercedes, his pick kit has tools used on house-type locks. "Wigglers," used to pick automotive locks, are not in his kit. If the character is adept at lock picking, he should know his picks aren't the right type.
During the climax fight scene featuring the helicopter, the henchman can be seen firing an H&K G36 from the exterior but when the camera switches to interior, he's shooting the compact variant (H&K G36c) instead. This happens multiple times over the course of four cuts.

There is no conceivable route from Manchester to any part of continental Europe that passes through Coventry. You would either fly out of Manchester (or a local field) meaning you're ~100 miles from Coventry or drive to a sea port on the South or East coast entirely via the motorway network. In the latter case you might pass a few miles from Coventry on the M6 if heading to the East coast but wouldn't come off for any reason.
Before Michael and Darius get dropped off at the Dover-Amsterdam ferry by the van full of nuns, out of the window in the background you can see the NEMO Science Museum, which is actually in Amsterdam, not in Dover. The van is clearly driving through Amsterdam, but after they get dropped off the movie continues like they just took the ferry from Dover to Amsterdam.
When Professor Asimov testified at the trial that Dukhovich killed his wife and child, Dukhovich's attorney objected that this was hearsay and the court granted the objection and excluded the testimony. The testimony was not hearsay. Hearsay is testifying about what someone else said happened. Asimov was testifying about events that he directly witnessed and the testimony should have been allowed.
Contrary to the way it is frequently portrayed in popular culture, Interpol is not a supranational law enforcement agency and has no agents who are able to make arrests. Instead, it is an international organization that functions as a network of criminal law enforcement agencies from different countries. The organization thus functions as an administrative liaison among the law enforcement agencies of the member countries, providing communications and database assistance, assisted via the central headquarters.
Car airbags all have two large (approx 5cm/2") holes in the back so the airbag deflates almost immediately after a crash. This is why airbags ALWAYS appear deflated in wrecked cars, so there was no need to shoot holes in the airbags, and indeed the bags would already have been mostly deflated by the time Samuel Jackson shot holes in them.
During the trial scene, Samuel Jackson's character requests that a court employee access an FTP site to show some evidence. The employee accesses the server and displays some images. FTP servers are like file cabinets and do not display documents, only store them.
When Salma Hayek's character, Sonia, is being questioned in her cell. She is sitting lotus position in the chair, left on top of right leg. In a different camera angle her legs are crossed the opposite direction.
When he first appears, Kincaid is shown in leg irons in Manchester. Leg irons are illegal throughout Europe and are not used. Officially.
However, being illegal doesn't means they aren't used, unofficially. Kincaid's wife was being held for no lawful reason, and was going to be released in return for his cooperation ; further examples of illegal practice.
The Netherlands' emergency services and police vehicle striping is not correct. The striping is red and blue not with blocks. Policelogo is not correct and the police uniforms are different. Also the Locations in the Netherlands are filmed in Bulgaria or somewhere in east Europe. They photo-shop it terrible. On Location they use wrong traffic-signs ,posters and advertising.
