At the end of the movie, when Skarssen is killed on the roof in Istanbul, the sun is high in the sky, visible by the shadows. After Skarssen's killer walks away, the sun has almost set behind the buildings.
When Detective Ward is shot in the neck at the museum, Salinger tries to stop the gushing blood with his hand. Yet, when he grabs the (white) railing as the shoot-out continues, he leaves no traces from his blood covered hands.
The characters Tommy and Clement are talking inside of an Audi. But when Louis finds out that Clement died, the car shown in the picture online is clearly a VW Passat.
When Salinger finds the black car The Contractor used to run over Elle, the first shot shows an unharmed windshield, and seconds later they show it has the mark seen after the crash.
When Eleanor meets Salinger in Italy to visit Calvino together, her driver is seen just off screen unloading her luggage from the back of the car. In the next shot he gets in the car, there is no luggage, while Eleanor, Salinger and the Italian inspector just walk away, no luggage in hand.
When a man is shooting with a sniper rifle at the shooting range you can first hear the shoot and after that you can see the impact on the target. This is not possible, because the bullet is flying with supersonic. Therefore you should hear the sound of the shoot after the impact of the bullet.
When Salinger looks through the bullet holes in the pillar back toward the hotel, each hole lines directly up with the location of the shooter. This would not be possible from that distance, because the shooter would need to aim up to account for bullet drop, meaning the holes in the pillar would point well above the origin of the bullet.
The police enforcement in Luxembourg are not referred to as the Gendarmes. They are known as the Police Grand Ducale.
Eleanor says that the both of the bullet casings from the sniper's rifle in the room match forensically, but this is impossible. Like the rifling creates an impression on the actual bullet, the chamber, bolt and receiver all leave distinct marks on the casing and they cannot be copied. Furthermore, factory rifles often differ significantly with respect to headspace. All such small differences are measurable.
It would be obvious to a skilled forensic analyst that the case had been fired from a different rifle.

When Salinger and Karssen meet on the Grand Bazaar rooftop in Istanbul, both characters are backlit, even though they are facing each other. (According to the DVD commentary, the director wanted both to be lit by a dramatic back light. The scene was filmed twice, once in the morning and once in the evening. After cutting between the two shoots, the sun is behind both actors in the scene.)
During the shootout in the Rotunda, an Uzi SMG is on full-auto yet sounds like a semi-automatic pistol.
When Salinger is talking to Dr. Isaacson you see a camera moving in the background.
In the final scene, a close-up of Salinger's eyes shows a white rectangular reflector.
Ahmet Sunay meets Jonas Skarssen in Istanbul. They begin their discussion outside the Suleymaniye Mosque, then enter the Blue Mosque. When Sunay and Skarssen move to a more private place, Sunay leads him underground, to the Basilica Cistern. After the two leave the mosque, they move to the Grand Bazaar in just a second. The 4 places are all within a few kilometers of each other, but are not connected in the way the movie portrays.
The building of Calvini Defense HQ at the Lago Iseo, Italy, is actually the "phaeno", a science museum designed by Zaha Hadid in Wolfsburg, Germany, which is located in the center of the city.
The VW Tiguan Eleanor drives in New York City is clearly a European version, with no amber or red side markers, and a rear cut-out for a wider European license plate.
When Eleanor is exiting the taxi, a boom mic is clearly visible in the car window.
