Although commonly shown in movies to do so - as here (twice) in the airport scene - handheld tasers do not knock people out.
In the movie, car plates start with letters in scenes showing Antalya, Turkey. However, in Turkey, all car plates start with numbers that are assigned alphabetically to the cities, so Antalya plates start with 07.

Orson insults Mike by calling him a "spineless jellyfish". Clearly redundant, as jellyfish are all spineless.
No blood is spilling from the stab wounds to the neck of two henchmen.
The "dead pilot" gracefully falls on the ground when being pulled out of the helicopter revealing that the stunt helped his fall.
In the opening scene, the soldier/security about to be killed by a knife to his throat does not try remotely to defend himself by grabbing the hand that is gagging him for a full second before the fatal blow.
Orson connects his gas canister to the external compressor of the air conditioned. This would not cause the gas to be vented into the interior of the property as it's part of the closed coolant loop. All it would do is break the AC.
The tail number of the chopper in the climax is "N" -- which is the United States. The scene is supposedly set it Turkey.
"Burbank L.A., USA" is not a place. Burbank and Los Angeles are two separate, distinct cities.
When they arrive in Madrid, the opening interior image is in the Lisbon Airport. One of the electronic commercial panels can read "Welcome to Lisbon". A sign of directions has written in Portuguese "Recolha de Bagagem" (Baggage reclaim). And there's the Portuguese shop "Made of Portugal" in the right.
Sarah was driving in the Car when being followed by Franks man. Then in the helicopter she was in some rooms even though Orson didn't lift Off yet. But then she reappeared with the Rest of the Crew.
Fidel can detail the "crocodile skin" case of the target but fails to see two colleagues being assaulted and an obvious loop or glitch on her feed.
The arms dealer doesn't bother having his room checked for bugs after having hosting a party, whether or not his gullible lawyer told him about the female visitor.
