Continuity mistake: The guy who greeted Ghazzi at the door escorts him and a group of men inside the club and to a table. As he is showing them their seats, he places his hand on the guy's shoulder to his left and nudges him to the table. It then cuts to a closer angle and suddenly he's facing the guy to his right again before he then rubs his nose and then places his hand on the guy's shoulder to his left again to nudge him forward.

Continuity mistake: After Ghazzi is embraced and greeted at the door, Valentina is watching from a side alleyway. She glances over at the red van where the FBI agents are watching and you see Witherspoon in the passenger seat. It then cuts to a close up and suddenly Witherspoon has his arm up with his hand in front of his face in a thinking pose. (00:04:30)
Quantom X Continuity mistake: When Ghazzi's car pulls up to the steps of the club in Moscow, you can see the bald bouncer at the door with nobody directly in front of him. The the camera cuts to the door with the bald bouncer there and suddenly the guy smoking a cigarette who greets Ghazzi with a hug just appears. (00:04:05)

Continuity mistake: In the opening scene as Ghazzi's car is about to pull up to the club, they round a corner at an intersection where the camera cuts to a different angle. There is a white van to the right of Ghazzi's car as they turn with nothing behind it, but in the next shot there is suddenly a smaller white vehicle of some sorts visible behind the van. Additionally, a third car appears on the left side, as a red vehicle next to the crowd of people at the club's steps. Thirdly, though it is very difficult to tell due to the shadows of the buildings, it might be that the three people walking past the red car suddenly appear between shots as well. (00:04:00)
Quantom X Continuity mistake: When Bruce Willis is shot, blood keeps appearing and disappearing on his face.

Continuity mistake: Declan gets a good shot off on the Jackal's leg that hits through the concrete wall. However when it cuts to the next shot the Jackal is holding a different part of his leg than where he was shot, and the hole in his pants and blood are gone. (01:49:45)
Quantom X Factual error: After the Jackal jumps to the other side of the metro subway train to get away, Declan pulls out his cellphone and makes a call. However in 1997, when this movie was made and the time it takes place, there was no way you would be able to get cellphone reception in a subway station underground. (01:48:00)
Quantom X Other mistake: The heavy caliber high powered mounted machine gun in the minivan with such a high cyclic rate would have recoiled so violently, that not only would the glass in the minivan shatter but it would have rocked the vehicle and kicked it around so that its shots would have been wild and all over the place after the first shot. Unlike how it's shown in the film. We are dealing with a 14.5 MM rapid fire cannon here. And when the gas tank is shot, the van isn't even shaking as the weapon is still firing. (01:43:50)
Quantom X Factual error: The big gun that the Jackal uses is shown to have a consumer grade lens on it. A mere camera lens. This weapon would have kicked so violently that just the first shot alone would have shattered the lens. This gun needs an optic that is designed for such weapons. (00:57:35)
Quantom X Factual error: When the gun is uncovered at the grounds where The Jackal and Lemont are about to test it, we get a good look at the scope mounted on it. This is a Canon Prime Lens, which is unable to zoom as is shown on the monitor. (00:55:35)
Quantom X Other mistake: When the FBI arrive with Declan at Isabella's house, in the top down view there is a dog barking and running towards the incoming FBI vehicles as they park. This dog is only seen in this shot and then is never heard from or seen again - not running up excited, or holding back from fear, still barking. (00:32:05)
Quantom X Factual error: When searching for a weapon to use to perform his hit, The Jackal requests a weapon that is identified as a Polish ZSU-33 14.5mm. However what's shown is actually a Browning M2HB mocked up as a KPV heavy machine gun in 14.5mm. Both of these weapons have a fire rate of about 600 rounds per minute. But the film states the Polish has a fire rate of 1400 rounds per minute.

Answer: It is stated that the FBI is working with their Russian equivalent, the MVD on a joint operation. The FBI primarily focuses on domestic issues but does on occasion engage in operations outside of the United States with the assistance and in the aid of foreign governments. The CIA would not be the appropriate government agency to handle the operation in the movie because that mission is a law enforcement operation. The CIA is strictly an intelligence gathering organization with no law enforcement authority.
