When narrating the story about early stages of his business in 1980s, Yuri Orlov mentions that he has carried several passports at that time, including the Ukrainian passport. Ukraine didn't get to issue its own passports until 1992.
At the beginning of the movie, after the scene changes from introduction to Ava Fontaine back to Brighton Beach in the 1980s, the car wreck that we see is of a 4th generation Toyota Camry which was produced from 1997-2001.
During the first scene in the restaurant kitchen (set during the Carter administration), a spice jar above the stove prominently features the recognizable black-and-white "Nutrition Information" block that didn't appear on products until the early 1990s.
During Yuri's 'first break' in Beirut in 1984 the rifles he is selling are marked "AR-15 A2", as can be seen during the close-up shot. Peace keepers would still be using the "A1" model. The A2 was introduced shortly after this particular conflict.
In the arms fair scene set in 1983, Yuri says that Weisz "sold" to both sides during the Iran-Iraq War. Weisz also speaks in the past tense when referring to that conflict. The actual time period of the war was 1980 to 1988, so the war was still going on in the timeframe of this scene.
The car used by Yuri throughout the film is a Cadillac Fleetwood Brougham limousine. The particular model shown was introduced in 1993, yet Yuri has this car already in some scenes which are supposedly happening in the late '80s.
When Jack Valentine shows Yuri Orlov a newspaper (dated May 23rd, 2001) in an interrogation room, an article about a death of an alleged pro-communist activist and following events in Korea appears on the left column of the paper. Though the events that referred to in the article are actual events, they happened in 1987, which is fourteen years before the date on the newspaper.
When INTERPOL has Yuri and his uncle at gunpoint, asking for his papers, Jack Valentine asks whether the ship they met on before was named the Kono or the Kristol. Right after Yuri replies with a smart comeback, the INTERPOL agent to the left-hand side of Yuri supposedly cocks his gun telling him to "answer the question". The INTERPOL agent who supposedly cocks his gun has his right hand holding the gun, and clearly has his left hand on Yuri's shoulder while the gun is cocked. None of his hands could have cocked the gun.
When Yuri and Uncle Dimitri discuss the arms stockpile Yuri mentions that it's "dangerously depleted for a battalion" with "only" 10,000 assault rifles. However, the average infantry battalion has about 500 riflemen, so 10,000 rifles is a ridiculous amount. Also, as a Major-General, Uncle Dimitri would not be in charge of a battalion, but of a division (in which case a stockpile of 10,000 rifles would make considerably more sense).
Yuri's voice over claims the "U.S. Army" got a cut of his sale in Lebanon in the form of Lieutenant Colonel Southern, but the officer was wearing a Marine Corps uniform and wearing Colonel (not Lieutenant Colonel) rank. Lieutenant Colonel rank, whether Army or Marine, would be represented with a silver oak leaf, not an eagle. Additionally, this Marine Colonel is wearing the cap of a General but the Emblem of an Enlisted Marine, which makes the rank and service of his entire uniform incorrect.
Yuri's uncle Dmitri Orlov is introduced as a Major General and wears two stars on his shoulder boards. Although two stars means a Major General in the US military, in the Soviet/Russian Federation Army two large stars means a Lieutenant General, which is a higher rank than Major General.
During the 1983 arms fair, Orlov claims the Simeon Weisz sold the Exocet missiles used in the Falklands war. Those particular Exocet missiles (French made air-ship weapons used by the Argentinean Armada against the Royal Navy) were directly brought by Argentinean president Leopoldo Galtieri from the French government. In fact, this resulted in an unpleasant reunion involving French president François Mitterrand and the British government under Prime Minister Margaret Thatcher during the peak of hostilities. No arms dealers were involved, but it is possible that for film reasons movie makers made it so.
During one of Yuri's narrations, he says that the AK-47 assault rifle is made of "forged steel and plywood." While some versions of the AK-47 do have laminated wood stocks and handguards, it is incorrect to refer to that material as "plywood."
When Ava confronts Yuri about his real occupation, she is seen naked from behind. She then slips on a bathrobe. Shortly afterward she is seen kneeling in front of Yuri while he is sitting on a sofa, and it appears that she is wearing underwear (bra and panties) beneath the robe.
When Ava Fontaine enters the container used for Yuri Orlov's gun running business the first section of guns are as follows "Top AK-47", "Bottom M-16 or AR-15" but when the camera shows Ava's perspective they are "Top M-16 or AR-15", "Bottom M-16 or AR-15" and then back to the "Top AK-47", "Bottom M-16 or AR-15" when the camera pulls away form her perspective.
After finishing the painting of "Kono" and while they are bringing the painter back up aboard, we see all four letters filled out nicely and without smudges. However, in a short cut the N in Kono is smudged, and then back to normal in the very next cut.
In the opening kitchen scene with Vitaly, there is a vodka bottle up on the shelf. When the camera closes in on Vitaly's face the label is pointed to the left. They cut to Yuri and then back to Vitaly. When they do, the label is turned to the rear.
When Yuri is in his apartment looking down out the window, you can see the Interpol truck is almost completely in the sun. In the next shot, when you see Jack stepping out of the truck, the entire truck is in the shade.
In the scene where Yuri, Vitaly, and Andre's son are traveling to Sierra Leone, Jared Leto's tattoo representing his band '30 Seconds To Mars' is clearly visible on his right arm. In no other scenes is this tattoo visible.
After Yuri's plane is forced to land in Sierra Leone, there is a scene in which a machete is held to his throat while he is being threatened by INTERPOL agents. The position of the blade against his neck moves back and forth between shots.
While en route to Sierra Leone from Liberia, Yuri and company travel though a dry and desolate desert. However, both Liberia and Sierra Leone are in a tropical climate zone, and do not have any deserts such as the one shown. They would most likely be traveling through savanna or rain forests between the two countries.
When Yuri telephones home from the Ukraine, he wakes up his wife in the middle of the night (say 11:00pm-5:00am, total darkness). That would be daytime where he is (about 1:00pm-7:00pm), but the movie shows a night scene.
At the end of the film it is said that "The world's biggest arms suppliers are the U.S., U.K., Russia, France and China." This is incorrect. According to information from the Stockholm International Peace Research Institute, the five biggest arms exporters in 2005 were, in descending order: USA, Russia, Germany, France and U.K., while China is the 11th.
The Soviet troops under General Orlov (Yuri's uncle) all carry Norinco Type-56 assault rifles, a Chinese-made copy of the AK-47 that is distinguished by its smooth receiver cover and hooded front sight. It would be inaccurate for Russian soldiers to use Chinese-made AKs, and furthermore, the 7.62-mm AK variants had long been phased out of Soviet service at the time in which the scene takes place (early-1990s). The Russian troops would actually be armed with 5.45-mm AK-74s.
In his monologue about the AK-47, Yuri proclaims that the gun was on Soviet coins and on Mozambique's flag. While several African nations have put the AK-47 on their flag and/or coat of arms (including Mozambique), the AK-47 was never featured on Soviet currency.
During Yuri's narration upon entering the hotel in Liberia he says, "In the most AIDS infested region of the globe, where one in four is infected ..." This is untrue for West Africa and particular for Liberia where since the identification of HIV, the prevalence rate has never reached 2%. In fact, in 1995, when Yuri is in Liberia, only 23 people in the entire country had tested positive for the virus. Even if the regional reference was meant to indicate the entire Sub-Saharan Africa region, the "one in four" statistic is still grossly overestimated as these high rates only exist in a few Southern Africa countries.
In order to camouflage his gun-running freighter, M/V "Kristol", Orlov has the name repainted as "Kono". However, this only happens on the stern. A vessel also has its name shown on both the starboard and port side of the bow, so the agents bringing up the vessel would still have identified the ship correctly. Furthermore, the stern of a ship also sports the home port, which also would have had to be changed for the "flag-change" ruse to work, but is nowhere to be seen in the movie.
As Orlov's cargo plane is being intercepted over Sierra Leone,
it is repeatedly referred to as "Charlie Echo India," supposedly the phonetic call letters for an aircraft with the registration CEI. However, the registration on the side of the cargo plane clearly has the last three letters CIH, which would be referred to as "Charlie India Hotel" in the alphabet.
When Yuri sells Glock handguns to the drug dealer, two of the Glocks are 3rd generation models not sold until 2000. The Glock 3rd generations were not sold in 1980. The other two Glocks are 2nd generation models that fit the era. You can tell the difference between them because the 3rd generation Glocks have accessory rails, finger grooves in the grip and a thumb groove. 2nd generations have flat handles, no thumb groove and a slanted front nose.
In the opening scene, the cartridges being manufactured are shown packed loose into wooden crates, which is incorrect. In reality, the cartridges would be sorted, bundled into paper packets or cardboard cartons, sealed into large rectangular sheet-metal "spam cans", and finally packaged in a wooden crate. (Each crate contains two "spam cans" and a long sheet-metal can opener).
About 56 minutes into the movie two men are seen in Liberia carrying AK-47s. They also wear lengths of belted ammo. AKs require an adapters to fire belted ammo which are not shown. The AKs being carried have magazines in place. The ammo worn is too long to be 7.62x39 conventional AK ammo and is more likely to be 7.62x54r ammo.
Interpol has no arrest authority in the US, but then again they have no arrest authority in most parts of the world. Interpol acts as an intergovernmental organization facilitating international police cooperation.
In the scene where Jack Valentine enters the port, the name on the entrance "Port Odessa" (in Russian) is backwards so that it can only be read from the inside of the port not from the outside correctly.
When Valentine is asking Orlov what he's doing in Africa, he replies to his safari lie by asking if he's hunting with a sub machine gun, the type of bullet Valentine holds is irrelevant, Valentine already knows Yuri ships sub machine guns, he is just showing Yuri the bullet to further demonstrate his point that he knows Yuri is lying.
A Liberian guard wears a beret with an emblem of two crossed swords on oak leaves. This is a German emblem. However it is not uncommon for soldiers in West African armies to not be issued official fatigues or uniforms. Instead they often will wear second hand clothing that they find in the local markets. It is possible that the soldier bought the old German army beret.
In the Beirut scene, Vitaly draws a Beretta 92SB pistol. The 92SB was equipped with a hollow guide rod, so while it may appear to be missing the guide rod, it is there and the pistol would fire normally.
In the opening scene the label on the cartridges crate is full of goofs. It says "Odessa, Ukraine", while there have never been any kind of firearms plants in Odessa, Ukraine. It says "quantity 1588", but the crate is apparently not big enough to hold 1588 cartridges. Even the crate itself is a goof - AK cartridges (and most other ammo) are shipped in metal boxes.
Both times Yuri takes Vitaly to rehab, the exact same close-up shot of Yuri's hand pouring cocaine out of a vile on to the arm rest of their limo is used. It is colored differently the second time it is used, but it is still the exact same shot.
Aboard the Kristol, Yuri narrate about how AK-47's were codenamed Angel Kings. he then speaks on the phone saying that "the Angel Kings will arrive tomorrow", later just after Jack Valentine has left the ship, the camera shoots some potatoes falling to reveal a crate of guns, labeled M-16, which would suggest that the content of the crate is M-16 Rifles and not AK-47's.
The goof items below may give away important plot points.
When Vitaly throws the grenade into the back of the first truck, he quite obviously makes it about halfway between the two vehicles. However, by the time the truck explodes, he is only about a quarter of the distance.
When Jack and Yuri are sitting down for a talk after Yuri gives all his guns away to the Sierra Leone locals, the sunlight shining on Jack is inconsistent between shots. When the camera is facing Jack, you can see sunlight shining through his right ear and onto the right side of his face, but when the camera is facing Yuri, the right side of Jack's face is not exposed to the sun.
