When Aaron gets into the cab (where he receives the first call from N. Korea), the medallion number of the cab is 5D32. The camera then cuts to outside the cab where the license plate reads: 7X41. NYC Taxicabs have the same medallion number and plate number.
When Aaron has the meeting on the mountain one of the soldier's gun sight moves position from scene to scene.
When Dave and Aaron step off the plane in North Korea, there is a large line of what looks like soldiers behind the small crowd around Sook-yin Park and in front of a row of flags, when the camera faces them directly. But when the camera pulls around to the side and behind for wider shots, the crowd is nowhere in sight.
Throughout the film, several North Koreans refer to their country as "North Korea." No North Korean would refer to the country by that name. The official name for the country is the Democratic People's Republic of Korea and they view themselves as the sole legitimate government of the entire Korean peninsula.
Ricin is not lethal if it comes in contact with skin, rather it only causes skin redness and pain. The plan would never have worked as intended.
Jong-Un Kim is several times throughout the film referred to as the president of North Korea. However, the title of president is reserved for his late grandfather, Il-Sung Kim, who holds the title of "Eternal President". Even if the Americans didn't know this, the North Koreans would never have let this mistake go uncorrected. Kim Jong-un is normally referred to as the "Supreme Leader" of the country.
During the actual interview between Dave Skylark and Kim Jong-Un, Sook and Aaron Rapaport produce the show. However, when the control booth is emptied, the camera angles continue to change in the broadcast.
While still in New York, Skylark's broadcast is interrupted by a news alert about North Korea. This could never happen in an actual situation, the producers of the newscast would have been required to give a minimum 3 minute warning before taking their air.
Near the end of Skylark's interview with Kim Jong Un, Aaron and Sook leave the control room. However, preceding shots which are shown of the broadcast show a live switching of cameras, an impossible action which would be done by a technical director in the now empty control room.
In the opening scene when Dave Skylark is interviewing Eminem, Dave is not wearing any earpiece on either one of his ears, yet Aaron can talk privately to Dave through the mic such as when Aaron gives him instructions or dictates the lyrics of Eminem's "Medicine Ball" song for Dave to repeat. Eventhough Dave is pressing his right ear with his finger when he repeats the lyrics, as if to hold and push the earpiece deeper so he could hear better, when he removes his hand from his ear, it's clear that there's no earpiece there. Without any earpiece on his ear, Dave would not be able to hear Aaron.
There are several errors with the control room scenes both in North Korea, and in New York. Firstly Aaron seems to randomly jump in with camera cuts, even though he is a producer, and that is the job of the show's director, who in both locations is non-existent. Secondly, some of the graphics on the monitors appear to have no relation to the show, some look like open photo editors, and others have unidentifiable green charts on them that would be useless to anyone in the room. In addition, the graphics shown on these screens are several different varieties of "Skylark" different from the ones that the show used anywhere in the movie. The one set of screens that is accurate in the room is the screen displaying inputs, although the "titles I - IV" and "A" are all blank, color bars, or off the air. These screens are used to display the various camera angles from the studio, although there are no camera angles present anywhere on the screen. Which must mean Aaron memorized all of the cameras numbers and locations and is somehow constantly aware of what angles they have. Seven of the monitors show the same screen, and three of them are blocked by other monitors, rendering them partially useless. There is also no network clock in the room, which in reality would be used to start the broadcast correctly during its time slot. In North Korea, there is a joystick that Aaron uses to change the angles of the cameras, even though they are regular studio cameras that are controlled by the cameramen. When switching cameras in the North Korean studio, Sook seems to use a line of buttons with various camera numbers on them. However, again there are no monitors displaying these angles, and this process would actually be done using a switcher.
Skylark's show makes no sense from a broadcasting standpoint. There is no teleprompter shown in the control room or the set in either country. Yet, Skylark recites lines throughout the show as if he's following a script. Aaron begins the show by saying "Action" which is not only not his job, but also would leave Skylark without audio or a cue, and the broadcast stuck on the last frame of the intro track. As the various people in the control room have to be directed to switch various things on and off and change inputs and cameras.
Obviously that the three kids aren't playing their guitars since they don't make any movements with the left hand.
When Dave and Aaron are talking, just before the actual interview, square LED studio lights can be seen reflected in Aaron's glasses.
The area around Dandong in China, where Rapoport goes to meet Sook, is depicted as wild and underdeveloped. This is inaccurate. Dandong sits on the Yalu River delta and is a modern city with an airport and a rail link to Beijing and into North Korea.
Near the beginning, the globe showing a missile trajectory from NK to the US West Coast depicts an impossible route. ICBMs take a Great Circle route (shortest path). The misconception portrayed is important. Any NK missile would have to fly over the Aleutian Island archipelago, an area heavily defended by U.S. anti-missile technology. The erroneous route depicted would be much more difficult to defend, and thus exaggerates West Coast vulnerability.
(at around 16 mins) The train passing to the right in the second stock shot of a Chinese train is actually an double deck Intercity train from the Swiss Federal Railway, not Chinese.
