Revealing mistake: When Tom Keen is on the phone at the end of the episode, he is holding the phone backwards with the screen away from his ear. (00:41:20)
Marvin Gerard (No. 80) - S3-E2
Revealing mistake: In the scene where Solomon kills the Russian convoy driver in the hospital, there is a black computer mouse pointer visible over the HR/min on the medical equipment display. (00:22:23)
Abraham Stern (No. 100) - S5-E11
Continuity mistake: In the beginning of the episode, Reddington is in a Mercedes S-Class driven by Dembe. This specific car model is mainly used by Reddington in his travels. The car is a 2013 W222 Mercedes S-Class. The interior is also depictive of the specific model W222. Suddenly, he gets into a car accident where the Mercedes he is in is not a W222 but a W221, an older model from 2006 to 2013. (00:00:08 - 01:10:00)
Helen Maghi (No. 172) - S9-E16
Factual error: Harold tells Raymond he'll repay the bail money, but given he's pleading guilty and fully intends to go along with required court appearances, etc, the bail money paid will be refunded - it's not like Raymond is out-of-pocket.
Revealing mistake: Aram "hacks" an employee database via a company website - the code that's briefly visible on screen (slo-mo helps but isn't required) is just standard HTML that lays out a web page, not server commands.
Revealing mistake: In scene where Liz is telling captive ex-husband, Tom, that she will let him go after he helps her get Berlin, Tom gets up and you can see the chain on his leg is only held to the floor with a chain link that just screws closed.
Factual error: When they cut to "Dresden, Germany" on the picture that is Budapest, Hungary. The bridge on the picture is the Chain Bridge. The camera is on the Pest side. (00:15:30)
Revealing mistake: When Elizabeth Keen removes the tape from Amalia's mouth after rescuing her, she briefly reveals the sticky side of the tape to the audience, showing another large swatch of tape attached to what should be the sticky side. This was done to prevent the actor's skin and provide easier removal.
Dr. Laken Perillos (No. 70) - S8-E10
Continuity mistake: At the start, Reddington and Dembe are talking to a garageman. He has a protective helmet on him. They zoom in and out of him, and show him from side and front. The strap on his helmet is different every time. One time it's over his ears, one time fully above it, and the next is sits low on his ear. All this within a short minute-long talk.
Factual error: Norfolk Naval Base is located on completely flat terrain and the areas around the base is devoid of trees in all directions for miles. The scene shows the ship with a tree-filled hillside across the water. Obviously the scene was not shot in Norfolk, VA. (00:32:08)
Mako Tanida - S1-E16
Continuity mistake: After Mako Tanida gets Agent Raim, the camera shows his pant leg with a visible tear in it exactly where Tanida later cuts it with his blade. (00:01:27 - 00:02:15)
Dr. James Covington (No. 89) - S2-E3
Factual error: The doctor at the start asks for 0.05 of lorazepam. This dose doesn't make sense - a normal dose might be somewhere from 0.5-4mg. (00:00:30)
Louis T. Steinhil (No. 27) - S7-E1
Factual error: In the beginning a woman is counting brown 200 Euro banknotes. 200 Euro notes are yellow.
Continuity mistake: When Emma and Jessica are waiting for the other two, Emma is looking at herself in the broken side mirror, and Jessica is leaning on the hood next to her when the van pulls in. In the next shot, with the van still pulling in, Emma and Jessica are now standing in front of the Cadillac.
Continuity mistake: The knife hole and blood on the envelope of the note to Scottie Hargrave changes. In the first close up, the name is aligned to the middle of the hole and there's a trail of blood running down towards the corner. In Scottie's hand, the hole/blood is higher up and the trail of blood is gone.
Other mistake: When Paul goes into the bank he's carrying the money bag. When he is seen walking into the bathroom for the first time, he isn't carrying the bag, which is already on the windowsill.
Nicholas T. Moore (No. 110) - S5-E20
Continuity mistake: When they are in the hospital, Elizabeth is talking to the young girl and she closes the door behind her. The next time the camera shows Elizabeth's face the room door is open behind her. (00:06:15)
Visible crew/equipment: There are two men in the flat near Elizabeth, even though Elizabeth and Mr. Kaplan are alone in the room. (00:18:35)
Other mistake: It shows an eagle-eye view of the downed plane with the pontoons floating separate from the plane; the plane starts to sink more and Agent Keen incorrectly says that one of the pontoons is taking on more water, even though they aren't attached to the plane and keeping it afloat anymore. (00:05:55)
Natalie Luca (No. 184) - S4-E12
Audio problem: At the end of the episode when Reddington goes to see Natalie Luca (behind glass), he tells her that the woman she killed at the massage parlour was an associate of his. When Natalie says "She said if I didn't kill him, she would tell Hawthorne where to find us", her lips don't match what she's saying in the reflection of the glass.
