Factual error: Before Jonas discovers Quinn is gone, he calls the emergency number, which is 112. However, the lady on the phone says "zwei eins eins" (211).
Factual error: The President's casket is being brought into hanger at Dover AFB Delaware. There are no mountains in Delaware as was seen in the background.
Factual error: Almost anytime where an ipv4 address is shown it contains one or more digit exceeding 255, impossible given the limits of the technology. eg: 257.100.23.59, 23.274 .44.67, and even 316.105.147.373. (00:04:55)
Super Powers - S5-E3
Factual error: Carrie loads a rifle with at least a 7mm Remington, possibly a .30-06 Springfield bullet. She shoots Quinn in the back one time, and he falls, only to disappear and reappear where he chokes Carrie from behind. He later removes his jacket to reveal he's wearing a soft armour bullet proof vest. The armour he wore was maximum level 3A vest which will only stop handgun threats. He would require a plate carrier with SAPI/ESAPI ceramic plates to stop such a threat. (00:55:37 - 00:57:10)
Factual error: Filming location is Budapest instead of Moscow, you see HU license plates on cars, HU street name tags, and even the flag of HU and the EU waving over the building Carrie is on.
Why Is This Night Different? - S5-E4
Factual error: The airport is shown as Douvaine in Switzerland. Douvaine is actually in France.
Continuity mistake: When Brody is driving Nassir Faris, the trim on the passenger side dashboard sometimes has a light metal-like finish and sometimes is woodgrain. In other episodes, it's the light finish.
Factual error: At the beginning of the last sequence a city centre is shown with the caption "Moscow." In fact, the city shown is Budapest, with the Danube, Castle, St Matthias Church, Fisherman's Bastion and Chain Bridge visible.
Continuity mistake: When Carrie waits to "accidentally" bump into Brody outside the CIA building, watch the extras really making a mess of the continuity.
Continuity mistake: When Carrie is talking to Brody from across the room, her hair jumps several times between being tucked behind her ear to hanging down by her face. (00:20:30)
Other mistake: Carrie took Finn back to hospital and after he left the car he lifted his left arm up and brushed back his hair. I thought he couldn't move his left arm?
Character mistake: Carrie is back at CIA for a 6 pm brief. She takes a seat waiting to be called. She puts her purse under her chair. Shortly, her patience runs out and she says she is going to bathroom. She tries to enter the briefing and David escorts her out. She immediately enters the elevator and leaves. Her purse is still under the chair in the waiting room - presumably with her car keys, wallet etc.
Clean Skin - S1-E3
Other mistake: At the river, kids are smoking pot and the guy with dark hair is telling Brody's daughter they are the perfect family. When he finishes, he is obviously rehearsing his next lines and his mouth is moving. (00:07:50)
Chosen answer: Everyone else calls him Brody or Sgt. Brody, and it probably became habit to her.
The_Iceman
Can't get the source but I read that even the Producer responded to that. Stating that it was common practise for a military wife living in a military complex as everybody refers to their husband by their last name.
