Factual error: Raceme's girlfriend Morgan is seen in a mugshot taken by Edinburgh Police, Scotland. They are known as Lothian and Borders Police, not as shown "Lothan and Boarders". (00:28:30)
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).
Casus Belli - S6-E5
Plot hole: Later in the evening, after NYPD takes Quinn into custody, Carrie finds his cell phone, with pictures showing their home had been spied upon from across the street, as well as other evidence of a conspiracy. He had tried to hand her the phone right after the police broke in, but it was knocked from his hand and she discovered it under the smashed door. In the real world, Carrie's home would have been considered a crime scene and the police would have searched it thoroughly, top to bottom, undoubtedly finding the phone themselves, but are shown driving away after the confrontation.
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)
Continuity mistake: Carrie opens the safe to take out her gun. The safe is closed when they take her with a hood. When Quin comes in the safe is open again.
Continuity mistake: Tom nails the notepad with the bullseye drawing onto the tree trunk, and when he fires at the target the notepad is nailed differently and the bullseye drawing is entirely different as well. (00:27:20)
Continuity mistake: After David listens to the recording that Carrie made in order to leverage the FBI, in the closeup facing David as he says, "For what? The hope that this Imam will give you information that you don't even know he has," David's right hand is empty as he holds it up, but it cuts to the shot facing Carrie and David's hand is still up though now he's holding his pen. (00:20:15)
Factual error: The man who approaches Carrie in the bar identifies himself as a 'lieutenant JG', and the pilot who bombed the wedding party in the farmhouse. However, it was F-15s that dropped the bombs on the farmhouse, making them US Air Force aircraft. The USAF rank structure doesn't include the 'JG' rank- that's a US Navy rank.
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)
Plot hole: When Brody is flown back he is wearing his uniform, complete with medals and name. But he has been missing for 8 years! Where is that uniform coming from? Not from his wife, because she just heard from him. (00:04:00 - 00:10:00)
Suggested correction: It would have been provided by the military, when he was cleaned up, debriefed and looked after immediately after his rescue. It's mentioned that he returns to the US via a base in Germany, I believe.
