Factual error: Error in the Istanbul scene. Ben Affleck is shown entering what looks like the Blue Mosque in Istanbul. We are shown the outside and the courtyard of the Blue Mosque with its distinct blue rooftops. When Ben Affleck is meeting another dude inside, they are inside the building which now serves as a museum and which is known as "Hagia Sophia." (00:48:40)
Continuity mistake: Ben Affleck gets into a 280s Mercedes driven by the Canadian Ambassador. The front screen wipers on the car are original silver chrome style and fit the screen. When they arrive at his house the wipers have now changed to much shorter modern style wipers, are black, and are the very latest frameless style first introduced in the early 2000's by Bosch.

Factual error: In the final scene where the Swiss Air 747 is taking off, the police cars are travelling right behind the engines of the jet. They would have easily been blown away by the engine. (01:41:15)
Factual error: They play a track "When the Levee Breaks" from a Led Zeppelin album. The hand shows the needle being placed at the next to last track on the album. However, "When the Levee breaks" is the last track on Led Zeppelin IV's second side. (01:18:30)
Factual error: In the beginning of the film, when Agent Mendez is called to CIA Headquarters, as he passes the secretary's desk, the outgoing letter propped against her word processor has two postage stamps affixed (2-cent Navajo necklace & 37-cent US Flag) which were first issued and then reissued by the US Postal Service beginning 2003-04, 23+ years after the hostage event in 1980. (00:14:10)
Continuity mistake: As the actors all gather around the table to begin reading the Argo script aloud to the media, we see a two shot as the C-3PO character takes a seat at the table. In the next shot (a wide shot), we see the C-3PO character standing in the background, preparing to take his seat. (00:39:55)
Continuity mistake: There is a scene after Tony came up with the idea for the fake movie and presented it to the CIA, where he is looking at papers under a magnifying glass. Tony is holding his cigarette in his left hand under the magnifying glass. The very next shot shows his face, and he suddenly has the cigarette in his mouth. Which he then removes with his right hand. The next shot shows it in his left hand again. (00:25:10)Quantom X
Factual error: The embassy takeover was November 3rd. A scene in Washington DC described as 69 days later showed Tony Mendez driving around town with yellow/fall like leaves on the trees, something that would not have been true in the middle of January. A similar scene at the end of the movie has Tony Mendez approaching his house in Virginia and a very fall like scene is shown. (00:13:45 - 01:49:00)
Factual error: As a newspaper from January of 1980 is displayed, the Rolling Stones song "Little T&A" is played. That song appeared on the "Tattoo You" album, which was not released until Aug. 24, 1981.
Factual error: The Canadian military policeman (Sgt. Claude Gauthier - based on a real person) depicted as the house guests leave Ken Taylor's residence, and subsequently shown breaking up communication equipment has several errors in depiction. He is shown wearing combat uniform while on diplomatic duty (although perhaps the situation excuses this). He has service dress sergeant's chevrons sewn on the arm of his combat uniform instead of combat uniform rank. He is wearing a military police red beret, but at that time Canadian military police wore green berets. Also, having enough years of service to attain the rank of sergeant, he would have known how to form his beret properly, rather than having it look like a pizza. The slip ons worn on his shoulder epaulets are way too long, and are not like any Canadian Armed Forces slip ons for any uniform. They are definitely not Canadian combat uniform slip ons. The chest pockets on the combat shirt are sewn flat, whereas in reality the chest pockets had sides (they stuck out from the shirt) as they were designed to hold ammunition magazines for the FNC1 rifle. The buttons on the chest pockets are small, like the ones running down the front of the shirt - the pocket buttons should be much larger in diameter than the shirt front buttons, His long hair and sideburns would not have been permitted under the dress and deportment regulations of the Canadian Forces, and as a Sergeant he should have known better.

Factual error: CIA agent Mendez takes-off from Washington to Tehran, apparently via London because he boarded a British Airways flight, on a twin engine aircraft. Twin engine aircraft flights across the Atlantic were just being introduced by TWA around 1980 and weren't flown by BA until years later, if at all. Also, the BA Boeing 747 depicted had tail colors that were not introduced by the airline until the early 2000s. (00:46:35)
Factual error: The turbans worn in the scenes in Tehran are not the sort worn by Iranian clergy - they are wound incorrectly and are too flat.
