Sahar, the Canadian ambassador's housekeeper, choosing not to reveal the identities of her employer's guests when questioned by the extremists.
The Canadian Ambassador and his wife, Ken and Pat Taylor, taking in and sheltering the houseguests. Truth In Film, as the Taylors remain beloved figures in the United States to this day for what they did.
Didn't actually make it into the film, but it was such a wonderful moment that it has to be mentioned anyway: in his work for the CIA, Tony Mendez regularly consulted with the State Department, and as such, regularly visited Foggy Bottom, and this continued after the Argo operation. Whom should he run into at the Metro Station there one day? Bob Anders! Mendez was just standing there when he hears someone call out "Kevin!" In Real Life, after all, Bob Anders and the other houseguests only knew Mendez by his cover-name Kevin Costa Harkins. When Mendez turned around and saw who it was, the two hugged. Anders was still in touch with the other houseguests, since they all still worked for State, so after catching up, they agreed to all get together again for a reunion barbecue at Mendez' house.
