From NetFlix:
In 1979, when Iranian militants seize the American embassy, six Americans slip into the Canadian embassy for protection, prompting the CIA to concoct an elaborate plot to rescue them by pretending that they are filmmakers rather than diplomats.
From the Wikipedia article we learn:
Upon release, Argo received widespread acclaim and also received seven nominations for the 85th Academy Awards and won three, for Best Film Editing,[7] Best Adapted Screenplay, and Best Picture. The film also earned five Golden Globe nominations, winning Best Picture – Drama and Best Director, while being nominated for Best Supporting Actor for Arkin.
From that same article you can read about reactions of the Iranians, reactions of New Zealand, and historical inaccuracies. Initial subtitles put that historical period into perspective, telling us just how we got into such a mess. From one point of view it is no wonder the Iranians hate us.
Tony Mendez, the real-life CIA agent, must have been an amazing person. For 120 minutes you will be sitting on the edge of your chair hoping he can help the six Americans escape. Scenes were contrived to heighten that suspense. For example at the very end of their ordeal, as the 6 Americans and Tony Mendez have just gotten into the plane and that plane is slowly maneuvering to take off into the air, there are truckloads of angry Iranians racing down the runway trying to stop the takeoff.
If you can stand the excitment, DO NOT MISS THIS FILM!
