Based on a true story, "Argo" is about a covert mission to rescue American's trapped in Iran following that country's 1970s revolution. The mission's premise: Stage the production of a fake big-budget Hollywood scifi movie that wished to film in Iran's "exotic" desert locales, and while there smuggle the would-be hostages out as part of the "production crew." Ben Affleck directs and stars.
Of special note for geek audiences: The non-film used designs from comics legend Jack Kirby as it's concept-art - Kirby will appear in the film, played by Michael Parks.
Amusingly, I've already been effectively called a racist once today in-part for not coming out against this movie because Affleck's character was Latino in real life.

I'm not sure what else I'm expected to say about that other than to note that I don't like Hollywood' insistence that white leads are needed to a open a movie
