Argo

In 1979, six U.S. diplomats in Iran fleeing from the student invasion of their embassy manage to hide in the Canadian ambassadors' residence. A C.I.A exfiltration specialist (played by Ben Affleck, also directing) hatches an extraordinary plan to get them out.

Based on a true story, it's a very tense film, especially the scene at the airport where they try to convince the guards that they've been scouting locations for a film. Ironically, for a film about faking a film, it has become controversial for being elastic with the truth, and it does come across as Hollywood saving the C.I.A. saving their own people and down playing the role of other countries' involvement, especially Canada. It's worth a watch, though.
