Argo might well be studied as a bait-and-switch masterwork: In showing the capture of the American Embassy in Tehran, Ben Affleck first made a fetish of authenticity, then served up a shamelessly Hollywood, and wholly fictional climax, then capped the whole thing off with a coda that was essentially a tribute to his movie's authenticity, complete with side-by-side photos of the actors and their near-identical real-life counterparts. Well done, sir!
