I am not entirely sure what a tour de force is, but is certainly sounds impressive.
|Ben Affleck as a CIA agent|
Lots of CIA intrigue in it. Mostly it shows that our government can get things done, but largely in spite of itself. The top dogs of the government don't come off well. Only the misanthropes, like the character played by Ben Affleck seem to navigate it well.
All the actors did a great job in this film, though John Goodman and Alan Arkin really went over the top in their performances. More of that tour de force stuff.
|Arkin and Affleck|
The story line is dramatic - U.S. hostages during the Iranian crisis of 1979-80 need to be rescued from the Canadian embassy where they are hiding out.
But beyond that, no spoilers here. Watch Argo instead. It's worth it, especially the final few scenes.
