You could describe Margin Call as a thriller (it's wired with suspense), yet the tension all comes from words.

The movie with which it has the closest relationship may be "Glengarry Glen Ross." The same sense of desperation, the same need to make the sale, permeates Margin Call. Both films are to some degree about the dehumanizing impact of money and both are driven more by characters than plot points.

J.C. Chandor's precocious writing-directing debut is fastidious, smart and more than a bit portentous as it probes the human costs of unchecked greed.

A hell of a picture. And shrewd.

This compelling-acted film explains, better than any soundbite, why people have taken to the streets, "occupying" centers of finance. If their rage is unfocused, Margin Call suggests, that's with good reason. There are no real heroes or villains here, just human beings with human failings making BIG human mistakes.
