As he did with the occupation of Iraq in No End in Sight, Charles Ferguson shines a light on the global financial crisis in Inside Job.

Accompanied by narration from Matt Damon, Ferguson begins and ends in Iceland, a flourishing country that gave American-style banking a try - and paid the price.

Then he looks at the spectacular rise and cataclysmic fall of deregulation in the United States. Unlike Alex Gibney's fiscal films, Enron: The Smartest Guys in the Room and Casino Jack, Ferguson builds his narrative around dozens of players, interviewing authors, bank managers, government ministers, and even a psychotherapist, who speaks to a culture that encourages Gordon Gekko-like behavior, but the number of those who declined to comment, like Alan Greenspan, is even larger.

Though the director isn't as combative as Michael Moore, he asks tough questions and elicits squirms from several participants, notably former Treasury secretary David McCormick and Columbia dean Glenn Hubbard, George W. Bush's economic adviser.

Their reactions are understandable, since the borders between Wall Street, Washington, and the Ivy League dissolved years ago; it's hard to know who to trust when conflicts of interest run rampant.

If Ferguson takes Reagan and Bush to task for tax cuts that benefit the wealthy, he criticizes Clinton for encouraging derivatives and Obama for failing to deliver on the promise of reform. And in the category of unlikely heroes: former governor Eliot Spitzer, who fought against fraud as New York's attorney general (he's the subject of Gibney's documentary Client 9).
