The Big Short is a new movie based on Michael Lewis’s book of the same name about the sub-prime mortgage crisis in 2007 - 2008. The film tracks the actions of a handful of investors who predicted that the housing boom would blow up and create havoc in the financial sector. They bet against the mountain of mortgage bonds and made fist-fulls of money. As the story unfolds, thriller style, The Big Short does a good job of explaining why the sub-prime and related financial products came to a bad end. This makes the film a good companion to an Oscar winning documentary Inside Job (2010) which takes a broader look at the financial crisis, the global economic crisis it triggered, and those who the filmmaker felt should be held accountable.
