When The Levees Broke

Spike Lee is going to present a four hour, four part documentary on HBO about Katrina and the aftermath later this month.
From the HBO site:
"On August 29, 2006, the city of New Orleans was forever changed when Hurricane Katrina made landfall, breaching levees, flooding neighborhoods, and killing more than a thousand residents. One year later, acclaimed director Spike Lee presents this four-hour, four-part HBO documentary event that recounts one of the United States' most profound natural disasters through words and images. In addition to revisiting the hours leading up to the devastating Category 5 storm, the film tells the personal stories of those who lived to tell about it while also exploring the underbelly of a nation where the divide along race and class lines has never been more pronounced."
