Appearing some time after the book allowed the documentary film to address many of the items that Yergin and Stanislaw missed in their original book, including the collapse of Asian economies, the anti-globalization movement and the September 11 attacks. All told, two of the documentary's six hours (the entire final third) address things that happened since the original book was published. They also include free market solutions to international poverty that were not included in the book, and they interview economist Hernando de Soto, whose book on the subject was not published until after the initial printing of "The Commanding Heights".
