The announcement was made Thursday by Overture Films and Paramount Vantage.
The film is not yet titled. Moore earlier planned to make it more broadly about America as an empire. Instead, the documentary explores the causes of the global economic meltdown. Moore has called it "the biggest swindle in American history."
The division between rich and poor is old territory for Moore, who broke through 20 years ago with "Roger & Me" _ about General Motors closing a plant in his hometown of Flint.
Moore won the Academy Award for best documentary in 2003 for "Bowling for Columbine."
