Paramount Vantage and Overture Films have announced that they are co-financing and co-producing a sequel to Fahrenheit 9/11 with documentary filmmaker Michael Moore. Overture will distribute the film domestically, while Vantage will handle international. The big news is that Moore is leaving The Weinstein Co, which distributed his last two films. The yet-to-be-titled documentary will be released in mid-2009. Depending on what source you read, Moore is either already working on the documentary or will begin production immediately following Cannes. The completed film could feasibly premiere at next year’s Festival, if it isn’t released earlier.

Details are being kept tightly under wraps but Vantage topper Nick Meyer claims the movie has “global appeal”. All we know is the sequel will pick up where Fahrenheit left off. And while you might expect an “I Told You So type story of how Bush ruined the country, insiders expect the film to be much more than that.

Moore has made three of the top five grossing documentaries of all time and the original Fahrenheit is the highest grossing documentary ever domestically, earning $119.1 million and another $100 million internationally.
