Bad news for those who care about truth in documentary filmmaking:

Michael Moore plans a follow-up to “Fahrenheit 9/11,” his hit documentary that assails President Bush over the handling of the Sept. 11 attacks and the war on terrorism, according to a Hollywood trade paper.

Moore told Daily Variety that he and Harvey Weinstein, the Miramax boss who produced the film, hope to have “Fahrenheit 9/11 1/2” ready in two to three years.

And why wouldn’t he make a sequel? He apparently made $21 million on the first one.
