Mr. Moore and his distributors have refused to circulate copies of the film and its script before the film's release this Friday; his production team said that as of last Wednesday, there was no final script because the film was still undergoing minor editing — for clarity, they said, not accuracy.

As proof of its scrupulousness, the Moore team cites adjustments it made to the film's portrayal of Attorney General John Ashcroft. The film is brutal to Mr. Ashcroft, depicting him as a glassy-eyed architect of efforts to shred the Constitution, who became Attorney General only after he proved himself so unpopular in his home state of Missouri that he lost a Senate race to a former Democratic governor who died in a plane crash a month before election day. "Voters preferred the dead guy," Mr. Moore deadpans in the film, a line that drew belly laughs at recent preview screenings. (In reality, voters knew they were in effect casting ballots for the governor's widow).

An earlier version of the film, however, included a reference to a widely circulated charge, broadcast by CBS News in July 2001, that Mr. Ashcroft had received warning of threats and stopped flying on commercial airlines. Tia Lessin, supervising producer of "Fahrenheit 9/11," said the reference to the CBS report was cut after Mr. Moore's fact-checking team found evidence that Mr. Ashcroft had flown commercially at least twice that summer.
