It was one of his colleagues who had a chance encounter at that conference with Nicholas Berg and wound up interviewing him. It's the only footage of the young man who later was beheaded in Iraq.

Although inundated with requests, Moore decided not to release the interview to the press or incorporate it into "Fahrenheit 9/11." "I wasn't going to put him in it because now he is famous because he was killed. I gave (the footage) to his family. It's a private thing they can choose to do what they want with. It was just the right thing to do.''

The White House and the Republican National Committee have taken a "no comment" approach to Moore's film. But many Bush partisans are outraged. "It's a recruiting film for al-Qaeda," says conservative California Republican Howard Kaloogian, head of the effort that successfully lobbied CBS to pull the docudrama The Reagans from its schedule last year, and the force behind a campaign pressuring theater owners not to show Fahrenheit.

Moore also withheld a 20-minute interview his crew had with Nicholas Berg, the 26-year-old West Chester telecom worker whose videotaped beheading in Iraq stunned the world in May. None of the exchange, conducted at a Stateside job fair in December, was included in Fahrenheit's final cut. When the news came of his death, Moore gave copies of the video to Berg's family alone.

"The media begged for it, offered to pay a lot of money for it," Moore says. "But we thought the Berg family should have its privacy."

Moore says most Americans assumed the president left the school as soon as he received the information. The filmmaker noticed Bush had been in the building six to 10 minutes longer than reports suggested.

"We were thinking, 'How can we get this?' Someone said, 'I wonder if the school videotaped the event?' We called the teacher. 'Oh yeah, we have a tape.' 'Can we have it?' 'Sure.' 'Has anyone else ever asked for it?' 'No.' That's all it required."

Moore also conducted an interview with Nick Berg, the American who was beheaded in Iraq. The conversation took place at a conference in the United States, before Berg's departure.

"We had it in an earlier version. We weren't going to put it back simply because he lost his life. We thought the family should have the footage . . . We were offered lots of money to sell it. We wouldn't do that."
