Michael Moore says he has footage of a 20-minute interview with Nick Berg.

NEW YORK - Filmmaker Michael Moore, whose incendiary new documentary lambastes President Bush’s handling of the war, said Thursday that he has footage unused in the film of Nicholas Berg, the American civilian later beheaded in Iraq.

The footage, of an interview with Berg, “is approximately 20 minutes long. We are not releasing it to the media,” Moore said in a statement. “It is not in the film. We are dealing privately with the family.”

Neither Moore nor his representatives would describe the nature or contents of the interview with Berg, who held staunch pro-war views.
