In an unused interview for Michael Moore's latest film, the American who was later beheaded in Iraq said he was concerned about security there as he prepared to seek work as an independent businessman, his family said Saturday.

Moore's crew shot the 16-minute interview with Nicholas Berg during an Iraqi business conference in Arlington on Dec. 4, said his brother, David Berg.

Nicholas Berg's decapitated body was found in Baghdad on May 8, and a video of his killing was posted on an Islamic militant Web site several days later.

Moore confirmed Thursday that he had footage of Berg -- shot for his film "Fahrenheit 9/11," which is critical of President Bush -- but said he would share it only with the family.

Moore sent copies of the footage to David Berg in New Jersey and sister Sara Berg in Virginia. Their parents will see the video after returning to their suburban home from vacation, David Berg said.

Sara Berg said her brother told Moore's crew he was nervous about his safety in Iraq.

"He recognized it was a concern, and he kind of pointed out that he'd worked in difficult situations before," Sara Berg said from her home in Virginia Beach. "It's definitely something that he didn't shrug off."

She said her brother seemed enthusiastic in the footage.

David Berg, speaking from his home outside Newark, said it was "weird seeing Nick talk" but described the interview footage as dry.

The interview, which was not conducted by Moore, centered on the technical work Berg hoped to find repairing radio transmission towers for his company, Prometheus Methods Tower Service. Berg, 26 when he died, also talks about humanitarian work he did in Uganda and Kenya.

"Nick seemed to be fairly conscious of using this thing to promote his business," David Berg said. "[The interviewer] does ask him at one point about the money and he said no one's denying there's money to be made. But it's very clear when you watch it, Nick knew he wasn't going to make a lot of money."

"Fahrenheit 9/11," which recently won the top prize at the Cannes Film Festival, accuses the Bush administration of stealing the 2000 election; overlooking terrorism warnings before Sept. 11, 2001; and fanning fears of more attacks to secure U.S. support for the Iraq war.
