"A maggot that eats off the dead" – that's what the mother of a U.S. Air Force major killed in the Iraq thinks about filmmaker Michael Moore, who used footage from the man's Arlington Cemetery funeral in his anti-Bush movie "Fahrenheit 9/11."

Air Force Maj. Gregory Stone was killed in March 2003 when a grenade was thrown into his tent, allegedly by Sgt. Hasan K. Akbar, who is on trial for murder.

"It's been a big shock, and we are not very happy about it, to say the least," Kandi Gallagher, Stone's aunt and family spokeswoman, told the Washington Times.

"We are furious that Greg was in that casket and cannot defend himself, and my sister, Greg's mother, is just beside herself," Gallagher said. "She is furious. She called [Moore] a 'maggot that eats off the dead.'"

The video footage shows Stone's fiancée, Tammie Eslinger, kissing her hand and touching it to his coffin, the Times reported.

Gallagher says the family doesn't know how Moore got the footage, but is considering taking legal action against the director.

"Fahrenheit 9/11" opened June 25 in U.S. theaters and has brought in $80.1 million so far.
