10:45 p.m.: Michael Moore Stirs Passions at Oscars

Oscar experienced its first explosive moment when Best Documentary Oscar winner Michael Moore -- only seconds after receiving a standing ovation for his "Bowling for Columbine" -- was roundly jeered by the crowd inside the Kodak Theatre for his outspoken attack on President Bush.

Moore brought up his fellow nominees to the stage with him, he said, because they all stood in solidarity and were fans of nonfiction. Moore then said that none of them could support "a fictitious president who won a fictitious election and has led us into a fictitious war."

"We are against this war, Mr. Bush," Moore tried to shout above a chorus of boos. "Shame on you."

After Moore left the stage, host Steve Martin said, "The Teamsters are helping Michael Moore into the trunk of his limo."

Julianne Moore (a vision in green) received a rousing ovation when she entered to present the Oscar for Sound, which went to "Chicago" -- its fourth win of the night. So far, it has also copped the gold for Art Direction, Costume Design and Supporting Actress Catherine Zeta-Jones.

"The Lord of The Rings: The Two Towers" took its second Oscar for Sound Editing, having won for Visual Effects earlier in the evening.

"Frida" also has two Oscars in its fold, for Makeup and for Music (Original Score). The film biography concerns the great Mexican artist Frida Kahlo -- who said, "I don't paint my dreams, I paint my reality" -- and was a labor of love for Best Actress nominee Salma Hayek.

Hayek, considered a dark horse in that race, did present the Best Foreign Language Film Oscar, which went to Germany's "Nowhere in Africa," about a Jewish family finding refuge from the Nazis on the Dark Continent.

"Y Tu Mama Tambien"'s boyish young star, Gael Garcia Bernal, made, until that point, one of the relatively few references to the war in Iraq when, introducing the Best Song nominee from "Frida," "Burn It Blue," said it was a shame that Kahlo was no longer with us, so that she could speak out against the war.

Presenter Julie Andrews -- 1964's Best Actress for "Mary Poppins" -- received a standing ovation when she appeared onstage to introduce a film-clip montage of musical moments from past Oscarcasts. Ethel Merman monopolized the seemingly pointless montage with the anthem, "There's No Business Like Show Business."

Afterward, host Steve Martin explained, "I'm sorry I was late. I was backstage trying to convince Jennifer Lopez that the best way to remove duct tape was with saliva."

J.Lo -- sitting in the audience with fiancé Ben Affleck -- flashed her beau a puzzled look and then both shrugged their shoulders.
