LOS ANGELES — Of the 89 documentary films eligible for Oscar consideration this year, 15 were selected for a short list of potential nominees. And Michael Moore's "Capitalism: A Love Story" wasn't one of them.

The Academy of Motion Picture Arts and Sciences announced the 15 titles Wednesday.

Some of the year's most popular documentary features were overlooked, including Moore's R-rated film, which was praised by critics and earned more than $14 million at the box office.

Also omitted from Oscar consideration was the well-reviewed Mike Tyson documentary "Tyson," the rock-doc "It Might Get Loud," and the story of Vogue magazine and its editor-in-chief, "The September Issue."

The short list of films is determined by a committee of members of the academy's documentary branch. They watch all eligible contenders and vote for their favourites by secret ballot. The top vote-getters make the short list of potential nominees.

The selections this year are "The Beaches of Agnes," "Burma VJ," "The Cove," "Every Little Step," "Facing Ali," "Food, Inc.," "Garbage Dreams," "Living in Emergency: Stories of Doctors Without Borders," "The Most Dangerous Man in America: Daniel Ellsberg and the Pentagon Papers," "Mugabe and the White African," "Sergio," "Soundtrack for a Revolution," "Under Our Skin," "Valentino The Last Emperor" and "Which Way Home."
