`Locker’ gets best-picture Academy Award; Bigelow first female director to win Oscar

LOS ANGELES -- Academy Awards voters are expected to go very big or very small on their best-picture winner at Sunday's Oscars.

The two favorites in the expanded field of 10 best-picture nominees are the as-big-as-it-gets blockbuster "Avatar" and the critical darling "The Hurt Locker," which drew a tiny fraction of the audience its mammoth competitor pulled in.

Either movie would represent a first at the Oscars. James Cameron's "Avatar" would be the only science-fiction film ever to take home the best-picture prize. While war films have done well at the Oscars, Kathryn Bigelow's "The Hurt Locker" would be the first winner centered on the war on terror, a subject that has stirred little interest among movie audiences shell-shocked by news coverage of Iraq and Afghanistan.
