LOS ANGELES (AP) -- Iraq War thriller "The Hurt Locker" has won the best picture Oscar. Kathryn Bigelow won the best-director Academy Award for "The Hurt Locker."

Sandra Bullock and Jeff Bridges have won the lead-acting honors. Bullock won for her role as a wealthy woman who takes in a homeless future NFL star in "The Blind Side." Bridges won best-actor for his turn as a boozy country singer trying to clean up his act in "Crazy Heart."

Villainous roles snatched the supporting-acting prizes at the Academy Awards: "Precious" co-star Mo'Nique as a contemptible mother and "Inglourious Basterds" co-star Christoph Waltz as a sociable Nazi fiend.
