James Cameron's "Avatar" and Kathryn Bigelow's "The Hurt Locker" led all films with nine Oscar nominations as contenders for the 82nd Academy Awards were announced Tuesday morning at the Samuel Goldwyn Theater in Beverly Hills.

The Best Picture nominees also included "Inglourious Basterds," with eight nominations, and "Up in the Air" and "Precious," with six apiece. Rounding out the category, which the Academy expanded from five to 10 nominees for the first time in more than 60 years, were "District 9" (four noms), "The Blind Side" (two), "An Education" (three), "A Serious Man" (two) and animated feature "Up" (five).

Best Actor and Best Actress nominees include Jeff Bridges ("Crazy Heart"), George Clooney ("Up in the Air"), Meryl Streep ("Julie & Julia") and Sandra Bullock ("The Blind Side"). In the Supporting Actor and Supporting Actress Categories, favorites Christoph Waltz ("Inglourious Basterds") and Mo'Nique ("Precious") led a lineup that also includes Woody Harrelson, Anna Kendrick and Vera Farmiga.

"Avatar" and "The Hurt Locker" are considered the Best Picture race's two frontrunners. "Avatar" won the Golden Globe for Best Movie - Drama and Best Director, but "The Hurt Locker" has picked up the lion's share of awards so far this season, including the Critics Choice Movie Award and crucial wins at the Producers Guild and Directors Guild Awards.
