The nominations for the 84th annual Academy Awards were announced earlier today by Academy of Motion Picture Arts and Sciences President Tom Sherak and actress Jennifer Lawrence, who was nominated for her work in Winter's Bone in 2010 and is starring in the upcoming action/adventure movie The Hunger Games.

Academy members from each of the branches vote to determine the nominees in their respective categories – actors nominate actors, film editors nominate film editors, etc. In the Animated Feature Film and Foreign Language Film categories, nominations are selected by vote of multi-branch screening committees. All voting members are eligible to select the Best Picture nominees.

All active and life members of the Academy are eligible to select the winners in all categories, although in five of them – Animated Short Film, Live Action Short Film, Documentary Feature, Documentary Short Subject and Foreign Language Film – members can vote only if they have seen all of the nominated films in those categories.

The ceremony for the Academy Awards for outstanding film achievements will be held on Sunday, February 26, 2012, at the Kodak Theatre at Hollywood & Highland Center in Hollywood, California.
