Jessica Chastain, 35, in Zero Dark Thirty
Her role: Maya, an intense CIA officer who is dedicated to hunting down Osama bin Laden
Oscar history: Nominated for supporting actress as naive yet open-minded Southern belle Celia in 2011's The Help.
Why she might win:
As a rare woman to dominate an action thriller, Chastain's steely-eyed
determination is as riveting as that of any macho man, but with a
distinctly female sensibility.
Why she might lose: Controversies over the film's depiction of torture could work against her.
Jennifer Lawrence, 22, in Silver Linings Playbook
Her role: Tiffany, a feisty widow who carries plenty of her own baggage as she rocks Bradley Cooper's bipolar world.
Oscar history: Nominated
for best actress as Ree Dolly, a backwoods teen who must outwit her
unsavory Ozarks clan to save her mother and young siblings in 2010's Winter's Bone.
Why she might win: Lawrence has proven her star power in action fare like The Hunger Games.
But here she delights as a throwback to the kind of smart-mouthed
heroines that used to abound in screwball comedies decades ago.
Why she might lose: At her age, many other opportunities to collect gold will likely lie ahead.

Quvenzhane Wallis, 9, in Beasts of the Southern Wild
Hushpuppy, a 6-year-old living a nearly feral existence in the
Louisiana bayou, who endures alongside her mentally imbalanced father.
Oscar history: It starts today.
Why she might win: This untrained youngster's mesmerizing performance is a one-of-a-kind wonder that won't be repeated soon.
Why she might lose: The
youngest nominee ever in this category - a distinction previously held
by a then-13-year-old Keisha Castle-Hughes of 2003's Whale Rider - might have to wait until she ages into double digits to have a real shot at the prize.
Naomi Watts, 44, in The Impossible
Her role: Maria Belon, a British tourist at a Thai resort whose family is torn apart when the 2004 tsunami strikes.
Oscar history: Nominated for best actress as a widow who unknowingly falls for the recipient of her dead husband's heart in 2003's 21 Grams.
Why she might win: There's nothing like a beautiful actress suffering on screen to excite voters, and a soaked Watts did just that.
Why she might lose: The film has yet to strike a chord with most moviegoers.

Emmanuelle Riva, 85, in Amour
Her role: Anne,
an elderly music teacher, whose devoted husband tends to her needs in
their cloistered apartment as her health deteriorates.
Oscar history: The French legend is best known as the romantic lead of 1959's Hiroshima Mon Amour, which was nominated for a screenplay Oscar.
Why she might win:
As the oldest acting nominee ever in any category, Riva gives a master
class of nuanced acting with her devastating portrait of a dying woman
coping with her inevitable fate.
Why she might lose: Foreign-language performers are often are passed over.
