Jennifer Lawrence ("Silver Linings Playbook") -- Lawrence plays a manic widow on the verge of a nervous breakdown who exorcises her demons ballroom dancing. Not only does she look great in leotards, but also she's funny and fierce and has mad chemistry with Bradley Cooper's bipolar, brokenhearted cutie in David O. Russell's Oscar-bound dramedy. Add in her monster hit "The Hunger Games" (OK, I wish she'd get nominated for that!) and her previous Oscar nom for "Winter's Bone," and you get frontrunner.
