CHRISTIAN BALE, "The Fighter"
In his favor: To play a drug-addled ex-boxer, he effected shocking weight loss, thinned hair, junkie jitters and a Massachusetts accent thick as chowdah. This is acting with a capital A.
Then again: Bale hogged the mike in his Golden Globes acceptance speech. Nobody wants that again.
JOHN HAWKES, "Winter's Bone"
In his favor: He plays a terrifying bad man is if he were a real person, not a Mortal Kombat villain. You sense his pain even as every glance spits knives.
Then again: His powerful, internalized acting is a far cry from Bale's hyperventilating performance. Squeaky wheel gets the Oscar, probably.
JEREMY RENNER, "The Town"
In his favor: His scary roughneck bank robber sizzles with the glee of reckless abandon. Crime might not pay, but he shows how liberating it can be.
Then again: There's a bigger, meatier role as a nutso Baahston-area loose cannon this year, and the guy in that part also plays Batman.
MARK RUFFALO, "The Kids Are All Right"
In his favor: He nails a very specific character type, the gauche California playboy. His laddish Lothario upsets the equilibrium of a lesbian household, but grounds the movie.
Then again: He's dismissed from the film abruptly. A good exit always helps.
