Barkhad Abdi
"Captain Phillips"
Role: Muse, a Somali fisherman turned pirate, who hijacks a merchant ship and holds the crew for ransom.
In his favor: A character at once menacing, naive, sympathetic and tragic. Holds his own against Tom Hanks. Cinderella story debut for an unknown.
Then again: Jared Leto has the kind of transformative role that voters gush over.
Daniel BrÜhl
"Rush"
Role: Real-life racer Niki Lauda, a shrewd survivor of the 1970s Grand Prix circuit.
In his favor: A surprising character arc, beginning as the apparent hero's antagonist, then overshadowing him.
Then again: The film has been a spinout in early awards-season competitions.
Bradley cooper
"American Hustle"
Role: FBI man Richie DiMaso, a lightweight aching to be taken seriously by his superiors, his mom and women generally.
In his favor: His impulsive comic energy and sheepish romanticism perfectly match the manic tone.
Then again: Cooper only curled his hair. Jared Leto wears a full wig and waxed his eyebrows off.
Michael Fassbender
"12 Years a Slave"
Role: Edwin Epps, a sadistic, ignorant but conflicted 1850s slaveholder.
In his favor: Fassbender delivers an intensive dose of fear sickness whenever he's on screen.
Then again: In a film some find difficult to watch, his scenes are the most awful. Jared Leto wears earrings.
Jared leto
"Dallas Buyers Club"
Role: Rayon, a vulnerable but business-savvy transvestite AIDS patient.
In his favor: Leto went full method, shedding 40 pounds and staying in character for the full production, even off-set. He's kind, silly, graceful and charming.
Then again: You're kidding, right?
jonah hill
"The Wolf of Wall Street"
Role: Donnie Azoff, a drug-fueled, incestuous vulgarian stock swindler and all-around fun guy.
In his favor: Shark-white teeth. Pastel sweaters. Lots and lots of Quaaludes.
Then again: Jared Leto wears painted nails and lipstick.
