85. Jessica Chastain
Biggest accomplishment this year: Receiving an Academy Award nomination for Best Actress, for Zero Dark Thirty
She's only been acting professionally for five years, but Jessica Chastain's stats are already staggeringly impressive. The redheaded acting queen has two Academy Award nominations, a pair of BAFTA nods, two Golden Globe noms, and, get this, 38 critics' groups award victories.
And here's the scary part: She's not even in her career's prime yet. Only 36, the Zero Dark Thirty star is well on her way to becoming the next Meryl Streep, assuming she wants to go that route. As evidenced by her turn as Goth chick in this year's horror hit Mama, she's not against sidestepping Oscar bait for the occasional genre exercise.
