Amy Adams
"Vice"
Role: Lynne Cheney, the culture warrior behind a rising politician.
In her favor: Lady Macbeth in a perfect Republican helmet of hair, Adams unleashes a ruthless resolve to whip her dissolute husband into shape and goad him to power. (G/S/B)
Then again: Nominated five previous times, Adams has been passed over for better work, including a similar role in "The Master."
Marina de Tavira
"Roma"
Role: Sofia, the overwhelmed matriarch of a boisterous Mexican family.
In her favor: She manages to be both maddeningly neglectful and achingly sympathetic. We can feel that, somewhere beneath that caustic exterior, a loving mother is struggling to emerge.
Then again: Foreign-language performances are a tough sell, as evidenced by her omission from rival award contests.
