SAG Winner Predictions: Best Actress in a Supporting Role

The competition: Patricia Arquette’s protective mother (Boyhood),), Keira Knightley’s bright math whiz (The Imitation Game), Emma Stone’s angst-filled daughter (Birdman), Meryl Streep’s charismatic witch (Into the Woods), and Naomi Watts’ pregnant prostitute (St. Vincent).

For your information: Meryl Streep has a formidable history here – nine previous film nominations and one previous TV bid, which she won, along with a film award for “Doubt” in 2008. Watts has two previous film nominations, for “21 Grams” and “The Impossible,” and Arquette contended three times for “Medium.” Arquette, Knightley, and Stone are all nominated as part of their ensembles, and Watts is nominated as part of the “Birdman” cast. Arquette won the Golden Globe, though Watts wasn’t nominated there.

Who should win: Stone

Who will win: It should still be Arquette.
