There are a ton of people in the running for these categories. First, in the Supporting Actor category, Bill Murray should be considered a frontrunner for Olive Kitteridge. From Wolf Hall, both Damien Lewis and Jonathan Pryce are in the running, though they could also cancel each other out through vote splitting. Stephen Rea might get nominated for The Honorable Woman. Then we have the cast of American Horror Story: Freak Show, which Michael Chiklis. Finn Wittrock. Neil Patrick Harris. and John Carroll Lynch could all be considered contenders. Plus, there’s the supporting cast of Texas Rising, which includes Kris Kristofferson, Olivier Martinez, and Ray Liotta. Outside chances for Michael Kenneth Williams for Bessie, Michael Gambon for The Casual Vacancy, and Nick Nolte for Gracepoint.
I’d nominate Murray, Chiklis, Wittrock, Brian Cox for The Slap, and Williams.
For Supporting Actress, Monique is in play for Bessie, with Janet McTeer for The Honorable Woman nipping at her heels. Susan Sarandon is possible for the poorly reviewed Marilyn movie. There’s also Claire Foy for Wolf Hall, Zoe Kazan for Olive Kitteridge, and Regina King for American Crime. And of course, the American Horror Story gang, including Kathy Bates, Angela Bassett, Frances Conroy, and Sarah Paulson. Longer shots for Jacki Weaver for Gracepoint, Khandi Alexander for Bessie, and Cynthia Nixon for Stockholm Pennsylvania.
I’d go with Monique, Paulson, Bates, Michelle Fairley for 24: Live Another Day, and Thandie Newton for The Slap.
