1.
Jessica Chastain as Lucille Sharpe
Crimson Peak
For bringing back Kathy Bates' Annie Wilkes in the form of Lucille Sharpe, a fierce and insecure ghostie wanting Mia Wasikowska dead, and Chastain proved yet again that she can act any role, may it be antagonist or protagonist.
2.
Cynthia Nixon as Gail White
James White
For her haunting performance in James White. She made the movie worth watching despite its depressing content.
3.
Jennifer Jason Leigh as Daisy Domergue / The Prisoner
The Hateful Eight
For outshining the stars of The Hateful Eight, and for basically being the MVP of the film. Her Jim Jones at Botany Bay is beautiful.
4.
Joan Allen as Nancy Newsome
Room
For leaving a mark in Room despite her minimal airtime. Her I love you scene with Jacob Tremblay wrecked me.
5.
Mya Taylor as Alexandra
Tangerine
For impressively exuding passion and elegance despite the trashy nature of her character's surroundings.
