20 Best Movie Performances Of 2017

4. Jessica Chastain – Molly’s Game

Jessica Chastain adds another firecracker performance to her incredible repertoire with her turn as Olympic skiier-turned-underground-poker-princess Molly Bloom.

Aided by typically fantastic work from writer-director Aaron Sorkin, Chastain rattles through Sorkin's machine gun-fire dialogue with an intense ferocity that's rarely seen, cementing the wit, intellect and searing, empowering sexuality that makes Molly a towering type-A personality.

Playing opposite a fantastic ensemble cast, best of all Idris Elba, this is most certainly one of Chastain's best performances to date, and yet further proof that she's one of the very best actresses working today.
