Jessica Chastain bested Olivia Colman ("The Lost Daughter"), Penelope Cruz ("Parallel Mothers"), Nicole Kidman ("Being the Ricardos") and Kristen Stewart ("Spencer") to win the prize.
Jessica Chastain on Sunday took home the Oscar for best actress, a reward for her remarkable physical transformation into a larger-than-life US televangelist in "The Eyes of Tammy Faye."
Chastain, 45, won over Academy voters with a performance that saw her don complex prosthetics, wigs and layers of Tammy Faye Bakker´s trademark heavy makeup every day on set in order to embody the late singer-turned-minister and LGBTQ activist.
She bested Olivia Colman ("The Lost Daughter"), Penelope Cruz ("Parallel Mothers"), Nicole Kidman ("Being the Ricardos") and Kristen Stewart ("Spencer") to win the prize.
