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.
