In the impoverished Katwe neighborhood of the Ugandan capital, young Phiona Mutesi (Madina Nalwanga) did what she could to help her pragmatic mother Harriet (Lupita Nyong’o) provide for the family. Introduced to the game of chess, she proves to be a prodigy--and with the encouragement of her mentor (David Oyelowo) and in the face of her mother’s skepticism--her gift opens societal doors she once thought closed. Mira Nair’s colorful, compelling true-life opus also stars Martin Kabanza, Ivan Jacobo, Nicolas Levesque. 124 min.
