Rest in peace, Nikita Pearl Waligwa.
Waligwa was first diagnosed with a brain tumor in 2016, and her Queen of Katwe family, including director Mira Nair, reportedly mobilized to get her treatment in India. She made a recovery in 2017, but the tumor reportedly returned last year.
The actress played Gloria in Queen of Katwe, which told the true story of Phiona Mutesi (Madina Nalwanga), a chess prodigy rising from a Ugandan slum, going on to compete in international tournaments. Gloria was a friend of Phiona's, who explained the rules of chess to her. Lupita Nyong'o also starred in the 2016 Disney movie as Phiona's mother, while David Oyelowo starred as her chess teacher.
