Oyelowo, who starred as the chess teacher of Waligwa's character, Gloria, also paid tribute to the young star on Instagram. Sharing the same photo as Nyong'o, the actor wrote, "We mourn the loss of our beautiful Nikita Pearl Waligwa. She was a ball of light in @queenofkatwemovie and in life. Her battle with a brain tumor was humbling to witness. Her light will live on. 💔#rip"
Octavia Spencer and Olivia Munn reacted to the sad news in the comments section of Oyelowo's post. "Oh, Nooooo!!!!🙏🏽 praying for her loved ones!" Spencer wrote, while Munn shared multiple heart emojis.
According to the BBC, Waligwa was first diagnosed with a brain tumor in 2016. Mira Nair, the director of "Queen of Katwe," reportedly helped raise funds for Waligwa's treatment in India as Ugandan doctors said they didn't have the necessary equipment.
Waligwa recovered in 2017, but last year another tumor was found.
She was 15.
