From slum girl to silver screen: Uganda's chess prodigy

Phiona Mutesi happened upon chess as a famished 9-year-old foraging for food in the sprawling and impoverished slums of the Ugandan capital.

"I was very hungry," says Mutesi, aged about 18.

Now a chess champion who competes internationally, her tale of triumph over adversity is being turned into a Hollywood epic with Oscar-winning Kenyan actress Lupita Nyong'o tipped to play her mother.
