The new movie Queen of Katwe has a familiar theme: It's the real-life story of a girl from the slums who discovers an unlikely talent (chess) and becomes an unlikely champion.

Actor Jeffrey Tambor plays Maura and has just won a second Emmy for his performance. "When those roles come along, you don't run away," he tells NPR's Kelly McEvers. "It's a perfect role, you know? I thought I was gonna do Lear, but I'm gonna do Maura."
