"20 Days in Mariupol": Meet the Ukrainian Filmmaker Who Risked His Life Documenting Russian Siege

Ukrainian Associated Press journalist Mstyslav Chernov joins us for an in-depth interview about how he and others risked their lives to document the Russian invasion. He is the director of the new documentary, 20 Days in Mariupol," which has just premiered at the Sundance Film Festival. It tells the story of how Chernov and his colleagues documented the first three weeks of Russia's siege of the strategic eastern port city of Mariupol, even after many international journalists had fled. The whole city spiraled down into complete chaos. People were in shock, in panic. They didn't know what to do," says Chernov, whose team was helped by locals in evading Russian soldiers and later escaping the city with their footage. The film is a co-production by the Associated Press and PBS Frontline.
