It's been more than 60 years since the United States dropped an atomic bomb on Hiroshima, Japan, on August 6, 1945.
Three days later another atomic bomb fell on Nagasaki, bringing an end to World War Two.
Scholars, policy makers and citizens have been debating the merits of the decision ever since.
But despite the enormity of the event and the passage of time…many of us know very little about how those bombs affected the lives of the people on the ground.
That's what motivated Academy Award-winning filmmaker Steven Okazaki to create his new documentary White Light/Black Rain: The Destruction of Hiroshima and Nagasaki.
The film will premiere on HBO on August 6.
But Okasaki is in town tonight to present his work at a special screening co-sponsored by the Chicago Council on Global Affairs.
White Light/Black Rain features in depth interviews with survivors of the bombings in Hiroshima and Nagasaki along with rarely seen archival footage.
He says his inspiration for it all began more than two decades ago.
White Light, Black Rain will air on August 6 on HBO.
