On the 40th anniversary of Hiroshima, Jon Else's powerful documentary on the human beings who developed the first nuclear weapons could not be more timely. Investigating the enigmatic personality and politics of the "father of the atomic bomb," Oppenheimer, the film takes us into the military boardrooms of Washington D.C., the battlegrounds of World War II, the aftermath of Hiroshima, and the eerie wilderness of Northern New Mexico, where the Manhattan Project exploded into reality for the first time. Jon Else and co-writers David and Janet Peoples weave together recently declassified government footage with the memories of surviving participants in the Oppenheimer story. The result is a drama of the personal, political, and moral forces that ushered us into the nuclear age. The Day After Trinity was funded in part by the California Council for the Humanities.
