The Great Atomic Film Cover-Up

Shooting the U.S. Military Footage

In early September, 1945, less than a month after the two bombs fell, Lt. McGovern -- who as a member of Hollywood's famed First Motion Picture Unit shot some of the footage for William Wyler's "Memphis Belle" -- had become one of the first Americans to arrive in Hiroshima and Nagasaki. He was a director with the U.S. Strategic Bombing Survey, organized by the Army the previous November to study the effects of the air campaign against Germany, and now Japan.

As he made plans to shoot the official American record, McGovern learned about the seizure of the Japanese footage. He felt it would be a waste to not take advantage of the newsreel footage, noting in a letter to his superiors that "the conditions under which it was taken will not be duplicated, until another atomic bomb is released under combat conditions."

McGovern proposed hiring some of the Japanese crew to edit and "caption" the material, so it would have "scientific value." He took charge of this effort in early January 1946, even as the Japanese feared that, when they were done, they would never see even a scrap of their film again.
