Atomic Cover-Up

“Very powerful.” — Alex Gibney, Academy Award-winning director of numerous films, including Enron, Going Clear and Taxi to the Dark Side

“What a great film–and original concept. Fantastic. One hundred percent something to watch.” — Rod Lurie, director of The Outpost, Straw Dogs, The Contender and other movies

“So moving, disturbing and important.”   –Alex Winter, director of The Panama Papers, Show Biz Kids and other films.

GREG MITCHELL (writer/director/co-producer) //// After writing a dozen books, I have just completed writing and directing my first film, Atomic Cover-up. It was, one might say, thirty years in the making, and partly based on my book of the same title. It exposes the decades-long suppression by the U.S. of the most shocking, revealing important footage shot in Hiroshima and Nagasaki after the atomic bombings, by the top Japanese newsreel team and an elite American military crew (the chief cameraman had shot Akira Kurosawa’s first feature). If shown to Americans then this footage, many hours in length, might have curbed the nuclear arms race. The film, over fifty-two minutes in running time, has already been picked up by an international distributor and we will also be entering it in film festivals in the coming year. Suzanne Mitchell is co-producer. Rob Burgos edited it and Charlie Seaborn composed an original score. The advisers are Alex Gibney, Alex Winter, Markus Nornes and Martin J. Sherwin.

More Early Praise

“A very interesting film with a very important message, and the images are really horrifying.” –Patrick Vollrath, Academy Award-nominated director of 7500.

“Incredibly powerful and important.” –Martin J. Sherwin, Pulitzer Prize-winning co-author of American Prometheus, biography of J. Robert Oppenheimer

“Chilling.” — Sharon Grimberg, director of McCarthy and producer of dozens of other films for PBS’ American Experience, winner of three primetime Emmys

“The film is incredibly good. I was very moved by the story and by its urgency.” — Lyn Goldfarb, producer of Academy Award-nominated With Babies and Banners and director of numerous films.

“Great film!” — Anthony Weller, author of First Into Nagasaki about his father whose newspaper reports were censored and disappeared for 60 years.

“An important work, one that’s essential education for a generation with less and less familiarity with the horror of nuclear weapons. A major contribution to our collective memory.” — Daniel M. Gold, New York Times film reviewer, 2009-2017.

“Arresting and fascinating—horrifying all over again.” –Nicholson Baker, award-winning author of Human Smoke: The Beginnings of World War II, and other books.

“Greg Mitchell has been a leading chronicler of Hiroshima and Nagasaki, and American behavior toward them. Now he makes use of key interviews and documents to record an extremely important part of atomic bomb history that deserves far more attention today.” –Robert Jay Lifton, author of Death in Life (winner of the National Book Award) and other acclaimed books.

C-SPAN Special

C-SPAN recently televised a half-hour special about Atomic Cover-up and the footage that it is based on, which they made use of. The program aired about a dozen times to mark the 75th anniversary of the atomic bombings. It also briefly explored my related book, The Beginning or the End, on how Truman and the military sabotaged the first movie on this subject, from MGM, in 1946. You can now view the C-SPAN special it via their site.

The Story: Secrecy and Suppression

In the weeks following the atomic attacks on Japan in 1945, which killed over 200,000, the vast majority of them civilians, and then for decades afterward, the United States engaged in airtight suppression of all film shot in Hiroshima and Nagasaki after the bombings. This included footage shot by an elite U.S. Army crew and Japanese newsreel teams. In addition, for many years, all but a handful of newspaper photographs were seized or prohibited not only in the United States, but also in occupied Japan.

Meanwhile, the American public only got to see the same black and white images: a mushroom cloud, battered buildings, a devastated landscape. The true human costs–a full airing of the bomb’s effects on people –were kept hidden. The writer Mary McCarthy declared that Hiroshima had already fallen into “a hole in history.”  The public did not see any of the newsreel footage for 25 years, and the U.S. military film remained hidden for more than three decades. (The story is told in full in my book Atomic Cover-up.)

In fact, the Japanese footage might have disappeared forever if the newsreel team had not hidden one print from the Americans in a ceiling. The color U.S. military footage was not shown anywhere until the early 1980s, and has never been fully aired. It rests today at the National Archives in College Park, Md. When that footage finally emerged, I spoke with and corresponded with the man at the center of this drama: Lt. Col. (Ret.) Daniel A. McGovern, who directed the U.S. military film-makers in 1945-1946, managed the Japanese footage, and then kept watch on all of the top-secret material for decades.

McGovern (who is pictured in Nagasaki in the phtograph at the top of his site) observed that, “The main reason it was classified was…because of the horror, the devastation.” I also met and interviewed one top member of his military crew, Herbert Sussan,who had fought for years to get the footage aired widely in America, and interviewed some of the hibakusha (bomb survivors) who appear in the footage.  Those accounts, and the reports by several members of the Japanese newsreel team, form the center of Atomic Cover-Up.     The fllm includes footage never before seen and segments that have been aired previously are presented for the first time in vivid 4K.

Here is the first trailer, but please note this is not our narrator nor narration, which is quieter and based on the actual filmmakers, Japanese and American:
