In 1946, eight months after the bombings of Hiroshima and Nagasaki, a team from the US army filmed a documentary about the Japanese defeat. Several reels were filmed in Japan, but upon arrival in the USA, and shortly after being reviewed by the authorities, reel 11004 was immediately classified as “defense secret”, remaining hidden until, six years ago, Mirabelle Fréville found it by chance, during a research for another movie at the National Archives in Washington. Beyond having found an important document unknown to the public, the filmmaker was particularly touched by the power of the images’ colors, in contrast to the black and white memory that we have collectively formed from Second World War movies such as Alain Resnais’ “Hiroshima mon amour”. From the dissection of these images, the deconstruction of the original footage and its re-editing, emphasized by an original musical score, the filmmaker offers “La Bobine 11004” as a reflection not only on the long known ominous effects of the atomic bomb, but also on the first censorship act in the history of nuclear energy. The director returns to Vila do Conde after having been a member of the festival jury in 1998. (MM)
