Rebecca Rubin Film and Media Reporter Christopher Nolan’s historical epic “Oppenheimer,” about the creation of the atomic bomb during World War II, is preparing for a massive global debut next month. As of now, though, the film’s distributor Universal has yet to announce when — or if — it will premiere in Japan. A spokesperson for the studio says “plans have not been finalized in all markets.” Universal is releasing the $100 million-budgeted “Oppenheimer” in the U.S. and much of the rest of the world on July 21. The situation in Japan is complicated given the film’s subject matter and the devastation the bombs wrought on the country. “Oppenheimer” centers on American theoretical physicist J. Robert Oppenheimer (played by Cillian Murphy), who led the efforts to build the weapons of mass destruction that ended the war. Approximately 200,000 Japanese civilians died after two atomic bombs were dropped in 1945 over the cities of Hiroshima and Nagasaki. Though the movie’s focus may not be enough to prevent the country from playing “Oppenheimer” in its theaters, if it does secure a release date, it’s not clear that Japanese moviegoers will be interested in seeing a film about the topic.
