Production on "Tora! Tora! Tora!" took three years to plan and prepare for the eight months of principal photography. The film was created in two separate productions, one based in the United States, directed by Richard Fleischer, and one based in Japan. The Japanese side was initially to be directed by Akira Kurosawa, who worked on script development and pre-production for two years. But after two weeks of shooting, he was replaced by Toshio Masuda and Kinji Fukasaku, who directed the Japanese sections.
