Tora! Tora! Tora! - Production

Production

Veteran 20th Century Fox executive Darryl F. Zanuck, who had earlier produced The Longest Day (1962), wanted to create an epic that depicted what "really happened on December 7, 1941", with a "revisionist's approach". He believed that the commanders in Hawaii, General Short and Admiral Kimmel, though scapegoated for decades, provided adequate defensive measures for the apparent threats, including relocation of the fighter aircraft at Pearl Harbor to the middle of the base, in response to fears of sabotage from local Japanese. Despite a breakthrough in intelligence, they had received limited warning of the increasing risk of aerial attack. Recognizing that a balanced and objective recounting was necessary, Zanuck developed an American-Japanese co-production, allowing for "a point of view from both nations." He was helped out by his son, Richard D. Zanuck, who was chief executive at Fox during this time.

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.

Richard Fleischer said of renowned director Akira Kurosawa's role in the project:

Well, I always thought that even though Kurosawa was a genius at film making and indeed he was, I sincerely believe that he was miscast for this film, this was not his type of film to make, he never made anything like it and it just wasn't his style. I felt he was not only uncomfortable directing this kind of movie but also he wasn't used to having somebody tell him how he should make his film. He always had complete autonomy, and nobody would dare make a suggestion to Kurosawa about the budget, or shooting schedule, or anything like that. And then here he was, with Darryl Zanuck on his deck and Richard Zanuck on him and Elmo Williams and the production managers, and it was all stuff that he never had run into before, because he was always untouchable. I think he was getting more and more nervous and more insecure about how he was going to work on this film. And of course, the press got a hold of a lot of this unrest on the set and they made a lot out of that in Japan, and it was more pressure on him, and he wasn't used to that kind of pressure.

Larry Forrester and frequent Kurosawa collaborators Hideo Oguni and Ryuzo Kikushima wrote the screenplay, based on books written by Ladislas Farago and Gordon Prange of the University of Maryland, who served as a technical consultant. Numerous technical advisors on both sides, some of whom had participated in the battle and/or planning, were crucial in maintaining the accuracy of the film. Minoru Genda, the man who largely planned and led the attack on Pearl Harbor was an uncredited technical advisor for the film.

The "Japanese" aircraft carrier was the Anti-Submarine carrier USS Yorktown (CVS-10). The Japanese A6M Zero fighters, and somewhat longer "Kate" torpedo bombers or "Val" dive bombers were heavily modified RCAF Harvard (T-6 Texan) and BT-13 Valiant pilot training aircraft. The large fleet of Japanese aircraft was created by Lynn Garrison, a well-known aerial action coordinator, who produced a number of conversions. Garrison and Jack Canary coordinated the actual engineering work at facilities in the Los Angeles area. These aircraft still make appearances at air shows.

A Boeing B-17 Flying Fortress’s actual crash landing during filming, a result of a jammed landing gear, was filmed and used in the final cut. A total of five Boeing B-17s were obtained for filming. Other U.S. aircraft used are the Consolidated PBY Catalina and, especially, the Curtiss P-40 Warhawk (two flyable examples were used). Predominately, P-40 fighters are used to depict the U.S. defenders with a full-scale P-40 used as a template for fiberglass replicas (some with working engines and props) that were strafed and blown up during filming. Fleischer also said a scene involving a P-40 model crashing into the middle of a line of P-40s was unintended, as it was supposed to crash at the end of the line. The stuntmen involved in the scene were actually running for their lives.

The flying scenes were complex to shoot, and can be compared to the 1969 film Battle of Britain. The 2001 film Pearl Harbor would contain cut scenes from both films. The carrier entering Pearl Harbor towards the end of the film was in fact the Iwo Jima-class amphibious assault ship USS Tripoli (LPH-10), returning to port. The film contains second unit and miniature photography, shot by Ray Kellogg.

Noted composer Jerry Goldsmith composed the film score. Robert McCall painted several scenes for various posters of the film.
