"Tora! Tora! Tora!", finally released to unenthusiastic reviews in September 1970, was, as Donald Richie put it, an "almost unmitigated tragedy" in Kurosawa's career. He had spent years of his life on a logistically nightmarish project to which he ultimately did not contribute a foot of film shot by himself. (He had his name removed from the credits, though the script used for the Japanese half was still his and his co-writers'.) He became estranged from his longtime collaborator, writer Ryuzo Kikushima, and never worked with him again. The project had inadvertently exposed corruption in his own production company (a situation reminiscent of his own movie, "The Bad Sleep Well"). His very sanity had been called into question. Worst of all, the Japanese film industry—and perhaps the man himself—began to suspect that he would never make another film.
