This movie was produced as a joint Japanese-American venture. The acting by both casts is excellent, and the Japanese dialogue which takes up much of the action is well translated in the sub-titles, which are not so obtrusive as to interfere with the action. Filming is excellent, and the main irony of the history of Pearl Harbor, that not only was the US officially notified by the Japanese after the attack had commenced but that the US intelligence itself was not communicated to those in power, comes over clearly. This movie has generally been underrated: I give it full marks.
