Tora! Tora! Tora! is the Japanese signal to attack and this movie meticulously re-creates the attack on Pearl Harbor and the events leading up to it. Opening scenes contrast the American and Japanese positions. Japanese imperialists decide to stage the attack; top U.S. brass ignore its possibility. Intercepted Japanese messages warn of it but never reach President Roosevelt's desk. Radar warnings are disregarded. Even the capture of a Japanese submarine inside Pearl Harbor before the attack goes unreported. Ultimately, the 'Day of Infamy' arrives in the most spectacular, gut-wrenching cavalcade of action-packed footage ever. It's the most dazzling re-creation of America's darkest day; and some of her finest hours.
