Tora! Tora! Tora! (1970) – Producer Darryl F. Zanuck had already made The Longest Day in 1962, dramatizing D-Day. He then decided to tackle another tale of World War II, telling the story of the attacks on Pearl Harbor. Helmed by Richard Fleischer (who directed the American scenes), Toshio Masuda and Kinji Fukasaku (who directed the Japanese scenes), the result is an epic film with a remarkable ensemble cast.
