D-Day wasn't just fought at Omaha Beach, though Hollywood may have thought so before The Longest Day. D-Day involved a cast of thousands, and it took producer Darryl Zanuck, five screenwriters, four directors, and three hours just to bring it to the big screen. In fact, Spielberg cribbed large chunks of this film verbatim for Saving Private Ryan. Ultimately, Ryan is the better picture, but The Longest Day shows you more of the story (and it's closer to reality), from the paratrooper force sent in as a diversion, to a half-dozen beach battles, to the French Resistance and how they helped. Aside from a great war tale, Day also marks what must be the only film where you can see John Wayne, Henry Fonda, Fabián, Sal Mineo, Eddie Albert, Red Buttons, Peter Lawford, and Sean Connery all fighting the same war. And on the same side, no less.
