Here is a rare 1969 documentary created by legendary producer Darryl F. Zanuck to commemorate the 25th anniversary of the D-Day invasion. Zanuck, of course, was the driving force behind Fox's 1962 epic blockbuster "The Longest Day", which had been a dream project for Zanuck. In this documentary, which is derived from a French print, Zanuck returns to the beaches with a film crew to discuss the monumental battle in which Allied forces from the U.S., Great Britain and Canada, along with Free French troops, defied formidable weather and heavy German resistance to breach Hitler's "Fortress Europe" and ultimately free the continent. The result, of course, was the beginning of the end of the Nazi regime and the eventual emergence of Germany as a free nation and thriving democracy. The documentary contains many clips from "The Longest Day". (Thanks to Cinema Retro reader Ted Marsowicz for alerting us to this video.)
