Operation Overlord - Planning the D-Day Invasion

This Universal Newsreel (really more like a documentary) provides primary-source information on the build-up to D-Day and take us to the initial Normandy landings. 

The producer of the film (Universal City Studios) gives us this background:  "Universal Newsreel, in full co-operation with the War Department, presents official pictures of the final military preparations for the launching of D-Day. A host of nations engage in the huge task. The invasion, in truth, is a United Nation's effort."
