I must confess to spending a great portion of my time watching documentaries about WWII, and I doubt there are many that I do not already own. I have listed a few that I would highly recommend if you are starting to collect them.
(1.) THE WORLD AT WAR 11 dvd set with over 26 hours, narrated by Sir Lawrence Olivier......A "must" for your collection!
(2.) WWII THE WAR IN EUROPE, with Walter Kronkite 3 dvds, over 11 hours. In depth look at both fronts (eastern and western) as well as previously unseen footage of the Warsaw uprising and other Partisan actions filmed by the freedom fighters themselves.
(3.) THE COLOR OF WAR, HISTORY CHANNEL..SETS #1 AND #2. Narrated by Peter Coyote, great color (real color, not "colorised") footage of AMERICAN troops. Covers everything from Basic Training to the War's end, and really taps into the feelings of our boys "Over There." 7 dvds
(4.) D-DAY, 60TH ANNIVERSARY COMMEMORATIVE EDITION 3-DVDS. Many Veteran interviews including Sgt. Leonard Lomell, 2nd Ranger Battalion, and major Dick Winters, 101rst Airborne.
(5) ROLLING THUNDER, THE STORY OF THE 3RD ARMORED DIV., FROM THE HISTORY CHANNEL. EXCELLENT chronicle of the famous "Spearhead Division" from WWII to Iraq. 1 dvd.
Okay, that'll do for starters. I could go on forever, as I am addicted to watching this great historical programs and discussing them with others afterward. Please feel free to add to my list! I must confess another thing....I am a "homer" when it comes to who's accounts I prefer, and I don't enjoy any that belittle American Commanders or Soldiers!
