The civil war, the award-winning documentary from filmmaker ken burns, returns to pbs 12 years after its premiere. The landmark series, airing in its entirety with no content alteration, is rebroadcast complete with digitally remastered images and audio. The updated version takes advantage of new film-transfer, color-correction and audio-mixing techniques - every frame has been digitized and the sound remixed in stereo. The update also features a new introduction by burns, special interviews with shelby foote, stanley crouch and george will, and new behind-the-scenes material, including a side-by- side demonstration of the remastered footage. David mccullough narrates the series, which vividly portrays the terrible conflict that tore this country apart and defined the united states as a nation. Archival photographs and period paintings join newsreel footage of civil war veterans, live cinematography of battle sites, interviews with eminent historians and a chorus of voices reading from diaries, letters, speeches and newspapers of the era. The principal commentator is shelby foote, author of the three-volume ' the civil war: a narrative.'
