John welcomes acclaimed documentarian Ken Burns to discuss his latest PBS magnum opus, “The American Revolution.” Burns recounts the 10-year gestation of the six-part, 12-hour series, culminating with its fortuitous (but entirely coincidental) debut on the eve of the U.S. Semiquincentennial; how he assembled the remarkable array of Hollywood stars—Tom Hanks, Meryl Streep, Morgan Freeman, and dozens more—who voice the story’s key historical figures; and the case for George Washington as the revolution’s indispensable man, without whom America would not exist. Burns also reveals the five (yes, five) embryonic series on which he’s currently at work.
