As the U.S. prepares to celebrate its 250th anniversary, Ken Burns is releasing a deep look into the fight for American independence.

The documentarian will hold a live talk at Seattle's McCaw Hall on July 14, during which a sneak preview of the documentary will be shown.

Burns and "The American Revolution" co-director David Schmidt walk in Colonial Williamsburg. Burns says he does not take his self-appointed civic duty and his career immersed in wars lightly.
