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.

As America enters the 250th year since the signing of the Declaration of Independence, director Ken Burns tells John Dickerson that the American Revolution was a "civil war" that became a "big world war by the end" and more.
