For nearly two generations, he's been perhaps the foremost film documentarian of American history-and in this intriguing PBS portrait, the camera has been trained on Ken Burns himself. Shown on the road in pursuit of his projects as well as working and editing out of his primary and longtime home in Walpole, New Hampshire, insights are offered into a filmmaker's process and the living environment that shaped his values. 60 min. Widescreen; Soundtrack: English.
