America's preeminent documentary filmmaker Ken Burns, the guy that made the Civil War must-see viewing, is hard at work on a new project. PBS will broadcast Ken Burns' The National Parks: America's Best Idea in Fall 2009. In 12-hours, divided over six episodes, Burns will explore the places like Yellowstone, the Smoky Mountains, Yosemite, Mount Rushmore, et al, as well as the people who were instrumental in the creation of these landmarks.
