In this special bonus episode, we're talking with the co-directors of the new Ken Burns documentary, Henry David Thoreau.

Thoreau has been called the patron saint of early environmental thought in the U.S., from his transcendentalist writings of the mid-19th century to his decision to live a secluded life at a cabin on Walden Pond in Massachusetts.

The three-part film, now streaming on pbs.org, the PBS app, and on Prime Video, examines Thoreau not just through the lens of American history, but it also asks what his work means to us in our current era.

The film was directed by brothers Erik Ewers and Christopher Loren Ewers, both frequent collaborators with Ken Burns, who is an executive producer along with Don Henley.

The Allegheny Front's Reid Frazier spoke with the Ewers brothers about the film.
