Johnny Cash: The Man, His Music, His World tonight on P.O.V. on PBS

Robert Elfstrom's 1969 documentary on Johnny Cash airs tonight at 10pm on PBS's P.O.V. series.

From the P.O.V. website:

In this classic 1969 documentary, the Man in Black is captured at his
peak, the first of many in a looming roller-coaster career. Fresh on the
heels of his Folsom Prison album, Cash reveals the dark intensity and
raw talent that made him a country music star and cultural icon. Director
Robert Elfstrom got closer than any other filmmaker to Cash, who is
seen performing with his new bride June Carter Cash, in a rare duet
with Bob Dylan, and behind the scenes with friends, family and aspiring
young musicians. Johnny Cash: The Man, His World, His Music paints
an unforgettable portrait that endures beyond the singer’s 2003 death.

“Elfstrom’s film is a book of quiet revelations.”
— Matt Zoller Seitz, Time Out New York

“Robert Elfstrom’s magnificent 1969 documentary Johnny Cash: The Man,
His World, His Music ranks among the most comprehensive and effective
cinematic presentations of the late Cash’s persona and impact.”
—Ron Wynn, Nashville City Paper

The P.O.V. site has a great excerpt of Johnny and June Carter Cash singing a sweaty version of "Jackson," but since they don't seem to allow their videos to be embedded, here's Mark Romanek's masterful video of the Man in Black in his final year, covering NIN's "Hurt."
