Watch Johnny Cash: The Redemption of an American Icon

From his hardscrabble Arkansas upbringing to the heights of musical success, Johnny Cash - JR to his friends - was as unshakeable in his devotion as he was unsparing in his songwriting. This moving documentary, rooted in Cash's faith, tells the story of a man who knew tragedy from the earliest age, stared down the demons of addiction...and never lost sight of the light. Insightful commentary by Sheryl Crow, Tim McGraw, John Carter Cash, Johnny's sister Joanne Cash Yates, and more add depth and color to this uniquely American icon, who once said of himself, "Johnny's a nice guy, but sometimes Cash gets into trouble."
