In this classic 1969 documentary, Johnny Cash 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 a portrait that endures beyond the singer's 2003 death.
