The trailer for the upcoming faith-based documentary about Johnny Cash has launched, depicting friends, family and Cash himself discussing his career.

Johnny Cash: The Redemption of an American Icon will release in theaters for only three nights: December 5, 6 and 7. Fathom is distributing it. Kingdom Story Company, the same company that produced I Can Only Imagine, American Underdog, I Still Believe, and Woodlawn, made it. Ben Smallbone directed it.

The film’s synopsis reads, “Arguably among America’s greatest ever entertainers, the late Johnny Cash rode his talent to the top of the music world, selling an estimated 90 million records, winning nearly 40 awards and being inducted into half a dozen music halls of fame. His 50-plus year career, however, also took him from the dizzying heights of professional acclaim to the depths of drug addiction and alcohol abuse, and the upcoming documentary, ‘Johnny Cash: The Redemption of an American Icon,’ will follow the Arkansas native’s journey.”

The film includes audio from recordings that have never been heard outside the Cash family. “There’s no lonelier place on earth for a man to be than separated from God,” Cash says in the film.

When asked if he regrets his troubled past, Cash says: “I forgave myself. When God forgave me, I figured I better do it, too.” Cash, who died in 2003, also puts his popularity in perspective: “It’s all fleeting, as fame is fleeting.”

The trailer includes interviews with his sister Joanne Cash Yates and his son John Carter Cash, Marty Stuart, Wynonna Judd, Jimmie Allen, Alice Cooper, Greg Laurie, Sheryl Crow and Tim McGraw. Cash was a “guy who is broken and knows he needs God,” Judd said.

Producer Jon Erwin said Cash “shaped the musical landscape.” “Behind the fame is the true story of a man who was haunted by his own inner demons and, through facing them, ultimately found an unshakable faith in God,” Erwin said. An unidentified voice in the trailer says Cash “wanted to be the biggest thing in the world, and he became the biggest thing in the world, and then he stepped back, and he said, ‘That’s not all there is.'”

“I think of all the documentaries made about my dad, he’d be most excited about this one,” said John Carter Cash. To learn more about ‘Johnny Cash: The Redemption of an American Icon,’ click here.
