"There's no lonelier place on earth for a man to be than separated from God," Cash says in the film.

The documentary will also touch on Cash finding forgiveness in himself and changing his life around once he realizes that God has forgiven him before passing away in 2003.

"It's all fleeting, as fame is fleeting."

Previewed in the trailer are interviews with Cash's family among others, there will be his sister Joanne Cash Yates and his son John Carter Cash as well as 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," says Judd.

Producer Jon Erwin says Cash "shaped the musical landscape."

This film shows the ugly side of what fame can do to someone, Cash is one of those people but this documentary shows he was able to revitalize himself through Christ.

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.'"
