Johnny Cash Doc in the Works From Frank Marshall

Frank Marshall is set to make a documentary about the music icon, Johnny Cash.

The new documentary will be directed by Thom Zimny, who also directed several Springsteen documentaries as well as HBO upcoming Film Elvis Presley: The Searcher.

The news of the still untitled new documentary came just one day before the 50th anniversary of Cash’s famous concert at Folsom Prison. The Cash doc will explore Cash’s music and biography through the famous prison concert, where the singer warned his audience not to say “hell or s**t” because Columbia Records was going to put it out on vinyl. That concert was the basis for his triple-platinum-selling album, Johnny Cash at Folsom Prison.

“While the linear narrative of the Folsom Prison performances will anchor our film, each song in the set list will open a door into a nonlinear presentation of Cash’s emotional, musical and personal development,” said Zimny in a statement.

The music icon was already featured in a 2015 biopic portrayed by Joaquin Phoenix, directed by James Mangold.

The documentary will have the full support of the Cash estate.
