A Led Zeppelin documentary from the team behind the PBS doc American Epic is now in post-production and will be offered for sale at the upcoming Cannes Film Festival.

Directed by Bernard MacMahon, the film features new interviews with Jimmy Page, Robert Plant and John Paul Jones plus archival interviews with John Bonham. The story will be told through their four voices and no outsiders.

"When I saw everything Bernard had done both visually and sonically on the remarkable achievement that is American Epic, I knew he would be qualified to tell our story,” said guitarist Page.

Allison McGourty, MacMahon, Duke Erikson and Ged Doherty are the film’s producers. CAA has the rights to the U.S.; Altitude is selling it internationally, according to a report in Variety.

Plant felt the filmmakers were the right people to do the job after he saw their work with blues and country musicians from the 1920s and ‘30s such as the Memphis Jug Band in American Epic. “Seeing Will Shade, and so many other important early American musicians, brought to life on the big screen in American Epic inspired me to contribute to a very interesting and exciting story.”

The filmmakers say deciphering the lyrics of Charley Patton was an easier task that fully comprehending what "a bustle in your hedgerow" is.
