A forthcoming documentary on late grunge-era rock guitarist and singer Chris Cornell has been given the green light by the Cornell estate to go into production. The project, which has yet to be given an official title, will be produced by Hollywood actor Brad Pitt and acclaimed director Pete Berg (Friday Night Lights, Lone Survivor). Cornell’s widow, Vicky Cornell, will also come on to the project as a producer. The upcoming film is the first official documentary approved by Cornell’s estate since the Soundgarden singer killed himself following a solo concert in Detroit on May 18, 2017.

Pitt was one of the many notable entertainers in attendance at the “I Am the Highway: A Tribute to Chris Cornell” concert event at The Forum in Los Angeles last month. Pitt helped welcome Cornell’s daughter Toni and Ziggy Marley to the stage to perform a lovely duet cover of Bob Marley & The Wailers‘ 1980 ballad, “Redemption Song”. With the confirmation of the documentary on Thursday, there’s a pretty good chance that Pitt’s appearance at the all-star event means that footage of the concert could very well end up in the final cut of the film.

The report did not state who, if any, of Cornell’s former bandmates, friends, and industry colleagues may appear as interview subjects in the upcoming film. Considering the fact that Cornell’s family is on board in helping to produce the film, fans should also expect to be presented with never-before-seen archival footage of the famous rock singer prior to his untimely death.

The upcoming film is the most recent of numerous tributes which have come into existence in the nearly two years since Cornell passed. A statue of Cornell was recently erected in his hometown of Seattle outside of one of the city’s museums. The Cornell estate also recently helped to plan and release a 62-track, 4-disc box set containing 11 previously-unreleased recordings last November.
