2015 marks the Grateful Dead’s 50th anniversary and, to celebrate the occasion, they plan to release a career-spanning documentary directed by Amir Bar-Lev, with Martin Scorsese among the producers.

The filmmakers say that their as-yet-untitled film will include never-before-seen performance & backstage footage, as well as new interviews with surviving members Mickey Hart, Bill Kreutzmann, Phil Lesh, and Bob Weir, and other characters from the Dead universe.

“Millions of stories have been told about the Grateful Dead over the years. With our 50th Anniversary coming up, we thought it might just be time to tell one ourselves and Amir is the perfect guy to help us do it,” the band said in a statement. “Needless to say, we are humbled to be collaborating with Martin Scorsese. From The Last Waltz to George Harrison: Living In The Material World, from Bob Dylan to the Rolling Stones, he has made some of the greatest music documentaries ever with some of our favorite artists and we are honored to have him involved. The 50th will be another monumental milestone to celebrate with our fans and we cannot wait to share this film with them.”

Scorsese said, “The Grateful Dead were more than just a band. They were their own planet, populated by millions of devoted fans. I’m very happy that this picture is being made and proud to be involved.”

So far, no details about the film’s release date.
