Since early 2015, fans have been eagerly anticipating a Grateful Dead documentary with Martin Scorsese attached as producer. While hopes to release the documentary in 2015 – the band’s 50th anniversary – fell short, recent talks and rumors seem to indicate that the team is making progress on the film. Now, a new report in Showbiz411 suggests a change of format for the Grateful feature.

According to the report, the film has grown so much that it will become a four-hour mini series, and may even debut at the Toronto Film Festival. Still untitled, the film directed by Amir Bar Lev continues to expand with hours of archival footage and interviews with band members, family members, and more.

The report also indicates that outsiders, like members of Dave Matthews Band, Phish or Bob Dylan (so named in the report), won’t be featured in the four-hour film. It’s all Grateful Dead, all the time. With Scorsese still on board, as well as Eric Eisner, Nicholas Koskoff and Justin Kreutzmann, there is definitely hope that this will happen after all.

Furthermore, Bob Weir was recently reported to be working with Amazon on a biographical docu-series. Could this be the same project? Only time will tell.
