A new David Bowie documentary is in the works. Per Variety, director Brett Morgen — who made the Kirt Cobain: Montage Of Heck doc back in 2015 — is in the final stages of a similarly impressionistic film about Bowie. Morgen has apparently been at work on the film for four years. A source told Variety that the movie is “neither documentary nor biography, but an immersive cinematic experience built, in part, upon thousands of hours of never before seen material.” That footage seems to include at least some previously uncirculated live concert footage.
