Velvet Goldmine director Todd Haynes is currently working on a docuseries about the Velvet Underground, Variety reports.Haynes told Variety about the episodic documentary Monday, saying that the project and will be "challenging" because there isn't exactly a Grateful Dead–style vault somewhere of unreleased Velvets film and audio to sift through. He reportedly says he's excited for "the thrill of the research and visual assemblage."Haynes has built a career on narrative films about musical figures, from 2007's ensemble Bob Dylan biopic I'm Not There to the fictionalized Bowie-and-Bolan surrogate in Velvet Goldmine to that movie he made about Karen Carpenter using Barbie dolls. But this will be his first real foray into documentary film.According to Haynes, the series will "rely certainly on Warhol films but also a rich culture of experimental films—a vernacular we have lost." It'll also feature interviews from the surviving members of the Velvets and people in their scene, so get ready for some old heads rehashing 60s NYC like it's the prologue to Please Kill Me.The as-yet-untitled Velvet Underground documentary series is currently in development, and there's no official word yet on when the whole thing will be released. If you're in need of some Velvets content in the meantime, there's a Nico biopic about the singer's later years coming to the Venice International Film Festival in August, Pitchfork says. Or just go watch A Symphony of Sound, the 1966 verité doc that Warhol and Paul Morrissey shot of the Velvets playing through a rehearsal—the whole thing is up on YouTube right now.
