Screenwriter Topper Lilien, whose last big-screen writing credit was 2000's live-action Dungeons & Dragons, will pen the script.

Since the film will take place prior to Garcia's Dead days, Greenfield said it's unlikely the film will feature the band's music, opting instead for a soundtrack filled with "bluegrass, folk ballads and jugband music" that was influential at the time. Bob Weir and songwriter Robert Hunter will be portrayed in the film.

The Jerry Garcia biopic that's currently in the works has hit a major roadblock, as Grateful Dead productions is blocking any use of the Dead's or Garcia's music for the film. They've also stated that director/producer Amir Bar-Lev will not be granted access to any of Garcia's family members.

"We want to make clear that neither Grateful Dead Productions nor the Jerry Garcia Family LLC are in any way working with -- or are in any other way affiliated with -- the supposed upcoming Amir Bar-Lev-directed biopic about Jerry Garcia," Grateful Dead Productions said in a released statement. "Furthermore, we will not be licensing any recordings from Grateful Dead or Jerry Garcia's music library for this production nor will we provide the producer/director with access to any Garcia family members."

That might also be because there's been talk in the past about turning "Living With the Dead" into a film. If that's still out there somewhere, they might have an exclusive deal. Who knows, maybe the surviving Dead want full control over a project.
