Albert Berger, Ron Yerxa and Eric Eisner have signed on to produce a biopic about Grateful Dead frontman Jerry Garcia that will offer a revealing look at the roots of the counterculture icon, according to The Hollywood Reporter.

The untitled project will focus primarily on Garcia's early life in the Bay Area before he joined the band that would become the Grateful Dead -- a period that includes a stint in the military, a life-changing car accident and his first creative encounters with members of the Northern California music scene including future Dead bassist Phil Lesh.

Producers have acquired rights to Robert Greenfield's book "Dark Star," an oral history of Garcia from dozens of people who knew him, including musicians, relatives and artist friends like Ken Kesey. Music rights also are being negotiated, though given that the period in Garcia's life that's covered is pre-Dead, producers could avoid some of the trickier negotiations.

Topper Lilien, who penned Universal's Paul Newman-starring drama "Where the Money Is," has been attached to write the screenplay.

No production date has been set.
