EXCLUSIVE: While (500) Days of Summer didn’t get the Best Picture nod as some expected, good things keep happening for those involved. Zooey Deschanel has just committed to star in an HBO half-hour pilot that will be based on I’m With the Band: Confessions of a Groupie, the Pamela Des Barres’ memoir of bed-hopping with musicians and movie stars in the late 1960s. Deschanel will be executive producer with her longtime manager Sarah Jackson of Seven Summits, and Tim Gibbons, an executive producer of HBO’s Curb Your Enthusiasm. Des Barres bragged about her bedroom experiences with the likes of Mick Jagger, Led Zeppelin guitarist Jimmy Page and actor Don Johnson. But along the with excitement of rolling with famous rockers, there was also the emptiness and heartbreak of being demeaned and discarded by stars once the next pretty young thing came along. That turf was also covered by Cameron Crowe in Almost Famous. Zooey’s series is supposed to be a dramedy.
