ICM has brought Fran Drescher, Diane Keaton and her producing partner Bill Robinson and Emmy-winning writer-producer Elaine Pope into the fold.Drescher, the longtime star of “The Nanny,” comes aboard just as her upcoming Warner book, “Cancer Schmancer,” shapes up as a potential one-woman Broadway show, with AMG-Renaissance’s Joel Gotler and Elaine Rich Management working on that deal and Drescher in talks for a future regular TV gig. Keaton has returned to longtime agent John Burnham, who repped her at William Morris as well as Blue Relief Prods., the shingle she runs with Robinson. Keaton and Robinson were most recently involved in “Pasadena” as exec producers, with Keaton directing the show’s pilot. Pope is also a longtime Burnham client returning to the fold. She’s an Emmy-winning co-producer of “Seinfeld” and has run other shows, including “Murphy Brown,” and various TV specials with Lily Tomlin. Pope, who was signed by a team of ICM agents, is working on two pilots and two spec scripts.
