HBO is high on getting a show with Diane Keaton on the air. Following the pay cable network’s decision not to go forward with the dark comedy pilot Tilda, which starred the Oscar winner, HBO has quietly inked a new talent holding deal with Keaton and has writers developing projects for her. The network first signed Keaton in a talent deal a few years ago. The actress became attached to a comedy project written by Marti Noxon about an old-guard feminist leader who tries to give new spark to the cause by starting a sexually frank women’s magazine. While the project ultimately didn’t go to pilot, HBO brass sparked to Cynthia Mort and Bill Condon’s script for Tilda and sent it to Keaton who signed on to do it.
