Darren Star will helm the Lifetime pilot HR starring Alicia Silverstone, the cable network announced today. The Sex and The City creator, writer and executive producer will also serve as EP on the pilot with Aaron Kaplan of Kapital Entertainment. The drama will be co-executive produced by I Melt With You writer Glenn Porter and Michael Lohmann. HR, which Lifetime says is a working title, focuses on the professional and personal changes Silverstone’s Ellen Bell, the uptight Director of Human Resources for a multinational corporation, goes through after suffering a head injury. Deadline’s Nellie Andreeva first broke the news of Silverstone joining HR back in late February. Star, who also created Beverly Hills, 90210 and Melrose Place, is repped by UTA.
