HBO is divorcing itself from Marriage, Steven Bochco's much-talked-about upcoming drama series set almost entirely in the bedroom of one couple's New York City apartment. After viewing the pilot, the network "had serious reservations about whether it could be sustained as a series," an HBO rep tells Variety. Bochco, meanwhile, is developing a new cop drama for ABC — a possible successor to NYPD Blue, which is entering its 11th (and possibly final) season this fall.
