NBC is solidifying its support for well-received but struggling new drama Prime Suspect with a six-script order. It follows similar script pickup for sophomore dramedy Harry’s Law yesterday. Prime Suspect is NBC’s only new fall scripted series whose fate has not been determined. The network recently gave comedies Up All Night and Whitney full-season orders and canceled drama The Playboy Club and comedy Free Agents. Such a script order allows producers to keep a series in continuous production if the network gives it an episodic back order. After a slow start, Prime Suspect held steady last Thursday (1.5/4), when virtually all other shows were down. The cop drama starring Maria Bello is getting additional sampling on Monday where its repeats replaced Playboy this week.
