After The Firm dropped to a new series low of a 0.8 rating among adults 18-49 last night — that’s got to be a historic low for NBC– the network is pulling the drama series from the Thursday 10 PM slot effective immediately. The acquired legal drama, a sequel to the John Grisham novel and 1993 movie, will continue its 22-episode run in the Saturday 9 PM slot starting next week. Its place will be taken by NBC’s midseason drama Awake, starring Jason Isaacs. The complex, reality-defying series about a detective who finds himself leading a double life will premiere March 1. In the interim, NBC will air Grimm reruns in the Thursday 10 PM hour. Awake hails from creator/executive producer Kyle Killen and executive producer/showrunner Howard Gordon. 20th Century Fox TV is producing. It will be the third freshman drama NBC is launching in the Thursday 10 PM period this season following Prime Suspect and The Firm.
