Consistency paid off for rookie cop drama Mysteries Of Laura, which this morning became the first NBC fall series to get a full-season order with a pickup of nine additional episodes for a total of 22. Mysteries Of Laura starring Debra Messing is the only new series this season, whose ratings have stayed within .2 of its regular slot premiere and has consistently ranked as the most watched NBC program on Wednesday night. It most recently drew a 1.3 in adults 18-49 (Live+same day) and 8.3 million viewers. In the most current ratings that include Live+7 numbers, the series averages 1.9 in 18-49 and 9.3 million total viewers.

Based on a Spanish format, The Mysteries Of Laura was developed for American television by Jeff Rake who executive produces with Greg Berlanti Aaron Kaplan, McG, who directed the pilot, Sarah Schechter and Todd Lituchy for Warner Bros. TV, Berlanti Prods. and Kapital Entertainment.

While Mysteries Of Laura, which is a dramedy, has been considered a shoo-in for a back order, things are dicier for NBC’s new comedy series, especially A to Z, which is fading. Bad Judge had an alarming drop last Thursday and also is in the danger zone. Marry Me is helped by having The Voice as a lead-in but its numbers have not been very impressive given its high-profile time slot. Ditto for its companion, sophomore comedy About A Boy, which also needs a back order as it was a midseason debut last spring.

NBC earlier this fall gave orders for three additional scripts to Laura and fellow new drama Constantine ahead of its debut. The comic book-based series got off to a slow start this past Friday but it is too early to talk about its future.
