With some ratings wind at its back, NBC is keeping its foot on the gas pedal when it comes to development for next season.

A priority for the net is to seal a deal with thesp Kevin Kline and feature scribe William Monahan (“The Departed”) for a detective drama dubbed “Crowninshield,” from Scott Free Prods. and Universal TV. Project would revolve around a genius investigator-consultant and confirmed bachelor who winds up rooming with compulsive thief. Sources emphasized that the deals are not yet closed.

Meanwhile, the Peacock is getting a jump on the traditional January-April pilot season by giving an order to medical dramaAfter Hours,” from Sony Pictures TV. Back in June the network greenlit another pilot, Bruckheimer TV’s “The Secret Lives of Husbands and Wives,” which is now well along in casting and expected to begin lensing later this month or in early November.

“After Hours” was developed at the Peacock last year by TV vets Gabe Sachs and Jeff Judah. It didn’t go all the way to pilot, but NBC Entertainment chief Bob Greenblatt liked the concept and decided to give it another shot. “After Hours” revolves around a group of Army veterans who work the night shift at a San Antonio hospital. Tone is described as akin to that of “MASH,” with the doctors battling to protect their patients against the detrimental effects of health-care bureaucracy. Sachs and Judah (“Freaks and Geeks,” CW’s “90210”) are exec producing through their Sony TV-based banner.

The Peacock is continuing its push into early pilots even as the network looks to be in good shape so far, with several of this season’s frosh entries, notably comedy “Go On” and drama “Revolution.” Powered by “The Voice,” NBC this week logged wins on three consecutive nights in adults 18-49 for the first time since 2003.

The network also has a half-dozen new scripted skeins waiting in the wings for midseason debuts, including comedies “1600 Penn,” “Save Me” and “Next Caller” and dramas “Do No Harm,” “Infamous” and “Crossbones.”
