TNT, which has ordered three pilots in recent weeks, is closing in on greenlighting two more projects.

One of them, in fact, has already received the go-ahead: "Bunker Hill" will star Donnie Wahlberg as a Bostonian who returns from covert government duty abroad and goes to work as a police officer on the streets of his old Bunker Hill neighborhood.

Wahlberg ("The Kill Point," "Boomtown") will also serve as an exec producer, according to The Hollywood Reporter, along with writer Walon Green ("Law & Order") and Jon Avnet ("The Starter Wife," "88 Minutes"), who will direct the pilot. Avnet and Wahlberg previously worked together on NBC's "Boomtown" and the feature "Righteous Kill."

The cable network is also close to ordering a pilot from superproducer Jerry Bruckheimer about detectives in Los Angeles and the temptations they face when they work undercover. Bruckheimer will exec produce with writer Doug Jung ("Big Love") and Danny Cannon, an executive producer and frequent director on Bruckhemier's "CSI" franchise on whose idea the show is based.

The two pilots join the Ray Romano dramedy "Men of a Certain Age," medical drama "Time Heals" and the crime/family saga "Night and Day" in TNT's development hopper, in addition to two more shows, "Leverage" and "Trust Me," launching in the next few months. All are part of the network's goal to offer three full nights of original programming by 2010.
