CBS and Tribeca Prods. are teaming to develop three pilots that will be executive produced by Tribeca partners Robert De Niro and Jane Rosenthal.

According to Variety, the deal gives Tribeca a guarantee that one of the three projects will be produced as a series pilot.

The first project is an hourlong pilot that will be written by William Monahan, the Oscar-winning writer of The Departed who will make his first foray into TV with an untitled drama set in New York.

Monahan, who recently scripted Body of Lies and Edge of Darkness, is writing the pilot targeted for the network's fall 2009 schedule. Rosenthal wouldn't reveal the subject matter.
