It looks like David E. Kelley won't be taking too much of a break after " Boston Legal" finishes its run later this season.

The prolific writer and producer is already lining up a new project. Not surprisingly for the creator of "Ally McBeal," "The Practice" and "Boston Legal," it's a drama about attorneys and their cases.

Warner Bros. TV, where Kelley signed a deal in the spring, is shopping the script to networks, and CBS and NBC are both interested, according to The Hollywood Reporter.

Kelley has had several shows on CBS in the past, most recently the short-lived "Brotherhood of Poland, N.H." in 2003. He had better success with "Picket Fences" and "Chicago Hope" in the 1990s. At NBC, he was a writer and exec producer of "L.A. Law" and produced the unscripted show "The Law Firm" in 2005.

"Boston Legal" will end its five-season run on ABC later this year. The network hasn't announced a date for the finale -- which will be the show's 100th episode -- but barring any pre-emption or hiatus, it should air sometime in December.

Details about the new show, other than the fact that it's a legal drama, are scant at the moment.
