Heads are rolling over at Crane Poole & Schmidt.

Julie Bowen, Mark Valley, Rene Auberjonois and Constance Zimmer have all been let go from the show, sources tell me. A rep for David E. Kelley Productions confirms that their contract options were not picked up.

To fill the void, Night Court's John Larroquette is joining the show as a series regular next season, but he won't be reprising his Emmy-winning role from Kelley's The Practice. Instead, he will be playing an attorney from the New York offices of CP&S. Also Dirt's Tara Summers will be coming on board as a young associate. Finally, current cast member Christian Clemenson (Jerry) has been upped to series regular.

Phew, that's a whole lot of change for one TV show. Thoughts on the big revamp, Legal fans?
