Now
Just in today: ET has learned that CBS is planning a new show that will be launched by the popular "NCIS" series.
Nina Tassler, President, CBS Entertainment gives the details: "It is happening. We are doing it. We have seen an outline and we are in great shape. 'NCIS' was an episode of 'JAG.' The new show will be an episode of NCIS."
cast:The ensemble for CBS' planned NCIS spinoff continues to flesh out. Not long after it was reported that Chris O'Donnell and LL Cool J are circling two lead roles, three other characters have been cast.
Louise Lombard, who played CSI's Sofia Curtis for three seasons, has landed what is considered the series' female lead: Clara, a former major in the military police turned investigator.
The Hollywood Reporter also reports that Peter Cambor (Notes from the Underbelly) will play Nate, a quick-witted operational psychologist.
Lastly, Daniela Ruah (a newcomer to American television) has been cast as Kensi, a young investigator specializing in forensics and criminology.
Should O'Donnell and LL sign on the dotted line, they will fill the roles of Callen, a "human chameleon," and Sam, a former U.S. Navy Seal, respectively.
Just as NCIS was born of a JAG episode, this latest offshoot will kick off as an episode of NCIS.
