David James Elliott is reprising his JAG role on NCIS: Los Angeles

TVLine

The May 12 episode of the CBS drama will mark the first time that Elliott will play his JAG role of Navy Captain Harmon Rabb Jr. on an NCIS series. He'll appear in multiple episodes of NCIS: Los Angeles, a spinoff of NCIS, which is a spinoff of JAG. Elliott originally played Rabb during JAG's run from 1995 to 2005. “Bringing Harmon Rabb to work with (the Los Angeles NCIS team) makes for a formidable coalition,” says NCIS: Los Angeles showrunner R. Scott Gemmill, “and both entities are going to need all the help they can get when confronted with the greatest challenge of their careers.” Gemmill says a major goal of his to reunite Elliott with original JAG star Catherine Bell, who also hasn't appeared on any of the NCIS shows.
