The "NCIS: LA" spinoff has assembled an impressive cast of TV drama veterans.

The March 19 episode features "Grey's Anatomy" veteran Kim Raver as NCIS Special Agent Paris Summerskill, John Corbett of “Sex and the City” fame as Roy Haines and former "ER" actor Scott Grimes as NCIS Special Agent Dave Flynn.
