The Best NCIS Guest Stars Ever

The ratings juggernaut that is NCIS has been on the air for an impressive 17 seasons now. Ever since 2003, Special Agent Leroy Jethro Gibbs (Mark Harmon) has been leading a team of highly skilled investigators who solve violent crimes involving Naval and Marine officers. 

Though many major characters have come and gone over the years --  including DiNozzo (Michael Weatherly), Ziva David (Cote de Pablo), and Quinn (Jennifer Espisito) -- the main cast has remained largely the same. Fan favorites like Sloane (Maria Bello), Ducky (David McCallum) and, of course, that irresistible Torres (Wilmer Valderamma) continue to draw in millions of viewers every week to see how they'll save the day. 

However, there's another segment of important NCIS characters who have been an integral part of the show: the guest stars. Many, many actors who are now big A-list stars -- and some who were already huge stars -- have come to play on NCIS; from Sterling K. Brown to Misha Collins to Jamie Lee Curtis, well-known guest stars continue to be part of the show's appeal and legacy. Here are 46 huge stars who appeared on NCIS over the years. Do you remember all their cameos?
