NCIS characters have a lot of explaining to do. Week after week, they must delve into all kinds of military crime. Who would have thought there’d be this much sleuthing to do, and that audiences would love it so much. With a show that consistently turns in top ratings, you can be sure that the NCIS guest stars roster is going to be impressive. With legends, veteran character actors, and stars on the rise, the NCIS TV show guests include some impressive names.  
 
From a pre-Little Miss Sunshine Abigail Breslin acting her guts out as a young kidnap victim helping the NCIS team catch her captor, to a young and unknown Zac Efron trying to explain himself, many future stars got their starts on the popular CBS military crime drama series.  
 
But it's not just the up and coming in the hot seat. Titans from the stage and screen have had to face the NCIS squad. Beloved actor Charles Durning gets caught up in murder; Hal Holbrook tries and fails to get away with murder; Gena Rowlands, Lily Tomlin, and Colin Hanks can all claim their spot as NCIS characters, getting caught up in the intrigue. From Bob Newhart to Dean Norris, you never know who’s going to pop up with NCIS cameos and get grilled by Gibbs.
