The 10 Greatest NCIS Cameos by Famous Stars Ranked!
8. Terry O’Quinn
There was a lot of confusion that went in to choosing “Terry O’Quinn” for this role. However, Terry O’Quinn’s casting created a remarkable stint in the series. Terry O’Quinn played a recurring character on JAG during its run. As we all are familiar, NCIS is a spinoff of JAG. While appearing on JAG, Terry O’Quinn played a different character on NCIS. This was super cool that he managed to appear on both shows.
7. Lily Tomlin
In the season 9 episode “The Penelope Papers”, Lily Tomlin was cast as McGee’s grandmother, an ex-hippie who shared secrets related to caterpillars. Yes her appearance made the episode weird, but still worth remembering.
