With 488 episodes of NCIS to his name, it’s fair to say Sean Murray has made an impact on the franchise. But before he was gracing our screens as Timothy McGee, Sean got his start in 1991 TV movie Backfield in Motion.
Two years later, he worked alongside Bette Midler and Sarah Jessica Parker in Hocus Pocus. He’s still busy with the NCIS cast today, but eagle-eyed fans will also remember he took on a different kind of military mystery when he recurred as Danny Walden on the ’90s hit JAG.

Katrina Law
Katrina Law was a later addition to the NCIS cast, joining the team as Jessica Knight in 2021. To date, she’s appeared in 91 episodes of the hit series and worked on two episodes of spin-off NCIS: Hawai’i.
It’s not too far of a stretch for the actress who worked on 22 episodes of Hawaii Five-O. But before she was solving crimes in the sun, Katrina got her start in 2000, alongside John Travolta and Lisa Kudrow in comedy film Lucky Numbers.
