Sean Murray (41) has starred alongside fellow cast members Mark Harmon (67) and David McCallum (85) in NCIS since 2003. His character Special Agent Timothy McGee is a vital member of the NCIS team and has helped solve countless cases. We were delighted to once again see him in action in the show's 16th season. 

Sean Murray became a successful actor when he was just a teenager 

NCIS star Sean Murray starred in numerous roles before appearing in NCIS. His had his first acting job, a lead role nonetheless, when he was just fourteen in the TV extravaganza Go West. 

Performances in various productions followed, in 1993 he starred in the film Hocus Pocus. This is one of his most famous performances, even though his character's dialogues were voiced by another actor! 

Murray also played one of the leading roles in the drama This Boy's Life, alongside Hollywood A-lister Leonardo DiCaprio (44). He also appeared in several cult TV shows such as ER and Palm Beach-Duo. 

We cannot imagine NCIS without Sean Murray! He is one of the few stars of the show who are members of the original cast and it is nice to know that Murray doesn't seem to be going anywhere, what with the shock of Pauley Perrette leaving the show and the constant rumours the Mark Harmon might be leaving NCIS soon!
