A familiar face on television since his early teens, actor Sean Murray later made a name for himself as a team member of a fictionalized version of the U.S. Navy's Criminal Investigations Service. Growing up in Southern California, the aspiring young actor was well positioned for early appearances in made-for-TV fare like "Backfield in Motion" (ABC, 1991) and the family feature "Hocus Pocus" (1992). The budding thespian later joined the cast of the short-lived family drama "Harts of the West" (CBS, 1993-94) and appeared opposite future Oscar winner Hilary Swank in projects like the thriller "The Sleepwalker Killing" (NBC, 1997). After a number of years jumping from one guest spot to another on such popular shows as "ER" (NBC, 1994-2009) and "JAG" (CBS, 1995-2005), Murray at last picked up a regular cast role on a hit series. As Agent Timothy McGee on the CBS drama "Navy NCIS" (2003- ), he had finally made his transition from a juvenile talent to an established adult performer.
