To help the portrayal even further, Murray said the younger actor was sent tapes of the NCIS agent in action so that he could get all the character’s mannerisms down pat.
Sean Murray wasn’t a part of the casting, but he was impressed with how similar actor Charles Tyler Kinder looked as a teenaged McGee.
As Tim heads back to high school, NCIS will also go back to the past with scenes featuring a young McGee.
