NCIS Season 17: Christopher Lloyd plays "Joe Smith"

According to TVLine, Lloyd will play 95-year-old Navy veteran "Joe Smith" who served on the USS Arizona when it was attacked in 1941 at Pearl Harbor. "Smith" is determined to have his ashes laid to rest with his fellow sailors once he passes away.

The report describes the character as  "sharp, spry, and an unapologetic curmudgeon,"  and he will apparently become the focus of an investigation led by "Gibbs" (Mark Harmon).

Christopher Lloyd has won two Emmy Awards for his work as "Rev. Jim Ignatowski" in Taxi and another one for his role in Disney's Road to Avonlea.

More updates on NCIS coming soon. The next episode ("In a Nutshell") will air on March 10 at 8pm (7 central) on CBS!
