See How the 'NCIS: LA' Cast Has Changed Since Their First Seasons (PHOTOS)

The cast of NCIS: Los Angeles has changed a bit from its first season (and its introduction over on NCIS).

Characters have come and gone (RIP Dom), one of the agents has gotten to know quite a bit about his past (including his name), and, 10 years later, partners have even gotten married. But, for the most part, the team is the same.

Chris O'Donnell (Callen), LL Cool J (Sam), Daniela Ruah (Kensi), Linda Hunt (Hetty), Barrett Foa (Eric), and Eric Christian Olsen (Deeks) all appeared in Season 1 (though Olsen only guest starred in two episodes). Renée Felice Smith (Nell) joined in Season 2. And they're still on the show going into Season 11.
