NCIS: Los Angeles

LL Cool J tries to perform his own stunts, where possible. He explained: "I want people to know that I'm invested in the character and I want to give them the real experience".

Paul Walker was considered the role of G. Callen.

Chris O'Donnell has expressed interest in having Michael Weatherly appear on the show. This finally occurred in seventh season, although the characters did not acknowledge that they knew each other.
