ET is behind the scenes of a TV Guide Magazine photo shoot, where Chris O’Donnell and LL Cool J reveal what "NCIS" fans can expect from their highly anticipated new series "NCIS: Los Angeles."

"I think Los Angeles is going to be a great city to do the show. So many opportunities for different story lines," Chris (Special Agent G. Callen) tells ET.

"I think people, when they see it, they’ll realize that we are respectful of the original ‘NCIS’…and at the same time we bring something new and authentic, as well, to our show," says LL Cool J (Special Agent Sam Hanna).
