The 51-year-old Corbett -- also known for portraying Sarah Jessica Parker's boyfriend on Sex and the City -- explains the role of his character, Roy Quaid. "Roy was an agent, but he was wounded so he's semi-retired and Red Team needed an analyst so they brought him in." The star said he was "appropriately nervous" the first time on the set of NCIS, which he said he initially took an interest in because he always been a fan of longtime franchise star Mark Harmon.

Corbett is also a country music artist and explained that he recently got the call about being cast in the spinoff while celebrating in a bar after receiving good reviews of his latest album, Leaving Nothin' Behind. "Where have you been? I need you to get to LA tomorrow to meet the people at NCIS: LA," he recalls his agent saying. "I said, 'It is not happening tomorrow... I live on a ranch and I have animals and I need advance notice, it's a big process.'"
