The stars of NCIS are reaching rare air this season, and they celebrated with ET.
The CBS drama airs its 300th episode on Tuesday, which puts them in an exclusive club that includes TV classics like CSI, Law & Order and ER. The number is such a huge accomplishment that even a veteran like Mark Harmon hasn't wrapped his mind around it yet.
Still, the mile marker is bittersweet as the NCIS family will be losing one of their core members after this season. Michael Weatherly announced in January that he would be leaving the show after 13 seasons as Special Agent Tony DiNozzo. Harmon dished on how the team plans to fill that gaping hole.
"Our job here is to really move forward and to try to take the change and not so much replace as it is renew and find something new," Harmon said. "That's what we've been able to do for a while and we'll see if we can't keep doing it."
