"NCIS" hits 200th episode mark

(CBS) "NCIS" is hitting the 200-episode mark on Tuesday night, with an episode that asks, "What if?"

In "Life Before His Eyes," Gibbs (Mark Harmon) goes for a morning coffee and ends up in a confrontation with a gunman, leading him to ponder choices he made in the past and present. 

The flashbacks and alternate scenarios mean some familiar faces will be seen in the episode, including Muse Watson as Mike Franks; Ralph Waite as Jackson Gibbs; Joe Spano as Senior FBI Agent T.C. Fornell; Darby Stanchfield as Shannon Gibbs; and Rudolf Martin as Ari Haswari.

"We're doing some really cool things, not only with people we were able to get back,but also with visual effects," showrunner Gary Glasberg told TVLine. "It's the kind of episode I hope people save to their DVR, because they're going to want to watch it multiple times. A barrage of faces and images come at you, and very quickly."

He added, "For a diehard fan, [Episode 200] will be a lot of fun. We definitely thought it through!"

The 200th episode airs at 8 p.m. ET on CBS. You can watch "NCIS" star Michael Weatherly's interview on "CBS This Morning" below.
