Returning NCIS Star Promises Fans Will Be ‘Surprised’ By NCIS: ORIGINS Crossover

Mark Harmon says fans will be “surprised” by his upcoming appearance in the upcoming NCIS and NCIS: ORIGINS crossover.

“My first reaction to it was ‘How are they going to do it?’” Harmon, who played Leroy Jethro Gibbs on NCIS for 19 seasons, told CBS. “But they have an idea that I thought made a lot of sense, and I’m here to support the show the best way I can, and part of that is being asked to do something as an actor that I find both pertinent to the storytelling and also believable.”

Harmon said he was “glad to be part of it, and I hope people like it,” adding, “I think [fans] are going to find out [what Gibbs has been up to]. I think they’re going to be surprised a little bit, too.”

“I’m just here to support, and that has to do also with supporting this cast and this show and this network, and kind of being proud of something you put your name on,” the actor concluded.

Gibbs spoke about the crossover more in an interview with TV Insider, saying showrunners David J. North and Gina Lucita Monreal are “really talented” and he “trust[s] them.”

“This is a process, and it’s been pretty interesting to watch this develop and also have a memory of what it was like 20 years ago when the mothership was started,” Harmon shared. “So for me, other than doing the voiceover [in NCIS: ORIGINS], I just trust these two showrunners and what their ideas are. That’s my job to support that. And this is part of their thought of what is right for the show. So that’s why I’m part of it.”

So, does this appearance mean Harmon’s version of Gibbs might be coming back again for future episodes?
