‘NCIS: Origins’ Showrunner Reveals Mark Harmon’s Role in Michael Weatherly Reunion

NCIS: Origins, the new NCIS prequel series, has officially confirmed a major nostalgic moment for fans of the long-running procedural: Michael Weatherly’s return as Anthony “Tony” DiNozzo. For the show’s executive producer, this reunion was more than a casting decision. It was a collaboration led by franchise icon Mark Harmon.

NCIS: Origins executive producer Kyle Killen said Michael Weatherly’s return as Tony DiNozzo was made possible by NCIS’s original star, Mark Harmon. The cameo serves as a narrative bridge between the new prequel series and the established timeline of the main NCIS show, paying tribute to the original team’s legacy.

For nearly 20 years, Mark Harmon’s Leroy Jethro Gibbs and Michael Weatherly’s Tony DiNozzo were the bedrock of NCIS. Their exit marked the end of an era for the CBS hit. But with the launch of NCIS: Origins, a series that goes into Gibbs’ history before he headed up the Major Case Response Team, there was a chance to play with those character dynamics again.

“It wasn’t just a matter of working out a contract to get Weatherly to cameo,” says executive producer and showrunner Kyle Killen of NCIS: Origins. It was about respecting the relationships that already existed in the NCIS alumni community.

Killen noted that Mark Harmon, still an executive producer, remained a guiding force for the franchise even after he stepped away from acting as Gibbs. When the creative team considered adding DiNozzo, a character who surely wouldn’t cross paths with a young Gibbs in 1991, the production asked Harmon for his thoughts on how to treat the legacy characters with respect.

Harmon’s intervention was described as supportive rather than directive, but his support helped facilitate Weatherly’s participation. The collaboration shows the ongoing camaraderie among the original cast, many of whom have remained close friends since the show premiered in 2003.

Set in 1991, NCIS: Origins follows a young Leroy Jethro Gibbs (Austin Stowell) as he joins the Naval Investigative Service. But Michael Weatherly’s character, Tony DiNozzo, didn’t join the NCIS team until years later in the original show’s timeline, so his appearance needs a narrative explanation that’s not quite a regular procedural crossover.

The producers have said the cameo will be thematic rather than strictly chronological. DiNozzo’s presence is meant to tie the prequel’s story to the beloved elements of the modern NCIS era. This lets the show tip its hat to the franchise’s history while creating its own identity.

It’s Weatherly’s first major return to the NCIS universe since leaving the show in 2016. He returned for a guest spot in NCIS: New Orleans and made brief appearances in the main NCIS series in later seasons, but his involvement in Origins offers a deeper look into the franchise’s foundational lore.

“We had to maintain the spirit of the original series, but expand on its mythology,” said Kyle Killen. “Legacy characters like DiNozzo were brought in to reward fans who had been with the show for years, Killen told entertainment media.

“We wanted to be sure that we were respecting the history,” Killen said of the process. Mark Harmon’s involvement ensured decisions stayed consistent with the tone and respect shown to the characters over the show’s 20-plus-year run.

Michael Weatherly has also expressed excitement about reprising the role. Weatherly has spoken glowingly in past interviews about his time on NCIS and his relationship with Harmon, calling their on-screen partnership one of the defining relationships of his career.

CBS and Paramount are clearly trying to cash in on the goodwill toward the original cast by bringing in Mark Harmon and Michael Weatherly for NCIS: Origins. As the NCIS franchise expands with numerous spinoffs, continuity and fan loyalty are crucial.

The production’s commitment to authenticity extends to Harmon’s involvement in decisions about legacy cameos. For viewers, this reunion provides a nostalgic bridge between the gritty 90s setting of Origins and the sleek procedural format of the current NCIS series.

NCIS: Origins is scheduled to premiere during the 2024-2025 television season. Fans will learn more about the particular episode in which Weatherly appears as the airdate approaches.

Given the success of bringing back legacy cast members to other NCIS spinoffs, we may see more original cast members appear in future seasons of Origins, but no further announcements have been made at this time.
