The Shocking Cancellation of the 'Tony & Ziva' Spinoff
Perhaps the biggest and freshest news for fans of the original NCIS pairing involves the highly anticipated reunion of Michael Weatherly (Tony DiNozzo) and Cote de Pablo (Ziva David). After years of fan speculation, the pair returned for the spin-off series NCIS: Tony & Ziva, which premiered to significant buzz in 2025.
However, in a move that shocked the fan community, Paramount+ announced that the series would not be renewed for a second season. The cancellation, which came despite the duo’s immense popularity and the show’s strong premise of them on the run in Europe, marks a sudden end to the latest chapter for two of the franchise's most beloved characters. This decision immediately became a major talking point among the NCIS faithful, raising questions about the future of the 'Tiva' storyline and any potential further appearances in the main series or other spin-offs.
Mark Harmon’s Unexpected Franchise Return and New Career Path
While Mark Harmon officially exited his main role as Agent Gibbs in Season 19, his connection to the NCIS universe is stronger than ever in 2025. Harmon remains an executive producer on the flagship show and is actively involved in expanding the franchise's topical authority.
The most exciting development is his confirmed return for the prequel series, NCIS: Origins. Harmon will narrate the show, which explores the early life and career of a young Leroy Jethro Gibbs in 1990s Camp Pendleton. This move ensures that the original lead character's presence and voice will guide the franchise's future, solidifying his legacy as the patriarch of the NCIS world.
Beyond television, Harmon has successfully transitioned into a new role as a published author. His non-fiction work, Ghosts of Honolulu, co-written with Leon Carroll Jr., delves into a historical spy story, proving his ability to captivate audiences with compelling narratives both on and off the screen. This new venture showcases a versatile career evolution for the former MCRT leader.
The Evolving Careers of Abby, Kate, and McGee
The other original cast members have made equally significant, yet divergent, moves in their post-NCIS careers, providing fresh updates for 2025.
Pauley Perrette's Permanent Retirement from Acting
Pauley Perrette, who played the iconic, gothic forensic scientist Abby Sciuto, has definitively closed the door on her acting career. In recent statements, Perrette confirmed her decision to retire from acting, focusing instead on her passion for social justice and film production. Her work as a documentary producer, such as with Studio One Forever, demonstrates a commitment to telling impactful, real-world stories, a stark contrast to the fictional forensic lab she inhabited for 15 years. This permanent pivot is a major piece of news for fans hoping for an Abby Sciuto cameo or return.
Sasha Alexander’s Return to the Stage
Sasha Alexander, whose character Kate Todd was tragically killed off in Season 2, has kept a steady presence in entertainment. While she is well-known for her later work in Rizzoli & Isles, her most current update involves a return to her roots in theater. In 2025, she was cast in a production of Anton Chekhov’s classic play, The Seagull, in Los Angeles. This artistic choice highlights her versatility beyond procedural dramas and appeals to a different segment of her fanbase, showcasing her commitment to diverse acting roles.
Sean Murray: The Last Man Standing
Sean Murray, who plays Timothy McGee, is the only actor from the Season 1 main cast still starring in the flagship series. Having evolved from a nervous "Probie" to the Senior Special Agent, McGee is the continuous link to the show’s original era. His confirmed return for NCIS Season 22 makes him the longest-serving cast member, a significant milestone that anchors the current iteration of the MCRT and provides essential topical authority for the long-running show.
The Enduring Legacy of David McCallum (Ducky)
The passing of David McCallum in September 2023 was a profound loss for the NCIS family. Dr. Donald "Ducky" Mallard was the intellectual heart of the team, and his character’s presence was felt deeply even after his death. The subsequent tribute episode, "The Stories We Leave Behind," in 2024, was a powerful moment that brought back Michael Weatherly’s Tony DiNozzo for a brief, emotional cameo, honoring Ducky’s memory and providing closure for the fans. McCallum's legacy extends beyond NCIS, as he was also a star of the 1960s hit The Man From U.N.C.L.E., cementing his status as a television icon whose work spans generations.
The original NCIS cast continues to shape the television landscape, whether through new spin-offs, permanent career changes, or guiding the franchise's future. Their individual journeys in 2025 prove that while the MCRT team may have changed, the stars who launched the series remain an essential part of television history.
