Current Status for 2025
As of late 2024 and leading into 2025, Mark Harmon is not actively filming new episodes of NCIS. Production on Season 22 wrapped in mid-2024, and there has been no official announcement confirming his return for Season 23 or a specific 2025 filming schedule. Harmon originated the role of Leroy Jethro Gibbs in 2003 and remains a key figure in the franchise, but ongoing filming commitments for 2025 have not been confirmed by CBS or studio producers. This status reflects the intersection of long-running series cadences, actor availability, and franchise planning.
Background on Mark Harmon and NCIS
Mark Harmon’s career context
Mark Harmon first appeared as NCIS Special Agent Leroy Jethro Gibbs in 2003. Over more than two decades, the show has become one of the most enduring entries in the CBS lineup. Harmon’s portrayal of the stoic, principled team leader helped anchor the series’ tone and longevity, balancing investigative procedural elements with character-driven storytelling. His background in film and earlier television work informed a performance that has remained consistent even as the show evolved.
NCIS franchise structure
The NCIS franchise spans multiple series, including NCIS: Los Angeles and NCIS: Hawaiʻi, with interconnected storylines and recurring characters. Within this shared universe, Gibbs functions as a senior supervisory figure whose influence extends beyond his agency. The show’s format relies on ensemble casts and long-arc character development, which makes casting continuity a central consideration for producers and writers. Decisions around returning cast members typically align with broader franchise roadmaps.
Production Timelines and Planning
Network television production schedules in the United States are planned well in advance, with pilots and series orders typically decided for the upcoming season in advance of the calendar year. For long-running procedural dramas like NCIS, this means that casting and filming plans are often finalized months before public announcements. When an actor of Harmon’s stature is involved, negotiations, availability, and creative direction must align before any commitment is confirmed. As of early 2025, no official confirmation has been issued by CBS or the studio regarding renewed production that would include Harmon.

What to Watch For in 2025
Moving into 2025, the most reliable way to track potential updates about Mark Harmon returning to NCIS will be official announcements from CBS, studio leadership, or the show’s public relations team. Trade publications and trusted entertainment outlets may report on casting developments when negotiations reach later stages. Fans can monitor official channels rather than unverified reporting to separate confirmed plans from speculation. Absent an official statement, it remains an open question whether Harmon will reprise his role this season.
Comparing Rumors Versus Verified Information
Social and entertainment media often amplify rumors about returning cast members, especially for long-running shows like NCIS. These reports may cite unnamed sources or interpret routine production activity as confirmation of specific cast returns. In contrast, verified information comes from official press releases, network programming announcements, and transparent studio communications. Until an official statement is issued, treating online speculation as unconfirmed is the most reliable approach.
- Rumor-based claims rely on unnamed sources and lack corroboration.
- Verified statements come from official network or studio communications.
- Timing matters: announcements typically align with upfronts and production calendars.
