So far, the NCIS Season 22 is still in the middle of its process, thanks to the seven confirmed leads and, yes, the basic question still lingers: who is in NCIS Season 22? The answer: the very same cops and investigators who are doing the heavy lifting in the show’s plot; it’s Sean Murray, Wilmer Valderrama, Katrina Law, Brian Dietzen, Diona Reasonover, Rocky Carroll, and Gary Cole who comprise the season's confirmed principal cast.

The season's confirmed principal cast is still a major contributor to the show’s success despite the production and airing status of NCIS Season 22 being unclear. The season first aired on October 14, 2024 (after a delayed fall start), included confirmed guest and recurring characters (notably LL Cool J as Sam Hanna and Laura San Giacomo as Dr. Grace Confalone), and again, because of production interruptions and scheduling conflicts earlier in 2025, had a rough planning of 20 episodes while not yet airing all episodes fully.

Seven main actors who are regulars in the NCIS Season 22 cast have been signed officially and are the mainstay of the season:

  1. Sean Murray - Senior Special Agent Timothy McGee
  2. Wilmer Valderrama - Special Agent Nick Torres
  3. Jessica Knight, Special Agent Katrina Law
  4. Chief Medical Examiner Dr. Jimmy Palmer, Brian Dietzen
  5. Diona Reasonover, a forensic expert, Hines, Kasie
  6. Leon Vance, director of NCIS, Rocky Carroll
  7. Supervisory Special Agent Alden Parker, who leads the Major Case Response Team, is Gary Cole

These seven actors are confirmed to be the main cast of NCIS Season 22, appearing in and being billed alongside the season's previously released episodes. The continuing structure for NCIS’s procedural work revolving around these characters, the roles of the field agents, medical examiner, forensic analysis, and leadership, together constitute the operational core of NCIS Season 22.


NCIS Season 22 confirmed recurring and guest appearances

Besides the main cast, the characters returning in NCIS season 22 were already confirmed. Laura San Giacomo, who played team psychologist, Dr Grace Confalone, is said to be regular, but only and the episodes that call for her advice.

Sam Hanna, portrayed by LL Cool J, was confirmed to make an appearance as a guest in one of the episodes on April 21, 2025 ( episode 18, “ After the storm”). There is no question in the fact that he would be making the switch. The episode will be formally featured in his return. These appearances are confirmed, but the network has not revealed any additional guest members.

The reports and episode recaps confirm these particular appearances, but the network has not mentioned any other recurring or guest cast members.


Premiere, production delays, and episode status

The strikes of 2023 had a lasting impact on the industry. This was one of the main reasons for the new schedule. This resulted in the late premiere of NCIS Season 22, which was on October 14, 2024. It is considered a late fall start among other seasons.

Among the operational delays were the local wildfires that the production team had to respond to, and this led to the temporary halt in production in early 2025. Due to this reason, the schedule was thrown off, which in turn affected the number of episodes that were aired.

These reasons of disruption changed the normal pattern of the show and hence created the mid-season breaks.

Episode count and airing status: The year has not ended yet, but because of production halts and rescheduling, only part of the season's 20 planned episodes had aired by the end of November. However, if you go by the episode table and the official network episode pages, which are the most reliable, then the season is no doubt going to be around 20 episodes long.

Some of them were aired in late 2024 and early 2025, while others are either scheduled for airing or are still waiting to be assigned an air date.


What the cast and production picture means for viewers

Continuity of characters: For those invested in the character arcs, Season 22 promises continuity-the seven main cast members form the backbone that has kept the show running concerning investigative rhythm and character development. Their presence has, till now, been appreciated along with all the episodes that have aired.

Selective recurring/Guest appearances: The confirmed return of Dr. Grace Confalone and the crossover of Sam Hanna are the most significant non-main cast highlights of the season so far. These are limited appearances that serve very specific storyline purposes.

The network chose to have a new earring format for season 22 due to the delays that occurred earlier. Hence, the viewers of the show are advised to check for the latest air dates only through official episode pages or the network's main website.


The storyline of Season 22 is still developing, and the confirmed main cast is leading the way. The season was affected by some delays; consequently, both production and the release schedule were changed. The number of episodes planned is around 20, although not all of them have already been released.

The coming and going of characters such as Sam Hanna and Dr. Grace Confalone are giving the franchise continuity. During the season's march, more updates can be anticipated as CBS wraps up the schedule for the remaining episodes.
