The cast of the long-running procedural drama NCIS is buzzing with anticipation for the return of a familiar face, and for good reason. LL Cool J, the multi-talented artist and actor, is set to make a special guest appearance in a two-part arc on the flagship series, and his colleagues on set have nothing but praise for his professionalism and impact. Describing him as an “assassin” who “just comes and gets the job done,” the NCIS stars are eager for audiences to witness his latest performance.
Brian Dietzen, who has been a staple on NCIS as the sharp and dedicated medical examiner Dr. Jimmy Palmer, shared his insights exclusively with Us Weekly at the 2026 CBS Fest. He painted a vivid picture of LL Cool J’s presence on set, highlighting his efficiency and focus. “He comes and he’s an assassin. He just comes and gets the job done,” Dietzen remarked, emphasizing the actor’s ability to deliver a powerful performance with precision. This description, while perhaps dramatic, underscores the respect and admiration LL Cool J commands from his fellow actors.
Diona Reasonover, who brings the brilliant forensic scientist Kasie Hines to life, couldn’t help but agree with Dietzen’s assessment, finding humor and truth in the “assassin” label. “Assassin! That’s so accurate!” she exclaimed on the red carpet, echoing the sentiment that LL Cool J approaches his roles with a remarkable level of skill and effectiveness. This shared enthusiasm from the cast suggests that LL Cool J’s cameo is not just another guest spot, but a significant event that will likely leave a lasting impression.
A Legacy Character Returns to the Forefront
LL Cool J’s upcoming appearance is particularly significant because he will be reprising his beloved role as Special Agent Sam Hanna. This character is not new to the NCIS universe; he first debuted on the original NCIS series in the spring of 2009, shortly before the premiere of the highly successful spin-off, NCIS: Los Angeles, which ran for 14 seasons. Hanna became a fan favorite during his extensive tenure on the West Coast, known for his intelligence, combat prowess, and unwavering loyalty.
The decision to bring Sam Hanna back to the flagship series, especially for a two-part story, signals a strategic move to connect the various threads of the expansive NCIS franchise. It allows long-time viewers to reconnect with a character they know and love, while also introducing him to a new generation of fans who may not have followed NCIS: Los Angeles as closely. Dietzen hinted at the importance of these episodes, stating that they “dare not to be missed,” suggesting a storyline with high stakes and significant character development.
The transition of a character from a spin-off back to the original series is a relatively rare occurrence in television. It often signifies a desire to explore new narrative possibilities or to tie up loose ends from a character’s past. For Sam Hanna, returning to the Washington D.C. setting of the original NCIS could offer a fresh perspective on his experiences and perhaps shed light on aspects of his career that were not fully explored during his time in Los Angeles. The “spy-like vibrato” that Dietzen mentioned could refer to Hanna’s deep cover operations and his ability to blend seamlessly into various environments, a skill that made him so compelling in his previous role.
What to Expect from LL Cool J’s Two-Part Arc
While specific plot details for LL Cool J’s two-part appearance remain under wraps, the cast’s descriptions offer clues about the nature of his involvement. The “assassin” analogy suggests that Hanna will be engaged in high-stakes operations, likely involving espionage, counter-terrorism, or a complex criminal investigation that requires his unique skill set. Given his history, it’s plausible that his return will be tied to a mission that either originates from or has implications for the broader NCIS global network.
The fact that it’s a two-part story indicates a substantial plotline that will likely unfold over two consecutive episodes. This format allows for deeper character exploration and a more intricate narrative than a single-episode guest spot. Fans can anticipate seeing Sam Hanna in action, utilizing his tactical expertise and perhaps drawing on his extensive experience to solve a challenging case. The synergy between Hanna and the current NCIS team, which includes characters like Alden Parker (Gary Cole), Timothy McGee (Sean Murray), Knight (Katrina Law), and Palmer, is something viewers will be keen to observe.
LL Cool J’s presence is also expected to bring a certain gravitas and intensity to the episodes. His established persona as a tough, no-nonsense operative, combined with his undeniable charisma, makes him a formidable addition to any storyline. The NCIS franchise has a knack for weaving in guest stars who can seamlessly integrate into the existing dynamics while bringing their own unique energy, and LL Cool J is a prime example of this.
