Brian Dietzen Brings Jimmy Palmer to NCIS: New York for October Launch

Jimmy Palmer is heading to New York.

Brian Dietzen will reprise the role of Jimmy Palmer in NCIS: New York, which will premiere on October 6, Deadline reported. The casting puts a long-serving character at the centre of the franchise's newest team.

Dietzen has been with NCIS since its first season. That run stretches back more than two decades on the original series, where Palmer became a regular presence in the lab and in the field. He has already carried the same character into other corners of the franchise, with appearances in both NCIS: New Orleans and NCIS: Hawai'i.

In New York, he joins an ensemble led by LL Cool J as Special Agent Sam Hanna. Hanna is another established name in the wider NCIS world, now anchoring a fresh unit in a new city. The set-up gives new viewers a clean entry point, with cases that start in New York rather than continuing an old storyline.

The squad around them is taking shape. Jennifer Beals plays Assistant Special Agent-In-Charge Robyn Wells, meaning the unit's second-in-command. Scott Caan plays a character called Nick. No further character details have been confirmed.

Behind the camera, Byron Balasco is the showrunner, the person who leads the writers' room and guides each episode from script to screen. A showrunner sets the tone, hires writers and directors, and keeps storylines consistent across a season. For a launch, that job includes building the working rhythm for a crew that can number in the hundreds.

For fans, this means a clear link between the old and the new. Dietzen arrives with history. Long-term viewers will recognise Palmer straight away, while newcomers meet him as part of a new team. It is a familiar face in an unfamiliar office.

The October 6 premiere date locks in when that team first appears together. More casting and story details are likely to follow before launch.
