Mark Harmon and Michael Weatherly to Reunite on ‘NCIS: Origins’ for First Time in 10 Years

Mark Harmon and Michael Weatherly are set to appear together again on the CBS and Paramount+ series “NCIS: Origins,” marking their first on‑screen reunion in a decade. The casting announcement confirms that both actors will be part of the new installment of the long‑running franchise.

The two performers previously shared screen time on the original “NCIS” series before their respective departures, and the upcoming collaboration will be the first occasion they have worked together since that time, roughly ten years ago. Their return to a shared project has been highlighted as a notable development for fans of the franchise.

“NCIS: Origins” joins the broader “NCIS” franchise, which continues to expand across broadcast and streaming platforms. The series will be available on CBS as part of the network’s Tuesday night lineup and will also stream on Paramount+ for subscribers.

The franchise’s recent performance has been strong, with CBS reporting a 39 percent increase in audience size for its Tuesday premiere night, reflecting heightened viewer interest across its various “NCIS” titles. The boost has been attributed in part to the franchise’s continued programming slate and the anticipation surrounding new entries such as “NCIS: Origins.”

The reunion of Harmon and Weatherly is being positioned as a key element of the new series, offering a point of connection for long‑time viewers while the franchise maintains its upward audience trajectory.
