One of the most discussed factors was Harmon’s reported dispute with a crew member over an incident involving his dog. According to reports, the situation caused friction on set, leading to tensions between Harmon and other cast members. Additionally, showrunners were allegedly pushing for a new creative direction, with a stronger focus on younger characters. These factors, combined with Harmon’s growing reluctance to commit to full-time filming, may have contributed to his removal from the series.
Despite his exit, NCIS has continued without him, introducing new faces while keeping the legacy of Gibbs alive. Some fans still hope for his return, but sources suggest that his departure was final. Whether it was his own decision or a move made by the producers, it’s clear that NCIS has moved forward without its most iconic star.
