Pauley Perrette and Mark Harmon’s feud on the set of NCIS led to them being separated during filming. It began when Harmon repeatedly brought his dog to set, causing discomfort among the cast and crew, especially after the dog bit a crew member.
Perrette, a staunch animal advocate, confronted Harmon about the safety concerns. As tensions escalated, they were no longer allowed to film scenes together, with scripts deliberately written to keep them apart.
Perrette’s departure from NCIS has been rumored to be connected to this feud. Despite the challenges behind the scenes, NCIS continued to be a successful show throughout its 20 seasons.
