Dark Secrets the Cast of NCIS Tried to Hide

While NCIS has been a fan-favorite crime drama for decades, its cast hasn’t been free from behind-the-scenes drama. One of the most well-known controversies involved Mark Harmon and Pauley Perrette, whose reported feud led to her shocking exit in 2018. Perrette later hinted at “multiple physical assaults” on set, fueling speculation about what really happened. Meanwhile, Michael Weatherly, who played Tony DiNozzo, faced backlash over allegations of inappropriate behavior on the set of Bull, leading to a public apology and a settlement.

Other cast members have faced personal struggles as well. David McCallum, who portrayed Dr. Donald “Ducky” Mallard, has spoken about the heartbreak of losing his son, while Sean Murray (Tim McGee) underwent a drastic weight loss that left fans concerned. From behind-the-scenes tension to personal tragedies, the NCIS cast has dealt with its fair share of secrets that many fans never knew about.
