There’s been a flurry of online chatter lately suggesting that NCIS legend Mark Harmon was permanently removed from the show in response to the Tom Selleck–Blue Bloods drama, but let’s clear the air: there’s no credible connection between the two events. Harmon, who played Special Agent Leroy Jethro Gibbs for nearly two decades, stepped away from NCIS in Season 19, a decision that was planned and mutually agreed upon behind the scenes.
The idea that his departure was retaliation for network politics involving Selleck and Wahlberg is pure internet speculation—fueled more by dramatic comment threads and conspiracy-loving fans than any real evidence. Some users on social media and gossip sites have been connecting dots where there may be none, creating a narrative of “Hollywood betrayal” that pits veteran stars against one another in a ratings-fueled soap opera.
In reality, both actors are beloved for their iconic roles and have had long, successful careers. Harmon’s reduced role on NCIS and Selleck’s rumored frustration over a Blue Bloods spinoff highlight the changing landscape of TV, where networks chase younger audiences and evolving storylines. But as for a secret vendetta? That’s more fiction than anything either of these guys would ever put on screen.
