Tom Selleck may be preparing for the end of "Blue Bloods" on the 2024 TV schedule, but the actor is looking back at his time on another series. Before Jay Hernandez took up the Thomas Magnum mantle, Selleck donned his legendary mustache as the private investigator in the ‘80s. Even though "Magnum P.I." is still big today, with both the original series and the reboot, Selleck has vowed to never call the series its actual name. "Magnum P.I." ran for eight seasons (162 episodes) from 1980 to 1988. Selleck looked back at his time on the series with Esquire, including when he first landed the drama. However, he admitted he hated the show’s title, and noted that he will always shorten it when he talks about it.
