How a modern reboot turned a classic detective show into a shared television universe
In short: The 2018 reimagining of Magnum P.I. did more than just update a 1980s icon. By integrating its narrative with other crime reboots, the series established a sprawling, interconnected world. While the show faced production shifts and a network move, it redefined its classic characters for a new generation.
Developed by Peter M. Lenkov and Eric Guggenheim, the 2018 Magnum P.I. reboot brought Thomas Magnum, a former Navy SEAL, to modern Hawaii. The series maintained the core premise of the original 1980s show: Magnum resides in the guest house of Robin Masters’ estate, Robin’s Nest, while working as a private investigator. In this version, however, the character of Juliet Higgins—the estate’s majordomo—was genderswapped from the original Jonathan Higgins to allow the show to carve out its own identity. Alongside Magnum, Higgins eventually becomes his investigative partner, supported by friends Rick Wright and T.C. Calvin, while navigating complex dynamics with Honolulu Police Department detective Gordon Katsumoto.
The series was part of the so-called Lenkov-verse, a shared fictional universe encompassing other reboots like Hawaii Five-0 and MacGyver. This connectivity allowed for frequent crossovers, with characters from Hawaii Five-0 appearing throughout the show’s run. Despite being a Top 25 show in viewership, the series faced turbulence. In 2020, Lenkov was fired following allegations of a toxic work environment, leading to a shift in leadership. The show was canceled by CBS in 2022 after four seasons due to contract disputes, only to be rescued by NBC for a final two-part fifth season.
The production history reflects the complexities of modern television. After its initial CBS run, the show moved to NBC, with the final season concluding on January 3, 2024. Throughout its tenure, the series balanced procedural crime-solving with character-driven arcs, such as the evolving tension between Magnum and Higgins. By blending the legacy of the original 1980s series with a modern, interconnected framework, the reboot attempted to honor its predecessor while establishing a distinct, contemporary footprint in the action-drama genre.
