Jack Lord starred as Steve McGarrett, head of the elite state law enforcement office which worked alongside the chief of the Honolulu Police Department. James MacArthur starred as Danny Williams, McGarrett's right-hand man. McGarrett and "Danno" were straight-laced men with extreme dedication to law and justice fighting the forces of evil around the islands, especially in seedy downtown dives. Kam Fong Chun (who played Det. Chin Ho Kelly) was, in real life, a former HPD officer during World War Two. In several episodes of the show's first season, McGarrett mentions "Chief Dan" helping the Five-O unit with things like extra manpower or investigative resources; this referred to the real life Honolulu Police Chief Dan Liu (1908-1986), HPD's longest serving chief (1948-1969). (Chief Dan Liu also appeared as himself in the 1952 film Big Jim McLain.) A modern-day remake of the series aired on the same television network from September 2010 to April 2020. Like its predecessor, the remake prominently featured the HPD, usually uniform officers assisting the Five-0 task force in apprehending suspects, collecting evidence and securing crime scenes. The main characters, as of season 6, were all either former HPD officers or have some connection to the HPD: Steve McGarrett's father John was a former HPD sergeant, Chin Ho Kelly was John McGarrett's protege and reached the rank of Lieutenant, Danny Williams transferred to HPD from Newark PD in New Jersey, Kono Kalakaua was a fresh graduate from the HPD Academy and Lou Grover was the commander of the HPD SWAT Team. Kam Fong Chun's son Dennis Chun had a recurring role as HPD Sgt. Duke Lukela. Magnum, P.I. From December 1980 to September 1988, Magnum, P.I. aired on the same network as Hawaii Five-O (in fact, some of the shooting was done on the same sound stage). Starring Tom Selleck as former U.S. Naval Intelligence and SEAL officer (and Detroit native) Thomas Magnum, Magnum, P.I. is about a private investigator working closely with Honolulu Police Department officers Nolan Page and Yoshi Tanaka, while trying to enjoy the "easy life" at the estate of a very reclusive mystery writer named "Robin Masters" and his "butler" Jonathan Higgins (played by Texas-born veteran actor John Hillerman). The series was widely applauded for being the first to recognize the difficulty Vietnam War veterans faced in making the readjustment to civilian life. Many episodes touched upon the impact that serving in Vietnam had
