Robin Masters, whose face is never seen in this series, was voiced by Orson Welles. The producers eventually wanted Welles to appear as Robin Masters's face, but he died in the sixth season before the series ended. In the seventh season, Magnum began developing the theory that Higgins was Masters. In the final episode, the real Robin Masters finally appeared.

The colorful helicopter T. C. used for his Island Hopper charter service was a Hughes 500, a commercial variant of the Hughes OH-6 Cayuse developed for the US military.

Roger E. Mosley was a licensed private helicopter pilot, but he was not allowed to perform the flying. The pilot crew would take the other seat and hide behind him with a second set of controls for close-ups, then cut, land and the actors would get out so the pilot could perform the flight or the stunt. The pilot would also wear a muscular body suit to resemble T. C., if necessary.

He also plays a casual game of basketball.

Jonathan Quayle Higgins III has several illegitimate brothers who share his father, General Albert Stanley Higgins, but have different mothers. Father Paddy McGuinness is an Irish priest. Elmo Ziller is a Texas rodeo owner. Don Luis Mongueo is the royal heir to the throne of Costa De Rosa in South America. There are also Soo Ling (Chinese), Elizabeth Whitefeather (Native American) and Catoomba Noomba (African). Only Elmo, Paddy and Don Luis were actually seen; each was played by John Hillerman in dual roles and each was portrayed as an extreme contrast to Higgins's characterization.

Higgins was a British prisoner of war. He helped build the bridge at the time. The model bridge was broken several times over the course of the series.

When Magnum's misfortunes brought trouble to the Robin Masters Estate, Higgins armed himself with a British Webley Mk-VI.455-caliber revolver. It was a standard British military weapon in both World Wars, so it is reasonable to assume it was Higgins's personal weapon from his time serving in the British Army during World War II.

Along with his signature Detroit Tigers cap, Magnum also wore a U.S. Navy cover.

Thomas Magnum's weapon of choice was a Government model Colt 1911 A1.45 caliber semi-automatic pistol. When needed, he usually carried it tucked into his waistband, a practice also known as "Mexican carry." The Colt 1911 A1 was the standard U.S. military pistol during the Vietnam War, so it is reasonable to assume it was his personal weapon from his Navy days.
