Higgins, Thomas Magnum’s foil, was actually named Jonathan Quayle Higgins III. He was pretty well known to constantly ramble and have arguments between the other three main characters. Ultimately though, they were still a very close unit.
John Hillerman, the actor behind Higgins, commented on his character stating that, “Higgins in any situation thinks he’s the only sane person around while everyone else is raving mad.”
T.C’s Real Name
Thomas Magnum had several sidekicks, one of them being T.C. who runs a helicopter service named “Island Hoppers.” Apparently, he was a former Marine during the Vietnam War.
He would also be the guy that Magnum would constantly persuade to fly him around on his missions, as well as get bribed to do some dirty work.
Tee Total T.C.
There was some apparent misdirection in terms of character progression since the producers suddenly made T.C. a drinker. He technically drank a beer in every episode of season 1, and suddenly just didn’t drink anymore with the following seasons.
This sudden habit change was pretty overlooked in the show but it didn’t get in the way of its success, obviously.
Gillian’s 15 Minutes Of Fame
Though there were a number of recurring characters throughout the series, the one who appeared the most was Agatha Chumley, Higgins’ friend played by Gillian Dobb. Her character was a perfect complement to Higgins as she was English and seemed to have some admiration for him.
Apparently, Gillian actually had no professional experience prior to her role on the show. She was given the opportunity of portraying Agatha for a total of five seasons.
The gun that Magnum used throughout the show was actually a Government model Colt 1911 A1 .45 cal. Pistol, contrary to popular belief. During the Vietnam War, this gun was apparently the standard issue sidearm.
Thus, it made sense that Magnum would carry such a gun from his days spent in the Navy. This gun also appeared in some of Magnum’s flashbacks of his time in Vietnam.
