Character mistake: Higgins' anecdote inflicted on Rick says that In Kwangju. In '49, Corky Boswick got kicked in the head during "Sunday of the Queen's birthday party", but at the time, George VI was still King, and would be until February of 1952. (00:42:25)
Character mistake: Rick reveals Magnum that a certain person committed "security fraud." That'd be securitIES fraud. (00:40:20)
The Taking of Dick McWilliams - S2-E9
Character mistake: Rick describes to his buddies the kidnapper's car as "a yellow Bronco." It's a jeep and it's orange/brown with a white roof. The description is so off that it's a miracle they found it to begin with. (00:16:10)
Wave Goodbye - S2-E7
Character mistake: At the station after the release of the first suspect, Kelly does the good cop routine and apologizes for his Sergeant, saying he does not like a private eye telling him how to do his job. Magnum 99% of the time during the show corrects people saying "private eye" with "private investigator", but here, he does not. (00:16:20)
Wave Goodbye - S2-E7
Character mistake: At the end of the episode, the cop reads the culprit his right, twists his arm and exits stage left with him. But 'left' happens to be towards the ocean, away from the patrol car. He also leaves the gun behind, lying in the sand. Worst cop ever. (00:47:45)
Character mistake: Sitting at the club's beach bar, when TC urges him to give him the rest of the money Rick says "eighty" when he is in fact giving at least the 9th 10 dollars bill. (00:16:20)
Character mistake: When Magnum looks at the pictures Higgins gave him, he sees one with a flare that will require him to ask Higgins to do some movie photography magic to remove it. However next to it there's a picture with just a slight less zoom that has no such flare. Magnum for no reason entirely ignores it while he only needed to grab a magnifying glass instead of begging Higgins and wait for the film to be developed again. (00:29:30)
Character mistake: Higgins holds his glass of brandy with Magnum's photos in the other hand and says "I don't know if you're pulling my leg, as you Yanks put it." It's really not an exclusively or typically US expression; in fact it originated in England. (00:27:35)
Character mistake: Magnum and Billy Joe Bob face one of Ito's goons. The guy is supposed to be competent with nunchakus, but he simply waves it around with no skill and in the close-up of his warrior yell, he strikes a pose with it but you can see at the bottom of the frame he misses the catch and does not grab the other stick. Obviously the extra was hired simply because of the looks and ethnicity but had never used this goon's supposed weapon of choice before. (00:24:55)
Character mistake: When Magnum parks the car in front of the Kahala Towers, the word "parks" has to be used very loosely; the car stops on the left side and at little distance from another car on the right, effectively blocking the whole road. And that is in a moment of total quiet, not rushing out of the car to save a baby or something like that. Whoever parks their car like that deserves to be shot on sight. (00:12:10)
