Magnum, P.I.

A Sense of Debt - S4-E8

Other mistake: Fun gag but does not make sense; Magnum has a prolonged conversation at the bar (not a random brief chance encounter) with Lou Whitaker and Alan Trammel, and he, a huge Tigers Fan who in other episodes proved to be able to recognize obscure players from other past teams, needs the bartender to tell him who they were.

Don't Say Goodbye - S1-E15

Other mistake: Twice in the episode it is explicitly said that Magnum's phone has been disconnected, and that Higgins checked with the phone company. Yet at the end, it turns out 'the lads' chewed on the cable. Surely the phone company wouldn't tell the estate manager that the line has been disconnected for billing problems (so, a well determined administrative issue with proper paperwork done) when it's a wiring problem.

Show generally

Other mistake: Throughout the entire run of the series, the very first shot of the opening contains a mistake; the helicopter's tail rotor is on the right side (mirrored), going then to its actual position (left side) for the rest of the sequence.

Letter to a Duchess - S4-E6

Other mistake: Magnum and Vivian are not listening to the TV at loud volume (they have a quiet time watching and talking without raising their voice), but Higgins, all of a sudden hears it all the way from the main house and is greatly bothered by it.

Smaller Than Life - S4-E3

Other mistake: Lee has an Atari 830 Acoustic Modem, which has on its front panel an instructional "cord side" illustration, showing the proper direction for the phone cord when the phone handset is secured in the top two cups. The telephone's cord must be placed at the right side in order for the acoustic coupler to work, but in both Lee's and Magnum's closeups, the phone cord is on the left side, but the acoustic coupler works properly. This is impossible. Also noticeable in closeups is the covered brand name of Atari on Lee's devices. (00:24:20 - 00:27:20)

Season 1 generally

Other mistake: With episode 11, "Thicker Than Blood", the opening changes to the truly iconic version associated with the series, with a large overhaul of footage. There must have been some hiccup making it though, because the title of the series appears as "Magnum PI", no punctuation. There's a version of the opening that includes the correct "P.I." title card.

Operation: Silent Night - S4-E10

Other mistake: The three friends mistake Higgins' footprints in the sand for a pirate's. They find him and they have their explanation; Higgins is carrying a cane and some palm leaves; dragging the palm leaves, he involuntarily erases the prints of his foot, while the cane leaves a circular print akin a wooden leg's. That makes no sense, because as it is shown, Higgins is holding the cane in his right hand, and dragging the palms with his left; he'd wipe the prints of his left foot, if anything. And yet when Rick pointed at the prints, it was obviously a left footprint. (00:18:20)

Limited Engagement - S4-E5

Other mistake: Magnum rewinds the answering machine tape hitting the opportune button just once, and it plays on its own the exact bit he needs to listen to, without any intervention on his part. (00:36:20)

Limited Engagement - S4-E5

Other mistake: The opening sequence featuring a blonde in an orange bikini showering on the beach is recognizable as reused from a kidnapping scene in one of the early episodes of the series, 4 years before; China Doll. (00:01:50)

Distant Relative - S4-E4

Other mistake: Rick enters Wendy's room shouting like a madman, and then reaches the bedroom door trying to turn and pull the knob. He bangs the door, calls for Magnum's help, and both then bust the door open. In all that, the guy going through Wendy's underwear and bed sheets is still unfazed and stops what he's doing merely when they almost fall on him. (00:18:00)

Distant Relative - S4-E4

Other mistake: Magnum wakes up because Agatha and Higgins are playing with their model planes that loudly buzz in the air. He opens his bedroom window and here they are, by the guesthouse, with a direct view and Higgins waving at him. He then gets out to give them a verbal beating, and he's coming from the main house area. (00:02:15)

Smaller Than Life - S4-E3

Other mistake: When Magnum makes a typo with the "Torpo Corporation" name, he types "Torbo"; B and P are nowhere near. And to fix it he types a B, and backspaces. That's not how it worked, ever. (00:27:40)

Smaller Than Life - S4-E3

Other mistake: Higgins is outraged about a precious 1923 sketch being stolen by Rick's friend. Then again, that invaluable (as he puts it) piece of paper was stored in an open rack, rolled up with a rubber band. That's hardly how such an antiquity would be preserved by someone who finds it this valuable.

Smaller Than Life - S4-E3

Other mistake: The guy rummaging through Waldo's stuff in the room does not get alerted by their loud chat outside the room, nor the door unlocking, not even their steps; he just turns around suddenly when they both are in the room, standing still in silence and looking at him, who has his back turned to them. Must have had eyes on the back of his head. (00:09:10)

Luther Gillis: File #521 - S4-E2

Other mistake: Luther decks one of the old ladies with a punch. When he strolls past them after slipping Magnum a mickey, he looks back at them, and one in particular, who is sporting a patch. It is not the same lady he punched earlier. (00:17:35 - 00:21:30)

Luther Gillis: File #521 - S4-E2

Other mistake: The guesthouse scene with Magnum and Luther opens with a prolonged gag about Magnum "finally" getting an answering machine. It is said that it's the first time he gets one. But in the season 1 finale, "Beauty Knows No Pain", Magnum's client Barbara Terranova commented that the message on Magnum's answering machine mentioned the club. (00:03:25 - 00:18:00)

Of Sound Mind - S3-E12

Higgins: How fiendishly deceptive of you, Magnum. I could have sworn I was hearing the emasculation of a large rodent. To my great surprise, I see the sounds are emanating from what I thought was a harmless musical instrument.
Magnum: Cute Higgins, real cute.
Higgins: Why Magnum? Why do this terrible thing?
Magnum: Higgins, I'll have you know I used to be very good. I was the second best sax player in my High School band!
Higgins: Well, how many sax players were there?!
Magnum: ...Anyway. I just saw this in a pawn shop window and thought I'd like to try and get my chops back.
Higgins: May I suggest that your "chops" are irretrievable.
Magnum: Higgins, did you come here just to abuse me!?
