Audio problem: When Vivian tells Higgins "Will you visit me in England?" as the car takes her to the airport, a stock buzzing sound of an electric window is dubbed in, but look at Jane Merrow's shoulder; she's cranking the handle. Not quite the car for a Duchess. (00:46:10)
Plot hole: The plot of the episode is nonsense. The boss of the company knows that Magnum made no progress and is on the wrong track, since he suspects someone in Marketing - it should also be noted that Magnum is mystified knowing that the President has the access codes, but he himself has them, and it would be a given to learn who has the various codes as first thing in a security analysis like he conducted. Yet for a couple weeks this Prez guy sends his wife to just sleep with the PI's friend, for...no discernible reason, other than create a diversion he did not need and that hinges on events and reactions that non only he couldn't predict, but also have nothing to do with facilitating his espionage, considering also that a more competent security firm is hired right after. Likewise, why would the guy from R&D try to "scare Magnum off" doing an attempted murder that is sure to get him arrested when he knows Magnum is focusing on the wrong department?
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)
The Ugliest Dog in Hawaii - S1-E8
Other mistake: At the end of the episode, Zeus and Apollo are in a cage, and it is explained that it's because of sir Algernon's presence, due to Magnum's decision. It makes for a humorous finale, but does not make any sense; it's sir Algernon that has to be isolated for the 4 months quarantine, and an earlier segment implied that a fence had been built for him, as he needed to be limited in movements to avoid contact with the ocean and everyone on the estate.
The Ugliest Dog in Hawaii - S1-E8
Character mistake: Steve gets on Rick's truck and tells him "Just follow that car." However, when we see what happens through TC's chopper, the van is in the lead, and the car is the one following - probably it was footage shot with the intention to reveal Magnum's plan earlier. (00:42:00 - 00:42:40)
Other mistake: Erin at the beginning of the episode records her acting using a camera on a fixed support. She gets interrupted once. She resumes then. The camera angle is different, and then simply changes (as it's made clear by Magnum rewatching later the actual tape) without anyone else operating the camera.
Factual error: When Magnum looks at the collection of tapes and books from Erin, the shelves are stocked entirely with tapes marked L-250, L-500, L-750. A huge collection...for Betamax, but Erin's VHR player is a VHS, as shown by the logo in close-ups. And in fact, Magnum to watch her movie puts in close-up a T-120 tape in the machine, which is the proper format. (00:21:15)
Plot hole: Towards the beginning of the episode a peculiar arrangement is presented; Magnum has to share the guest house with two stewardesses, Mandy and Suzie. The night of the party, they both go for a swim. Mandy is involved in a shooting, and following scenes include her resting at the guest house. Suzie is never heard from since. She does not have a place to sleep; it is made clear that the main house has not been arranged yet for that purpose, the Brigadier and his escort have to leave first. She is not there in the morning. She just vanishes.
Other mistake: The photographer takes shots of the Brigadier on the balcony. The Brigadier is wearing a shirt and pants, fairly casual as expected. When Hooker is left alone in the dark room of the terrorist, he is looking at pictures of the Brigadier wearing a white jacket and bowtie, which is the outfit he will wear at the party several hours later. (00:12:30 - 00:25:35)
Other mistake: The creepy photographer guy is taking pictures throughout the episode. His camera somehow reaches everywhere on the estate; front gates, lawn, the Brigadier's balcony, with extreme close-ups and disregard to walls and structures in the way. It's one of those magic movie cameras.
Other mistake: The IRA operative puts the bomb into the Audi with a timer rigged for 5:00. Three minutes and a half of time that cannot be compressed (no cuts to any other scene that happens simultaneously - and if anything, more time than that should have realistically elapsed) pass before Magnum even gets on the Ferrari and drives out of the Nest. The way it is shown in the episode, Magnum could never make the heroic save. It gets even worse at the ending; 15 seconds remain on the timer and Magnum has yet to force the Audi down the beach road, the car has to reach the end of said road, Magnum runs, on foot, to their point, convinces them that there is indeed a bomb, and they run for cover.taking cover and waiting for the thing to explode! A minute could have been spent for that task alone. (00:39:20 - 00:42:50)
Factual error: The villain holds Magnum at gunpoint with a weapon with a silencer. Which is useless, the gun being a revolver. (00:41:20)
Factual error: Richard Johnson appears in the end credits as "Brigadier General Alistair Ffolkes, Royal Army", and is consistently referred to that way by Higgins and Hooker. The rank was abolished in 1921, the Royal Army would have him as as a Brigadier or a higher rank.
Other mistake: Magnum is taunting the dobermanns while he's grabbed and pushed against the door by two dudes. They are big, and armed. The room is normally lit. There is just no way he could get inside and somehow Miss their presence. Especially the one coming at him from his right; there is a railing on that side of the landing. Magnum would have literally bumped into him; it's not that because he was out of frame he was not existing. (00:05:15)
Other mistake: When the lads chase Magnum at the beginning, first of all they take a disproportionate amount of time to reach him, and secondly, the same footage is reused, so they effectively sprint past the same tree (with the same 2 dead leaves and straw by it) twice. (00:04:40 - 00:05:05)
Thank Heaven for Little Girls and Big Ones Too - S1-E4
Character mistake: Higgins is extremely protective of any little trinket and bric-à-brac at the Estate, but in this episode he barely bats an eyelid at a post-impressionist masterpiece being handled casually, rolled up and passed around. He handles it pretty badly himself.
Thank Heaven for Little Girls and Big Ones Too - S1-E4
Other mistake: Magnum gets inside the Waikiki Natatorium War Memorial climbing athletically over the closed gate. The bad guy comes roughly from the same direction, but given his physical state, one wonders how could he accomplish such a feat - it is conveniently kept off camera, but he comes from a direction with no gates. To beat him to the finish, Rick picks another direction entirely just walking around the bleachers! And they all end up at the same location.
Don't Eat the Snow in Hawaii - S1-E1
Other mistake: For the cool shot when Magnum smiles at the camera and then drives off (which will be used in the opening of the show for its whole run), Magnum unclips the detachable roof of Robin's 308 GTS and gives it a good push back. But it's not a retractable roof that folds in, but a Targa hard-top. So, basically Magnum just dumped a piece of Robin Master's fancy car in a random lawn somewhere near his estate, maybe even denting the rear of the car in the process as he carelessly shoved it back. That's inconsiderate even for Magnum's low standards. (00:06:10)
Don't Eat the Snow in Hawaii - S1-E1
Continuity mistake: In this pilot, Robin Masters' Ferrari does not have the famous vanity plate ROBIN-1 characteristic of the series. The license plate of the car is 56E-478 when first shown, but does not stay the same throughout the episode; when the two yo-yos chase him, the Ferrari's plate is the first one in the city, but 561-068 when they get near to the tunnel, and is back to 56E-478 when the bad guys destroy their (already banged up) car. (00:33:55)
