Other mistake: Magnum runs away to chase the sniper. A few extras promptly start yelling and screaming despite the fact that from their position they can't have properly seen the victim of the sniper yet (and there's no blood). (00:14:50)
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.
Other mistake: Contrarily to what TC says, the alarm is not 'covered with corrosion', in fact it looks pristine. (00:16:55)
Other mistake: Magnum tells Higgins he has just twenty-three hours to solve the case when both the clock at the Nest and the one at the Honolulu Lulu's Pool Hall show it's half past four. Magnum though accepted Babs' case around 11:30 AM ("11:29 at the tone", Rick jokingly said). (00:07:35)
Other mistake: The license plate Magnum tells Rick to check out ("55 678") is totally different from the AYX 470 the guy was actually driving. (00:16:35)
Other mistake: The TV report about Magnum doing a Ready Player One backwards race, is shot from a perspective that would have required the cameraman to practically sit on Magnum's bike hitching a ride, in particular at the end. (00:48:25)
Other mistake: When Magnum sprints to the ocean at the end of the episode, his bare feet are remarkably clean for someone who has just run through a lawn freshly fertilized, with Higgins just shoveling it in his path. (00:47:40)
Other mistake: The episode opens with the Coast Guard finding the boat owned by Marion's father empty. It's a small sailboat. Later Magnum visits it with Marion, and the boat is a small double decker yacht that looks entirely different. (00:01:50 - 00:09:30)
The Woman on the Beach - S2-E3
Other mistake: First scene set in present day. Exterior shot of Rick's club. A sign says "King Kamehameha Club - Est.1905", In the previous season, episode 11 was focused on the club itself, and Magnum met the landlord, Mr. Sidney Dollinger, who explicitly said "I founded that club for the people.", and Magnum, regretting accusing him, mentions that he blamed "an 80-years-old man." Even assuming he was not precisely 80 in 1981, in 1905 he still would have been a pre-teen or barely a teenager, not the rich planter who founded Hawaii's most exclusive club donating a vast domain to it. (00:05:30)
Other mistake: The commanding officer to enter the control room passes in front of two signs which, even with different sizes, say the same thing - but the one on the wall mentions a "Wheeler airbase" (which actually exists), the one on the door a "Delber". (00:02:00)
Other mistake: In the opening credits, Clyde Kusatsu is listed as guest star playing "Colonel Ki." However in the end credits Robert Inouye (should be "Inoue", really) is "Colonel's Ky's driver." Ki seems a more plausible spelling, but it should be noted that in the actual episode, during the meeting when the Americans ask the General about returning the bodies buried in 'Nam, the nameplate of the absent Colonel says "Col. Ky Lan." (00:01:55 - 00:31:25)
Other mistake: In the scene in the study at the beginning of the episode, Magnum just ran from the ocean to the house, but his swimming trunks are barely wet at the border of the leg. (00:05:40)
Other mistake: The sunset Magnum comments on and is featured in the opening shot of the scene has nothing to do with the actual light of the rest of said scene. (00:08:40)
Other mistake: The US delegation pops from behind some trees with military copters that are explicitly presented as deafeningly noisy; it's just silly and internally contradictory. Even if we forget how underplayed helicopter noise often is in Hollywood, here we go from zero to thunderous in a split second. (00:21:40)
Other mistake: Magnum and his bride seek shelter under table during the bombardment; if it happened the way it is shown, with a model completely torn to pieces, and with flames in frame during the first table shot, they would surely not be able to stay there, nor would have taken refuge there to begin with - if the roof did not kill them already falling on them. (00:25:10)
Other mistake: In the streets of Little Saigon in the climax with TC and Rick involved, you can spot the same passersby they met with Magnum a couple days before, same clothes and all. (01:30:35)
Other mistake: Colonel Ky fires his gun at Magnum a first time when he is picking up the handkerchief. In the background, a woman in brown is walking peacefully. Cut to scared crowd all over the place. Magnum turns the corner and from the new cover shoots a couple times at Ky. Next shot Ky returns fire, but it's just another take of the first shot; the woman in brown is again walking where she was, and reacts to the gunfight only at that point. (01:30:40)
Other mistake: Magnum messes up his clothes at the gas station, all covered in oil, and uses them to clean the windshield. Still, when the snotty Brit girl arrives, he recovers them from the passenger seat. That would have royally messed up the interiors, and Higgins right there would have freaked out, but neither happens. (00:11:00)
Other mistake: At the appointment / trap at the abandoned shrine, Magnum hears a bell toll. He turn around, and it's clear that someone rang the bell pushing the log - it is still moving, it's not an automated system and there's no wind. but since the plot does not involve it, he just goes on like nothing happened. For all he knew, it could have been exactly where his supposed client or informant wanted him to go. (00:18:00)
Wave Goodbye - S2-E7
Other mistake: When the bad guy pulls the gun on Magnum, the last twist is spoiled a minute too early if you notice the shadow of the actor on the right side, already standing by just out of frame. (00:46:40)
