Revealing mistake: Magnum goes through his collection of Topps baseball cards; the fake one with Johnny Wells has a design that sticks out from the others - it is in a fact a 1969 Bernie Allen one with a little post-it sticker on it with a different name. (00:25:25)
Revealing mistake: In the prolonged close-up of the London Chronicle it's easy to spot the same two paragraphs repeated over and over in the main article. Someone at the prop department was particularly lazy - although they did put in some pretty funny gag, because at the very bottom you can see an ad for "500,000 slaves at 1£ each." Pretty sure that was not allowed on British newspapers in 1983. (00:05:45)
Revealing mistake: Higgins puts on the table the newspaper clipping with the picture of Lady Wilkerson. The text underneath it speaks of a generic conference, and it's simple filler text he had no reason to keep. (00:15:45)
Revealing mistake: When the kidnappers drive-by ending up hitting with the car door, John Hillerman is replaced by a stunt double with hilariously fake moustaches, and Magnum is not Tom Selleck. (00:29:00)
Revealing mistake: A younger and more athletic stunt double for Higgins is visible in several shots of the climactic fight scene at the end of the episode; when he dodges the first punch after tossing the jewel appraiser in the water, when he gets slammed back-first against the crate, when he pulls the rope and so on. (00:40:15)
Revealing mistake: Higgins disposes of one of the evil dock workers by letting loose a lot of barrels, but it's very visible that the man falls on his own in the way of the barrels for that stratagem to work. (00:40:50)
Revealing mistake: When Higgins KOs the main villain, two mistakes happen; first of all, the one already down for the count is buried in drums in a different way than shown before, and second and funnier, the stuntman who takes the fall from the pier is either wearing a wig or has a natural poofy head of hair - in either case, it's dry hair and not the wet thinning hair of Terence Knapp crawling out of the ocean. (00:40:55)
Squeeze Play - S4-E7
Revealing mistake: When Lola hits back Rick's pitch and gets him in the 'nads, it's transparent in the shot of her swing that the ball was not flying back at the pitcher in a million years. (00:10:55)
Squeeze Play - S4-E7
Revealing mistake: The construction workers in the bar believe Magnum's bluff about being an inspector, and make a run for it trampling him. Tom Selleck's stuntman is the one taking the risk of having a mob of big guys stomp him - and you can actually spot a fake moustache dangling loose during the action. (00:18:30)
Squeeze Play - S4-E7
Revealing mistake: Higgins speaks with the idiotic nephew of the most hated (temporary) new boss, who tells him uncle is in the Den. Higgins opens the door and before it cuts to the new scene, you can peek through the door and see that the lights are switched off; Higgins is walking into an empty room (would be fun if it were the broom closet, but it's actually the correct photoset, just with nobody there). (00:19:25)
Revealing mistake: The shot of the Ferrari during the directorial credits (filmed from a car in front) does not feature Roger E. Mosley behind the wheel; you can see a bit of longer hair sticking from the top. (00:04:30)
Revealing mistake: During the crash through the fence, the front of the Ferrari has a mockup in the front; the left direction indicator falls off outright, but it is just broken when TC and the new two passengers take off. (00:04:40)
Revealing mistake: TC's accident with the hog pen is shot in (at least) two takes, one with the stuntman dodging the car inside an otherwise empty pen, and the establishing shot with the animals when the car is still not so close - and then when the car has stopped at the end and there's no danger for the pigs. (00:04:40)
Revealing mistake: When the brawl in Charlie's office begins, Tom Selleck changes into his stuntman who can be seen as he quickly stands and punches a goon. (00:41:50)
Revealing mistake: All the 'boxing' in the episode is unrealistic pure 80s Hollywood hot camp garbage, but the finishing blow of the final match in particular is miles off, bad even for the low standards of that sort of 'action'. (00:44:10)
Revealing mistake: The closing shot of the episode shows the lookout point platform where the suicide attempt happened...but also, below it, you can catch a glimpse of an additional platform, and a rope probably used for safety reasons as well. Needless to say, it was not featured in the dramatic shot of Holly looking down into the abyss. (00:46:55 - 00:47:40)
Operation: Silent Night - S4-E10
Revealing mistake: When Magnum and friends sing "Silent Night" at the end, fake starry night background and dry ice clouds are perfectly discernable. (00:46:00)
Revealing mistake: When Danny runs away from the baseball field, the camera pans towards the left and stops while several people in the fictional Jororo army uniform storm the area on foot and jeep. But to the far left in the distance, you can spot a legit Hawaiian cop at the roadblock used to film freely in the street. (00:02:35)
Revealing mistake: The prince runs away from the game and into the market, where army people on jeeps chase him. They crash goods, topple carts and all sort of destruction, but the extras in the market are actually having a great time and most of them just laugh while people with automatic weapons shove them aside and spill on the ground their stuff.
