Revealing mistake: In the first shot with Magnum on his surf ski, Tom Selleck is replaced by a body double whose face can be seen distinctly behind the large wave. (00:02:40)
Revealing mistake: When TC and the kids are watching the game live at the stadium, the film is much grainier making excessively obvious the usage of stock footage. (00:17:00)
Revealing mistake: When Magnum screams to attract Rick's attention and you can see the whole yacht, you can spot the real driver of the boat on the flybridge, not lit. (00:41:00)
Revealing mistake: During the big fight between the robed felon and the diminutive protagonist, the little guy is replaced by a stuntman in all the wider shots. (00:41:00)
Revealing mistake: When Magnum gives chase to the guy who took the elevator, you can spot Tom Lupo (Selleck's stunt double) 's face. He's the one doing the hard work of running down the stairs. (00:18:20)
Revealing mistake: When TC's chopper flies over the runaway jeep, "TC" piloting the heli is some guy wearing a black ski mask. (00:40:15)
Revealing mistake: When the jeep crashes flying in the air and rolling on one side, it is occupied by crash dummies, with blank faces and who flop lifeless out of the vehicle. (00:43:05)
Revealing mistake: At the very conclusion, the plane exploding has two sets of wings, not the Spitfire model that was supposed to be. (00:47:25)
Revealing mistake: When the kid skates away from the store after stealing the quarters, his hair changes from curly to a poofy straight bob. (00:04:05)
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)
