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: 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: 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: 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 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: 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: 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 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: 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: During Magnum's fight with the security guard, the guard sells the punch a mile before it hits, and in the end supposedly goes KO, but is still breathing hard and moving. (00:42:30)
Revealing mistake: In the car explosion, the dummy inside the car is actually quite well done, but the camera lingers too long on it giving away the complete lack of any movement before the blast. (00:27:50)
The Elmo Ziller Story - S2-E20
Revealing mistake: When Elmo gets bumped and tossed around by the bull, the stuntman is wearing thinner fake moustache than John Hillerman's. (00:32:55)
The Elmo Ziller Story - S2-E20
Revealing mistake: Magnum sits down with Elmo and answers that no, he has not had any breakfast. Before he breaks out in a "WHAT are you eating?" you can see John Hillerman failing to pick up anything with the fork but pretending to be eating anyway. (00:14:15)
Revealing mistake: To board the helicopter as it takes off is a stunt double with a bulkier core than Tom Selleck's and lighter brown hair. (00:39:25)
Revealing mistake: When the bad guys are in search of Magnum but have to get back to refill their tank, they are sitting in a helicopter on the ground, with the sky (where you can also spot a jet plane) totally unmoving. (00:23:50)
Revealing mistake: The sailor that Magnum KOs when the alarm rings goes down in the fakest way possible. With a long delay and cushioning his fall with his arms way early. (00:17:45)
Italian Ice - S2-E15
Revealing mistake: The 'mysterious stalker' is looking at Magnum opening the door of Ferrari for Margo, through a camera lens. When later we see the photo developed, it does not match that angle at all. (00:24:20 - 00:32:40)
Italian Ice - S2-E15
Revealing mistake: Magnum finds the unpleasant surprise of a large scratch on Robin's Ferrari. In close-up he runs his hand along the "bloody gouge", as Higgins later calls it, but it's a badly constructed prop; look at the turn signal, tiny and circular, nothing like the larger rectangular one of the car.
