Continuity mistake: When Dorsey pops pills in the tub with Magnum, he puts the bottle to the left, off frame. Mrs. Greeley arrives, and now the pills are on the opposite side, between Magnum and him. (00:24:25)
Continuity mistake: In the hot tub scene, Mrs. Greeley blackmails Dorsey in return for favours; during the conversation, David Wilson's mouth position/facial expressions transition from shot to shot with a spotty continuity all the way through. (00:25:00)
Visible crew/equipment: Higgins is walking the lads through the now oh so empty estate; when the camera pans all the way back, to the right of the frame you can see there is in fact someone else in there; it is the animal trainer who gives instructions to the dobermanns. (00:26:50)
Continuity mistake: At Mrs. Greeley's, Magnum says "He's not in bed", while she has both hands around her glass. She replies, icy "Wanna make a bet?" and it's just one hand. (00:30:15)
Other mistake: Someone shoots in the dark at the trio in front of the sandal king's house. Former Navy Seal Magnum must have read the script and know that the assailant was only gonna shoot once, because he jumps up from his sitting position and just stands there looking pensive at the bushes like a complete fool, taking no cover, nor trying to protect his client while the wife is dead. (00:33:20)
Continuity mistake: The security guard spots the obsessive fan running through the seats. He shouts at him, and in the next shot the guy is running a couple rows lower than he was in the first shot. (00:37:45)
Continuity mistake: The policeman gives Dorsey a picture of the crazy fan. Dorsey picks it up from the left side, but he's holding it by the bottom in the next shot. (00:39:10)
Character mistake: Higgins' anecdote inflicted on Rick says that In Kwangju. In '49, Corky Boswick got kicked in the head during "Sunday of the Queen's birthday party", but at the time, George VI was still King, and would be until February of 1952. (00:42:25)
Continuity mistake: In the tunnel, TC says "Bye!" to Magnum who tries to involve him in the finale; the number 33 player is both behind TC and behind Magnum. (00:44:25)
Visible crew/equipment: While Eleanor Greeley is holding a gun in the training room, Magnum realises that she's holding a .32, then in the next and following shots two black tape marks are visible on the floor. (00:45:30)
Continuity mistake: Opening scene, recycled extras. Look no further than the blonde woman in a maroon stewardess uniform, walking to the left of the screen in the suspicious person POV, and simultaneously in the background behind him. Or the woman with long curly hair wearing a brown top and long beige skirt. (00:01:50)
Continuity mistake: The man running down the escalator runs past the same couple (old lady with blue dress and man with pale yellow shirt) twice. Similarly, when the policemen reach the top and shout "Halt", the same woman with a hat reaches the top too in two separate shots. And, in the same shot, in the foreground coming up from the escalator there's a man with a white and blue striped polo, who was visible earlier in the policemen's way when Mike Vejar's director credit popped up, on the way to get down the same escalator. (00:02:15)
Continuity mistake: Magnum joins TC and Rick that are playing poker with a mysterious blonde. As he gets through the door, the towel around his neck has the left side pulled very much up, above the level of the 44 symbol on the tanktop. The towel drops lower (more balanced) in other shots, going back and forth between the two levels. (00:04:00)
Continuity mistake: Rick looks at Magnum funny when Jeannie Lowry says he'd look devilishly handsome in a tux. He has cards in hand, but the next shot starts with no cards anywhere near (TC is just then shuffling the deck), and more discontinuities happen during the convo later. (00:04:30)
Continuity mistake: In the close-ups of Jeannie's hand with the face-down card dealt by Mr. Matt Thompson, you can spot to the left of the cards her handbag, which is way far away in the shots of the table. (00:10:30)
Visible crew/equipment: At the end of the poker game, Thompson loses his last hand and he slams the cards onto the table, then when the camera turns to face all the players, the black tape mark can be seen on the floor where Magnum stands. (00:15:20)
Visible crew/equipment: After Thompson asks JL and Magnum to accompany him to his cabin to get the money from his safe, just as Thompson opens his cabin door, the white T-mark is visible on the floor beside the desk, which is where Magnum stands. (00:15:45)
Continuity mistake: Magnum is catching his breath while the guy who was having the better of him has to stop being held at gunpoint. He is touching the guy's arm in the first shot, but has his hand on the armrest of the chair in the next. (00:17:05)
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)
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)
