Continuity mistake: Magnum creates a Rodin-esque stack of beer cans. His store manager lambasts him, and when they are looking at his creation, it looks different already - the can he put on top as finishing touch is missing, immediately noticeable. (00:02:15)
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)
Continuity mistake: Magnum escorted the two old ladies at the Fointanbleu Residence. The one in red, Madge, has her hand on Jeanie's arm when she says they were actresses, but she kept her hands to herself in the previous shot. (00:07:25)
Continuity mistake: Magnum is at the old ladies' residence and is talking with the card collector. In the close-up of the baseball broadcast, the object on top of the TV are gone. (00:08:45)
Continuity mistake: After the garage fiasco, Magnum sits down with the ladies who patronize him. During the scene, the sunglasses retainers run to the inside or the outside of the shirt collar, depending on the camera angle. (00:13:05)
Continuity mistake: Higgins mocks "Tommy", who in close-up rips the page of the notepad where he scribbled down the partial license plate. In a wider angle a few seconds later into the verbal exchanges he rips the page again. (00:18:05)
Continuity mistake: Magnum sits on the couch's arm, by one of the sisters who is holding Higgins' book in her lap. On her lap, under the book, there's the handkerchief she used when she was having tea. In the closer angle, there's no hankie, while Madge's is open wider. (00:18:20)
Character mistake: Magnum is holding a stinky pickled egg while he bickers with his friends in Rick's car. TC calls the store chain Magnum has been hired to protect "Day-N-Night" instead of "Day-N-Dark." (00:22:00)
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)
Visible crew/equipment: At the bingo fundraising event, in the shot from behind TC as he hands someone a few bingo cards, as the camera moves backward two white tape marks are visible on the grass. (00:30:45)
Other mistake: Magnum rewinds the answering machine tape hitting the opportune button just once, and it plays on its own the exact bit he needs to listen to, without any intervention on his part. (00:36:20)
Character mistake: Higgins remembers having met the sisters "37 years ago this July", and shows a "theatre program from Blackpool the summer I completed my upper second at Sandhurst." Considering the episode is set in 1983, Higgins would have still been in military academy in WW2, which contradicts the plethora of experiences in North Africa and Burma. It's more likely that John Hillerman misspoke and it was meant to be "47 years ago", before the war. (00:37:30)
Visible crew/equipment: Magnum stops in front of the bar building on the beach of the King Kamehameha club asking his friends about his odds. They laugh him off, of course. In Tom Selleck's close-ups you can spot in the sunglasses TC's reflection far in distance with his yellow polo, but there's a man standing much closer that shouldn't be there. (00:04:10)
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)
Continuity mistake: Higgins outside the British shop is stammering. He says "But I..." and a blonde with sunglasses and a hair clip quickly walks behind him - nobody was walking towards them from that direction in the establishing shot. When a wider angle is again presented, there she is; that woman is approaching from that same direction. (00:07:15)
Audio problem: The woman Higgins seems to have developed an insta-crush on is dragged by two guys in an alley. She is protesting with rather high-pitched shouts but her lips do not move. (00:07:50)
Continuity mistake: Magnum approaches Vivian and Higgins' table carrying an oar; during this wide shot the table has direct sunlight all over, but in other camera angles they are in the shade. (00:10:55)
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)
Continuity mistake: Magnum speaks to Higgins in the study after the romantic dinner mix-up. The collar of his jacket is straight all the way up in wide shots, and loose in Tom Selleck's close-ups. (00:27:40)
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)
