Forty Years from Sand Island - S3-E17
Continuity mistake: Nancy Nakamura steps away from Magnum telling him she "did not have to decide." Her hair is fully combed back. She is briefly out of frame, and Magnum walks back to her without her moving, but her hair is now cascading all over her shoulders. (00:39:00)
Forty Years from Sand Island - S3-E17
Other mistake: Hank Palmer appears in the closing credits as "Hank Sorenso", but his last name is pronounced by everyone (and logically so) as "Sorenson", and Rick says his first name is Fred. (00:31:00 - 00:48:00)
Forty Years from Sand Island - S3-E17
Continuity mistake: Magnum sits down with Saichi Goto leaving the girl on the pier. He asks him "what do you remember about 'em?", and holds his left hand with his right. Reverse shot and it's the other way around. (00:26:10)
Forty Years from Sand Island - S3-E17
Revealing mistake: Magnum usurped Higgins' desk while he's at the hospital. He is checking out of the article about Enoka running for Senate. If you look at the first article on the left, it begins with "The facts regarding the situation remain the same, state the authorities", the famous filler text that appears in dozens of props made by Earl Hayes Press. (00:16:35)
Forty Years from Sand Island - S3-E17
Continuity mistake: In the flashback, the one who supports Mr. Nakamura's head does it with the thumb raised above a cone of shadow and clear of his chin in close-up, not matching the previous and following shot. (00:04:30)
Character mistake: Bickering with his pretend wife after risking his neck with the falling crates, Magnums says "we can stop playing house, I can go back to being a private detective, which is exactly what I should have been in the first place." Magnum has a verbal tic during the series and he fiercely corrects everyone when they call him a private eye, or detective, as he goes only by "investigator" (the I in P.I, after all). He's using the wrong word here. (00:22:35)
Forty Years from Sand Island - S3-E17
Continuity mistake: In the confrontation at the pier at the end, wind blows through Andy's hair more when he is shot from behind, less from the front. (00:40:30)
Forty Years from Sand Island - S3-E17
Revealing mistake: When Magnum rolls slowly in pain after being hit by the first box, and then when he rolls quickly to 'avoid' the others, his lab coat appears to have protective padding; there's a rectangular shape sticking out. (00:21:25)
Forty Years from Sand Island - S3-E17
Continuity mistake: Magnum's wife makes him lie down again on the office couch. His tie runs down his left side with both ends when the camera is behind his head, one to the side and one straight in the other view. (00:23:20)
Continuity mistake: When Magnum encounters his secretary and he just won't let go of her hand, in the frontal views of Tom Selleck he has his fingertips curled, while in the reverse shots the fingers are straight and don't rise above the side of her hand. (00:19:00)
Other mistake: Marsha Mackenzie is supposed to be competent with certain aspects of men care; she comes from a wealthy family and she has been taking care of the men in her family all her life. And Magnum does show up at the Kamehameha club with a nicely done knot on his tie. When we actually see the actress tie that same not metaphorical knot though, it's very clumsy, crooked and differs in between shots (it's also done on an unbuttoned shirt).
Continuity mistake: Harry MacKenzie gets two big splotches of cake on his suit. Dances with his niece, and then comes back to the buffet table taunting his nephew. No (or at least, very little) splotches at first, but in the closer view his suit is all soiled again. (00:06:20)
Continuity mistake: Rick and TC are at the wedding buffet. Behind them as they toast in memoriam of Magnum there is a dancing couple. She has a pink hat and her date has a yellow jacket. There's also a black guy in a brown jacket busting some groovy moves of dad dance. Both are also behind Higgins as he arrives, though. The couple also walks back and forth padding the background in the rest of the scene. (00:03:50)
Audio problem: When Higgins lists the various things he expects to run into when he enters' Magnum mancave, there's a noticeable difference in the ambience of the audio when it cuts to Magnum as he mentions the "soiled garments."
Continuity mistake: Magnum pours champagne for Miss Elizabeth Barrett, and finishes the bottle. The cloth around the bottle falls off, but it's neatly arranged around it again in the wide shot that follows the reaction shot on Higgins. (00:14:05)
Visible crew/equipment: When Tom Selleck's wife is driving off at the end of the episode, equipment and lights are reflected in the side of the car. (00:47:30)
