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)
Revealing mistake: In the aerial shot of the helicopter signaling the death of Merlin, its registration numbers are mirrored. (00:45:15)
Factual error: Higgins frightens the parrot with his peregrine falcon call, and the parrot flies away. The sky is a fairly big place though, and TC's helicopter is far away, so the fact that it'd be sucked in (that's not how helicopters work), maimed and somehow explode in a puff of (clean) feathers that instantly and calmly float down is borderline cartoon slapstick. (00:45:20)
Revealing mistake: In the Birdemic-like scene when Magnum barely escapes with his life from a deadly parrot before Higgins squeals it into suicide, our hero has multiple bleeding from lacerations on his arms that disappear one shot later, leaving room to face laceration who disappear in the following scene. (00:45:15)
Continuity mistake: Emily reaches the end of the road and stops the Robin-3. The parrot climbs on her arm, the part above her elbow, but when she steps out he is on her forearm. (00:38:40)
Continuity mistake: After dinner and much champagne, Elizabeth Barrett is in the study. In close-up she puts to the side a page while she checks the left; in the following one the right hand, holding the page, is hovering. (00:15:40)
Continuity mistake: When Elizabeth tells Higgins that she'll be working nights in 'his' study and they may jog together, she holds the champagne bottle with a hand wrapped around its neck at a distance from the rim that varies between shots. (00:11:45)
Continuity mistake: Higgins is speaking with Robin's former teacher at the airport; she has her index finger outstretched in front views, curled in the respective reverse shots. (00:08:30)
Continuity mistake: A puzzled Higgins spots the drunk and disorderly Elizabeth Barrett sitting on the cart, champagne in hand. He greets her; when he states his actual name dispelling any rumor of him being a seagull, you can see a woman with a very colourful (rainbow, in fact) sweater walk behind him. The same woman passes another time, and is also at the conveyor belt, opposite side of the hall. (00:07:40)
