Continuity mistake: Magnum takes a bottle of the infamous Coops beer from the fridge and puts it down while Higgins is doing his threatening smile routine. He puts it down with the label facing away from the camera. When he answers the phone, the bottle is again facing away from the camera, but the angle is the opposite than the earlier one. (00:13:10)
Continuity mistake: The threat about the Romanian mime troop does the trick, and Magnum stands up to go after Higgins for some begging. The cloth he's cleaning the crossbow with dangles in its length in the first shot, but it's draped over the handle in the next. (00:14:00)
Continuity mistake: Magnum's search for clues at Marcus' is interrupted by a banshee scream from the girl with glasses. In the first few shots of the sequence, Tom Selleck's left arm is never in the correct position, being low in frontal view and raised in reverse shot, doing the same movement twice in different shots, etc. (00:09:05)
Continuity mistake: Magnum follows his inner voice and gets inside Marcus' quarters. The camera follows him and he stops in front of the desk where a picture is balanced on one side on some stacked papers. In the close-up that follows, the picture is flat on top of Marcus' appointments book. (00:08:45)
Forty Years from Sand Island - S3-E17
Continuity mistake: Magnum approaches the Nakamura house getting out of the car with light beige shoes. The young and pretty granddaughter of the deceased walks him around the corner, to her father. In the scene with Russell Nakamura, Nancy's Father, Magnum suddenly has dark brown moccasins, which you can see when he walks towards him and then away. And then when Nancy walks him back to his car, the beige shoes are back. (00:20:10)
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
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
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)
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
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)
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)
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)
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)
