The Taking of Dick McWilliams - S2-E9
Continuity mistake: Rick is on the phone with "Shakey" while TC, who spotted his black eye, is pestering him about it. Rick's hand with the piece of paper changes height between shots. (00:22:10)
The Taking of Dick McWilliams - S2-E9
Continuity mistake: When the chopper follows the group of cars, their number changes between shots (5 in the widest aerial shot, 7 from the camera car). (00:19:00)
The Taking of Dick McWilliams - S2-E9
Continuity mistake: In the tunnel scene, the shadows at the end do not match -at all - between the different angles - in fact, the whole road is different, it's now more of a mountain road, the other parallel street disappeared. (00:18:00)
The Taking of Dick McWilliams - S2-E9
Revealing mistake: In the shot meant to show TC's chopper coming near the tunnel exit, the movement is not consistent with the handling of the chopper, not even within the maneuverability of it. (00:18:00)
The Taking of Dick McWilliams - S2-E9
Continuity mistake: In the wedding night flashback, Mitsu puts her hand on Dick's chest, with the fingers that either poke above the undone tie, or don't, depending on the angle. (00:13:30)
The Taking of Dick McWilliams - S2-E9
Continuity mistake: In the hotel suite, Dick says "I bet you that the bed is round" etc. Mitsu puts her right hand on top of the left looking at him and listening. Close-up, and it's the other way around, it's the left on top. (00:12:10)
The Taking of Dick McWilliams - S2-E9
Continuity mistake: Magnum is busy doing his taxes with TC on the couch when Higgins arrives. Throughout the scene, the position of Magnum's calculator on the table changes between shots. (00:05:30)
Continuity mistake: Magnum is pouring sweat at the beginning of the episode, with a huge sweatstain at the front of his tanktop. He's wearing the same one when he talks to his client, but it's all dry. (00:03:00)
Revealing mistake: Magnum just set foot in the bar, and finds TC and Rick there. Buck puts the crutch against the back of the couch, but it won't stay still, so Darren McGavin tries again. This time, a stagehand just out of frame catches it and draws it out of frame. (00:19:40)
Visible crew/equipment: Gibson crashed the Ferrari into the goat fence. Magnum stops the Audi and walks out to help him. Inside the passenger side mirror, the hand of the cameraman can be spotted. (00:34:55)
Other mistake: Magnum needs to stop Buck, and asks Higgins for the keys to the Audi. Higgins just happens to have the keys in his pocket, which makes no sense, since he keeps them in a drawer inside the study, and can't just wander about all day with all the keys to all of Robin Masters' vehicles inside his pants. (00:33:00)
Revealing mistake: When he trades some punches with the big guy in the bar in a fast paced sequence, back to the camera, "TC" is a good 20 pounds lighter. (00:23:05)
Continuity mistake: In the barroom brawl, Rick foolishly attacks the huge dude. He backhands him into oblivion, sending him falling back-first off frame. Rick crashes on the stools belly-first though, and the stools were at very short distance, not exactly room for him to turn another time and fall as shown. (00:22:55)
Continuity mistake: Magnum stares wide eyed at Buck and his target practice in the bathtub. In the shot of the room, you can see in the head area of the target already a soot mark where the extra hole will open later - and there is no trace of it in the opening close-up. (00:14:55)
Audio problem: Mrs Joan Gibson, shoes in hand, is waiting for Magnum after his surfski session. He tells her "I'll be honest with ya" and there's a cut. The audio quality in this second part of the conversation takes a dive for the first seconds before finally adjusting. (00:12:25)
Continuity mistake: Higgins and Agatha fall down in the longshot facing the same direction, but when Mad Buck sits up and puffs, they are facing each other instead. (00:07:30)
Revealing mistake: Mad Buck lands on Higgins' beach croquet course, and right on him and Agatha. The two are replaced by obvious stunt people, though. Higgins' definitely has more hair than John Hillerman, and the woman is younger than silver fox Gillian Dobb. (00:07:20)
Audio problem: Higgins interrupts Magnum when he's about to go paddle in the ocean. John Hillerman's voice is dubbed over, and it's easy to tell because the background noises almost disappear during his line, to resurface when he's done. (00:02:15)
Wave Goodbye - S2-E7
Character mistake: At the station after the release of the first suspect, Kelly does the good cop routine and apologizes for his Sergeant, saying he does not like a private eye telling him how to do his job. Magnum 99% of the time during the show corrects people saying "private eye" with "private investigator", but here, he does not. (00:16:20)
Wave Goodbye - S2-E7
Plot hole: For two patrol officers (one of them being kinda green) in Honolulu, Kelly and Jordan sure seem to have the weight of the entire State on their shoulders; they also investigate extensively the murder case, and they, until a month before, "worked drugs in that area", which was a piece of jungle around Maui. It's like the department for this episode and this episode only has no detectives, and a couple of random beat cops are covering the archipelago with highly specialized duties.
