Continuity mistake: Inside Rick's room with both him and Mac waiting, Magnum pours his drink from the decanter in his right hand, and then left hand. (00:28:55)
Continuity mistake: Magnum and Kate have the "I am mad at you" "And I'm mad at you!" exchange. When the camera angle changes, the sheets in front of Magnum slid past the edge of the table a bit. (00:36:55)
Continuity mistake: Higgins' hand motion when he whips out of the cigarette case is incoherent between the various shots. (00:05:40)
Continuity mistake: When Magnum reports that he narrowed the possible spy candidates to those in marketing, his hands are crossed over - but in the next shot, he is crossing them again. (00:06:40)
Continuity mistake: Magnum and the corporate executive are having a chat after the board meeting. Throughout the scene, the same extras (starting with a man in a blue shirt and camel shorts, a man with a brown pattern shirt, a woman with a baggy sand dress) walk back and forth over and over in the mall or behind them at the tables. (00:08:00)
Continuity mistake: In the very brief dinner when Claudia tells Rick that it's over between them, she casts a shadow behind her in close-ups, all the way to the left in the other shots. The difference in ambient lighting of the whole table spot is significant too. (00:18:20)
Continuity mistake: Magnum is hunched over the Ferrari opening the door when the car first tries to run him over, but in close-up Tom Selleck is standing tall. (00:22:50)
Continuity mistake: Magnum is in James Randolph's office and 'the new guy' is talking to him. He says he disagrees on Magnum's hypothesis; in the transition both him and Randolph have very different positions, with Randolph's hand on the glass and arm raised differently, and J. Weston Reese's arms from crossed in front, to his pockets. (00:26:45)
Continuity mistake: Randolph puts the secretary on hold as Weston Reese tells him his plan to keep Magnum a target. Randolph's arm is in a different position on the desk depending on the camera angle. (00:28:25)
Continuity mistake: Higgins hobbles towards the club's beach bar in his horrid state (you'd think he wouldn't be caught dead looking so ridiculous) and starts reminiscing about the war and trying to mooch a cigarette. In the background, the same blonde with a black bikini hops over the wall twice, and same for the Asian with a blue/black swimsuit. Moreover, a girl in a red bikini and yellow towel keeps making back and forth walks by the surf on the beach. (00:29:30)
Continuity mistake: Rick tosses the lighter on the table when Magnum shows up tobacco-blocking poor Higgins. The lighter is in a spot on the table next to a paper cup that was never there and is gone after, and the lighter moves too. (00:30:45)
Continuity mistake: The husband of Magnum's client shakes hands with everybody; in the first shot his other hand is at his belt, it's in his pocket in the following. (00:08:40)
Continuity mistake: Dave drinks his glass almost reaching the end, but when Magnum pulls out of the gun, the glass at the edge of the table is half full. (00:43:00)
Continuity mistake: At the end of the episode, Tanaka approaches Magnum on the hammock and they have a chat. Sticking out from Tanaka's pocket, first his pair of glasses, then a packet of cigarettes for most close-ups, then the glasses again. (00:46:20)
Italian Ice - S2-E15
Continuity mistake: Magnum pilfers the car keys from the cars, but in the first close-up there's daytime light to the shot, nothing like the night setting of the rest of the scene. (00:02:30)
Italian Ice - S2-E15
Continuity mistake: Magnum shuns Katrina in her tennis uniform trying to plan his day ahead for him. He gets in the car, wearing his plain brown shirt and baseball hat. First shot as he drives to town, with the voiceover going "Other than being a bit presumptive..." etc, and the Magnum driving the Ferrari is hat-less and with a bright red Hawaiian shirt. Of course when he reaches the campus he's in the hat and brown shirt again. (00:19:35)
Italian Ice - S2-E15
Continuity mistake: Magnum drops by at the acting seminar his disgruntled girlfriend is teaching. The books on the table appear in different positions under the different camera angles. (00:21:45)
Italian Ice - S2-E15
Continuity mistake: Magnum asks the (moderately) jealous Hawaiian about the scratch on his car. The guy says he didn't do it because it's "not nice." Margo is moving her hand from the bottom to the top of the stack she's holding, but it's back in place at the bottom in the next shot. (00:24:00)
Italian Ice - S2-E15
Continuity mistake: When TC says "Okay, you're the boss!" to the mobsters in his chopper, the back seats are empty - he lost 2/3 of his passengers. (00:28:25)
Italian Ice - S2-E15
Continuity mistake: Margos asks Magnum "Who's that?" seeing the chopper fly so low by the villa. Magnum is mostly off-frame but you can see his arm reach up to do the gesture he actually does only in the next shot - reach for his Detroit Tigers hat. (00:29:25)
