Continuity mistake: At the end of the episode, Magnum manages to show up for the bridge game. He opens the gate and closes it behind himself; he makes the appropriate motion and there's even a wooden clunking noise. Still, in the shot that follows, the gate is wide open. (00:47:35)
Continuity mistake: Magnum does not realise he's been tailed, and goes to pick up Kiki as promised. He picks her up at a bus stop...but the bus stop sign is gone at the first cut. (00:33:40)
Continuity mistake: Magnum walks back from his swim and approaches Apollo (or Zeus) holding a pair of flipflops in his mouth. There's another large and smooth shadow to the left of the dog in the first shot, not making an appearance in Magnum's POV. (00:17:45)
Continuity mistake: Rick spots Higgins at the club and tells Magnum to hurry up. He is wearing his ring and a bracelet on his right hand. When Higgins leave, it's the same, and you can even see he's wearing a watch with a leather bracelet on his left wrist. But then Magnum leaves too, and in the very last shot of the scene all the aforementioned accessories switch side. (00:29:10)
Continuity mistake: Shot from the waist up, Maku is wearing a bracelet on his left wrist and quite a lot of his soaking wet hair trapped under the towel he has across the shoulders. He then makes his way to his camping chair, and he has no bracelet and his hair drier and off the towel. (00:13:35)
Continuity mistake: After Kiki says that Maku bodysurfs "whenever he feels old", you can spot in the footage of the man in the ocean that he's wearing fins at his feet. Maku emerges from the ocean cool as a cucumber but with no fins. (00:12:50)
Continuity mistake: When the judge asks Magnum "Take me back to my hotel", in the background there's a woman in a blue pantsuit and there are people by a large building entrance she's approaching. Switching to another shot, and all of that is just gone. (00:24:40)
Continuity mistake: Magnum responds "Trust me" when Rick reminds him he's not driving the Ferrari. What follows is a close-up of Dutch, driving a right-hand car - shot has been flipped in post. (00:46:00)
Continuity mistake: During the knife fight, people appear and disappear between shots from the flight of stairs outside. (00:27:40)
Continuity mistake: Judge Robert Caine comes out of the hotel while Magnum is munching Higgins' lunch and reading the articles. A couple (she wears purple) walk by him. Magnum spots him and scarfs down the last bit of the sandwich, closes the bag, starts the car; a good 30 seconds passed before he's out of of the parking lot, and yet next time the camera goes back to the judge, the couple from earlier is still passing him by. (00:21:40)
Continuity mistake: Magnum walks up to his client, waiting on the beach in a suit. He tells him he's flattered; José Ferrer's arms are folded, at the cut they are down his side and only then he folds them. A very similar flub happens seconds later; he pulls the letter out of his pocket, and does it again in reverse shot. (00:07:05)
Continuity mistake: In the intro, Bobby holds Diane telling her nothing will go wrong - last famous words. Between the first shot and the close-up, her hair changes position on the shoulders, and when she hugs him, her hand is off and on his shoulder at the cut. (00:03:55)
Continuity mistake: For the final confrontation with the rogue Delta agent, Magnum moves from the van where he (foolishly) left unguarded the bad guy with the damsel taking cover behind one cable drum, to another. He looks back in a close-up as he clings to the drum, and the van is far in the distance behind another drum. He then looks forward, towards the tower where the agent Tobin is hiding, and decides to move. Only, we see that his sortie is beginning from the large spool the van is parked next to. (00:42:50)
Continuity mistake: When Agent John W. Newton is shot to the shoulder, he drops his M-16 behind him, a couple meters above his head. Magnum retrieves it from the vicinity of his foot. (00:46:00)
Continuity mistake: Magnum runs away from Tobin's fire, ducking by a large piece of construction equipment. In the closer shot that follows, that element casts a large shadow Magnum repairs in, and that was nowhere to be seen earlier. (00:43:20)
Continuity mistake: Higgins and the other higher-ups at the King Kamehameha Club march towards Magnum after the shooting incident. Their positions change between shots - Rick's thumbs move from the belt to his front pockets and the guy with the powder blue jacket is behind the guy with the mustard one. (00:26:05)
Continuity mistake: When Magnum stands up telling Newton he wouldn't give him the directions to Diamond Head, Rick in the background is leaning against his right hand in the first shot and has both hands on the file in the second. (00:22:55)
Continuity mistake: After telling Agent John W. Newton to "go suck an egg", Magnum walks away...but no so far, because he is leaning against the railing just across. His right hand is far away from the vertical beam in the first wide angle, and on top of it in the next closer view. (00:23:00)
Continuity mistake: Magnum explains that the "delta section" of the US Army does missions involving stuff like sabotage, assassination, terrorism (!). Laura protests saying "Eric couldn't have been a part of anything like that." She says it with hair in front of her right shoulder, in contrast with the previous shot. It switches back and forth again with the change of angle. (00:12:10)
Continuity mistake: Laura tells the story of the 'visions' she has of Eric Tobin. More and more engrossed, she says he keeps "falling and falling." Her long mane is off the left shoulder. Cut to Magnum for a second, and she's got hair everywhere around her face, only to have again face and shoulder clear of hair in the next change of angle. (00:09:10)
