Continuity mistake: During the scene when Higgins comically 'abuses' Magnum and his sax skills, the shadow of the instrument on Magnum's chest changes position depending on the angle of the camera. Moreover, when Higgins mentions he came "on two accounts", Magnum tilts the sax back two times in two separate movements. (00:05:50)
Continuity mistake: The first time we see the blonde cousin, she is holding in her arms the picture of dear departed. Cut to a view of the room, and her right hand is at the top of the frame, completely different position from before. (00:08:00)
Continuity mistake: After a breathtaking rendition of "Silent Night", Marina sits down. Next to her Simon is on the couch, who stretches his left arm placing it along the back of the couch, and the right arm goes on the armrest. Yet in the next shot he has both hands in his lap. (00:08:45)
Continuity mistake: When a subservient TC grabs Magnum's suitcase, the torn-up gas bills move from his left hand to his right between shots. (00:22:15)
Continuity mistake: Magnum gives Marina the glass of scotch. When she nervously laughs saying "We all did", she is holding her glass with one hand; in the same shot, the other hand joins, but in the reverse shot it's not there, and back there as it returns to the previous angle. Moreover, the forefinger is at different heights in the separate shots, as shown by the level of scotch. (00:26:15)
Continuity mistake: Marina does a Bette Davis on Magnum and then turns around to leave. She stands in the middle of the entrance, with still her glass in hand. Quick cut to Magnum, and the glass conveniently disappeared. (00:26:55)
Continuity mistake: Magnum hears a noise at the bottom floor and starts walking downstairs. In the shot right before the close-up of his foot breaking the step, at the top of the stairs you can see some candles he was not carrying and are not consistent with the illumination of the scene - in fact you can see Magnum with candles only in a brief shot in the 'teaser' before the opening credits, in a scene that was left out of the episode. (00:28:40)
Continuity mistake: At the entrance of the masquerade, in the close-ups of John Hillerman (starting when he says "However difficult this may be to say") you can see Carlton in the background, which is incoherent with the reciprocal positions in the shots of the hall. (00:31:40)
Continuity mistake: When the Grim Reaper closes the safe, in close-up his hooded head casts a shadow on the door. Cut to a wider shot, and the shadows changed. Likewise, in this wider shot he puts the painting back in place and the scythe casts a very oblique shadow, but in the shot when he reacts to Sir Thomas' arrival the shadow is vertical and his head casts a visible one too. (00:34:55)
Continuity mistake: In the epic clash between Canned Magnum and the Reaper, Magnum falls on his back and the sword falls back on his arm. When the Reaper walks past him, the sword is on the floor by his leg, but it goes back to the precarious position on his arm when he is flailing his arms crying for help. (00:35:35)
Continuity mistake: In the hilarious stretched out comedy scene with Magnum trying to chase the suspect in his armor, whenever he is shown charging at the door and eventually breaking in, he is wearing the sword that he never retrieved - and in the moments when it's Tom Selleck in the armor and not a stuntman, he is not wearing it. (00:37:00)
Continuity mistake: When Wilson MacLeish is kneeling on the golf course, the light changes drastically between close-ups (shadows) and wider angles (strong sunlight on the chest). (00:45:10)
Continuity mistake: In the finale, the wet stain on Mr. MacLeish's body changes between the close-up and the wider angle. (00:47:15)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: When Magnum protests that it is in his "constitutional rights" to bug-spray the lads, his hand is on his belly, but it is on his thigh in the wider angle that follows. (00:05:00)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: At the beginning of the scene at the King Kamehameha club, Rick and TC are laughing their pants off at the whole ninja story. Magnum says "Come on, guys!" and two people - a woman with a blue swimsuit and pareo and a man with a purple tanktop with a large light strip - are moving across the street. Those same extras are recycled later in the scene, simultaneously by the sea when Magnum's story is called 'a little far-fetched' and walking in the club area right after. (00:15:30)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: When Rick goes "Hohohohoho!" at Magnum's "I need your help!" passionate plea, both him and TC are sitting in different positions compared to the previous shot - they had their hands in midair and now they have them placed on the table. (00:16:10)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: After waking up with a massive hangover, Magnum is meeting the unhappy designated recipient of the Kenzan plate. At the beginning of the convo, the table shows no direct sunlight, but at the first cut the scene is suddenly brightly lit. (00:26:40)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: During the car chase, the weather changes from one shot to the next - the pier is fully and brightly lit, when it wasn't a moment before. (00:33:00)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: Magnum dives fully clothed to save Gallagher, the Tourist Shop Owner. Obviously he's soaking wet after that. Later at home, Magnum is sitting at the desk in the study wearing the same polo and jeans, bone dry. (00:35:00 - 00:36:10)
The Arrow That Is Not Aimed - S3-E13
Continuity mistake: After Tozan has finished everyone in berserk mode, the dead ninja closest to Magnum is lying down in different positions between shots. (00:43:15)
