Visible crew/equipment: While Karen is being harassed by reporters, Magnum drives up then rushes over to her and they hug. When the two walk toward the building all the reporters follow, and three T-marks are visible on the ground. (00:07:50)
Continuity mistake: Magnum is talking with the administrator of the hospital, Phillip Harriman. He asks him about Dr. Jorgenson. When Harriman answers, a rather conspicuous fella with a big head of curly hair walks into the building. When Magnum walks off at the end of the scene, he comes across that same guy, who again is entering the building. (00:11:35)
Continuity mistake: After his first encounter with the annoying reporter, Magnum is swimming. He is wearing blue swim trunks. The he emerges from water to get his towel and chat with Higgins...but his swim trunks are now light brown. (00:14:10)
Continuity mistake: After denying any rumor about any more Iron Man competitions, Magnum asks Higgins about Dr. Jorgenson. His left hand is wrapped in the bath towel whenever Tom Selleck is filmed from the front, but it's bare in the views from the back. (00:15:05)
Revealing mistake: When Higgins shows Magnum the article that (allegedly) manipulates his words to support the thesis that Karen was driven mad by 'Nam, the paper uses the famed recurring filler text that many Earl Hays Press papers use ("An immediate investigation is assured") that appears in dozens of movies. (00:15:50)
Visible crew/equipment: After Magnum deliberately makes a threat against the reporter on the beach, when it cuts to the estate Magnum walks over to Rick who's talking about the union guy, and the white T-mark is visible on the grass where Magnum had been standing. (00:18:45)
Revealing mistake: Magnum confronts on the beach the slimy journalist and he 'threatens' him. He then turns around to leave. Close-up on Reporter Eric Daniels and after a second you can see in the left corner of the screen a tiny bit of Magnum's maroon hawaiian shirt pop in view. He never left. (00:18:50)
Visible crew/equipment: While Karen is packing up her car Dr. Jorgenson walks over to talk to her, and he begins by saying that he had spoken to her friend. Just as Karen says, "Thomas," in this shot we can spot something covered with black cloth and tape, presumably the boom mic, hovering low between them. (00:25:50)
Continuity mistake: To get to the pool area, Magnum slides a door open to the left (of the screen). When he finds the body floating in the water, the underwater camera shows the background, and the door opens towards the right. (00:39:20)
Continuity mistake: Poolside, Magnum asks Daniels "Why change now?" His notepad suddenly switches side going from the left hand to the right. (00:39:55)
Revealing mistake: During the flight towards Karen's location at the end of the episode, TC's chopper suddenly has emergency floats equipped on the skids in the shots when it flies over the coast. (00:43:00)
Deliberate mistake: During the episode, whenever daily newspapers are shown, they lack any indication of the date.
Other mistake: The clock in the millionaire's limo has all hands (including the second hand) perfectly still. (00:02:00)
Continuity mistake: Mr. MacLeish is in his plane, and before taking off he presses Play on the cassette player. He is holding it in a different way (fingers on opposite sides of the tape lid) between shots. (00:03:40)
Revealing mistake: When the plane is blowing dust all over the lawyer and the money-conscious nephew, you can see the face of the extra piloting the plane instead of Donnelly Rhodes. (00:03:50)
Visible crew/equipment: When in the opening credits the names of the special guest stars Donnelly Rhodes and Elaine Joyce appear, on the side of the Pitts Special you can see the reflection of the set lights. (00:03:50)
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)
Audio problem: The lawyer and Magnum join the others in the room for the reading (rather, play) of the will. One of the prospect heirs says "It's about time then", but their lips are not moving and the muffled and unnatural ambience makes it even further clear that it is dubbed in. (00:08:55)
