Continuity mistake: When Mandy is leaning against the Audi chatting with Higgins, her towel changes position (its end pops in front of her arm, or is tucked underneath). (00:39:35)
Deliberate mistake: In the scene that sets up the climax involving the car, both the trunk and the gas cap are unlocked to make the filming smooth. (00:38:50)
Continuity mistake: When Magnum tells the Brigadier "I don't believe you have a...", the Brit's shoulder is casting a shadow on his chest. Neither of them moves, but when Magnum is back being in frame from the waist up, Richard Johnson's shadow has moved significantly off. (00:31:55)
Continuity mistake: The Brigadier gets up after drink and cigars; on the couch, Mandy is sitting with her right leg crossed over the left. The camera cuts closer to her and her colleague Suzie, and she is now sitting with the left crossed over the right. (00:28:10)
Continuity mistake: Inside the suspect's house, Magnum holds in close-up the instruction manual of the Audi and a receipt. Holds the receipt by the side, but when he puts them back in the drawer, he is holding the same paper by the top. (00:22:50)
Continuity mistake: Magnum sits on the couch and tells Mandy that his life is not "that exciting." Selleck's arm is on the back of the couch, Robin Dearden's isn't, until the angle changes, and then both have their elbows sticking out. (00:18:35)
Continuity mistake: Magnum leaves the hanger and the bag in Rick's hands as he tries the jacket on. Rick asks "What is this, the tailor shop?" with the hanger in the left and the bag in the right, but they switch in the next shot. (00:13:15)
Continuity mistake: Higgins gives Magnum back the envelope with the incriminating photos. Magnum puts it under his arm; the envelope sticks under the flap of the breast pocket. Change of view, and the envelope is covering it. (00:11:45)
Continuity mistake: When Magnum is talking with Mandy at the tidal pool once the other girl left them alone, the towel in her hand changes position quite noticeably - it shows a lot more of the yellow-brown pattern in the close-ups, and blue in the first and last angle. (00:10:00)
Visible crew/equipment: Towards the end of his phone convo with Rick, Magnum peeks through the window. As he is sitting back on the bed, on the curtains you can see the shadow of the boom mike going down and then up again. (00:08:50)
Continuity mistake: One of the guests sounds eager to know more about Magnum's exciting line of work. Mandy has towels in her arms, and she holds them in a different way (left hand above the opposite wrist, or below the elbow) depending on the camera angle. (00:07:00)
Continuity mistake: Magnum reaches the bottom of the stairs of 'his' quarters and makes a bitter comment about Robin's taste in guests. In the shot with just the two girls, the one with the jacket is glancing with her arms folded; they were relaxed down her sides before the cut. (00:06:30)
Continuity mistake: Two dudes bend Magnum over the railing the moment he gets inside the guest house. His arm is restrained behind his back at first, then all of a sudden his arm is in front of the railing, but it's bent behind his back as it gets back to the overhead angle from before. (00:05:20)
Continuity mistake: Magnum says "Hi guys!" to Zeus and Apollo through the door; the blue fabric of his duffel bag shows through the hole, but when he gets grabbed and frisked from behind, the bag is away from the door's hole. (00:05:10)
Continuity mistake: When the lads arrive by the door, the mail slot is shut in blatant disregard to close-up of Selleck's face grinning through it. (00:05:00)
Continuity mistake: Magnum tosses his bag over the wall. The bag bounces off a tree and falls vertically next to it, but when Magnum climbs the wall, the bag is by his landing point, not by the tree. (00:04:00)
Audio problem: The episode opens with a news report, which itself opens with the words; "In Belfast, Northern Ireland, where a bomb blast destroyed an office building last Tuesday, a special task force under the command of Brigadier General Alistair Folkes", etc. The report runs for a minute, then the phone rings and Higgins, off-camera, answers. The audio of the TV fades in and out to leave room to the relevant conversation, but you can still hear that it's going in a loop, repeating the exact sentence it started with and moving on from there word by word.

Continuity mistake: The bad guy is supposed to retrieve the painting just a few minutes after Magnum made the drop, but the light is very much different between the two scenes, and the sky seems to change even between the moment the obese villain goes up the stairs and the time he somehow makes his way down them without dying.

Continuity mistake: On one side of the metal detectors, the bad guy has sweat soaking his shirt from shoulders to pits. When he retrieves the painting, he has just a stain at the middle of his back. (00:46:00)

Revealing mistake: Rick is lurking in the pool; once the evil greenshirt Orson Welles-lookalike is hopping down the stairs, the cement in front of his hiding place has a big wet spot, no doubt from previous takes when the actor had to come out of the water dripping all over the deck. (00:41:00)
