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. (00:02:00)
Plot hole: Towards the beginning of the episode a peculiar arrangement is presented; Magnum has to share the guest house with two stewardesses, Mandy and Suzie. The night of the party, they both go for a swim. Mandy is involved in a shooting, and following scenes include her resting at the guest house. Suzie is never heard from since. She does not have a place to sleep; it is made clear that the main house has not been arranged yet for that purpose, the Brigadier and his escort have to leave first. She is not there in the morning. She just vanishes.
Other mistake: The photographer takes shots of the Brigadier on the balcony. The Brigadier is wearing a shirt and pants, fairly casual as expected. When Hooker is left alone in the dark room of the terrorist, he is looking at pictures of the Brigadier wearing a white jacket and bowtie, which is the outfit he will wear at the party several hours later. (00:12:30 - 00:25:35)
Other mistake: The creepy photographer guy is taking pictures throughout the episode. His camera somehow reaches everywhere on the estate; front gates, lawn, the Brigadier's balcony, with extreme close-ups and disregard to walls and structures in the way. It's one of those magic movie cameras.
Other mistake: The IRA operative puts the bomb into the Audi with a timer rigged for 5:00. Three minutes and a half of time that cannot be compressed (no cuts to any other scene that happens simultaneously - and if anything, more time than that should have realistically elapsed) pass before Magnum even gets on the Ferrari and drives out of the Nest. The way it is shown in the episode, Magnum could never make the heroic save. It gets even worse at the ending; 15 seconds remain on the timer and Magnum has yet to force the Audi down the beach road, the car has to reach the end of said road, Magnum runs, on foot, to their point, convinces them that there is indeed a bomb, and they run for cover.taking cover and waiting for the thing to explode! A minute could have been spent for that task alone. (00:39:20 - 00:42:50)
Factual error: The villain holds Magnum at gunpoint with a weapon with a silencer. Which is useless, the gun being a revolver. (00:41:20)
Factual error: Richard Johnson appears in the end credits as "Brigadier General Alistair Ffolkes, Royal Army", and is consistently referred to that way by Higgins and Hooker. The rank was abolished in 1921, the Royal Army would have him as as a Brigadier or a higher rank.
Other mistake: Magnum is taunting the dobermanns while he's grabbed and pushed against the door by two dudes. They are big, and armed. The room is normally lit. There is just no way he could get inside and somehow Miss their presence. Especially the one coming at him from his right; there is a railing on that side of the landing. Magnum would have literally bumped into him; it's not that because he was out of frame he was not existing. (00:05:15)
Other mistake: When the lads chase Magnum at the beginning, first of all they take a disproportionate amount of time to reach him, and secondly, the same footage is reused, so they effectively sprint past the same tree (with the same 2 dead leaves and straw by it) twice. (00:04:40 - 00:05:05)
