Audio problem: The chopper is so noisy that people in it can barely talk to each other over the noise (as made clear abundant times in the series, including the previous episode when they "muted" Higgins switching off his intercom), but Thomas and TC are having a conversation while the helicopter is hovering meters above and Magnum is still with his feet in the parking lot. TC's lines are also neatly dubbed in. (00:39:00)
Continuity mistake: There's obvious recycled footage to pad the episode during the approach of the chopper to the "fishing spot"; they take off with a chopper with normal skids and no doors, but the one flying over the ocean has flotation pads and its doors in place. The pilot is also wearing beige flare pants and not TC's jeans. The same mistake happens when he flies Magnum over, same recycled footage. (00:35:45)
Continuity mistake: When Ed Kanfer's widow tells Taylor "But he's gone", her hands are not on his shoulders, where they appear in the next shot. (00:32:10)
Continuity mistake: Tailing Cam Chung with his Ferrari, Magnum does not have to go too far, seemingly, since he keeps meeting the same people over and over. A guy with a red T-shirt under a plaid shirt, a woman with a purple dress, one man with a blue tee and a single horizontal stripe, a man sporting a 'stache and wearing jeans and a pale blue Hawaiian shirt, etc. (00:21:00)
Continuity mistake: Taylor asks Magnum if anything happened to Linda. Magnum says "No!" twice; in the first shot his left arm is on top of the back of the couch, in the next one it's slumped into one of the pillows. (00:15:20)
Continuity mistake: Magnum meets his new client. He asks "Have we met somewhere?", with his fingertips touching. "We were briefed together once, at Da Nang" the client replies, while Magnum lowers his hands and puts them on his hips. New shot, and he is again in the previous position, with the fingers touching. Similarly, the client mistakenly has his arms crossed a couple Transitions later when he says the two teams never hooked up. (00:08:30)
Plot hole: With the murder happening literally on tape, it's quite extraordinary and inexplicable that the police did not acquire the footage as evidence, especially with film buff Lieutenant Tanaka investigating, who is not fooled by the culprit's act. The footage would have been used for insurance reasons as well, and instead it is reduced to some novelty everyone checks out just to fight boredom on an evening at the estate.
Continuity mistake: By the deathbed of her husband, Olivia Ross asks, startled by Magnum "What are you doing here?" Her right arm position changes (along the railing or not) depending on the camera angle. (00:45:35)
Continuity mistake: Searching the trailer, Magnum tells his friends the suicide theory. Rick in close-up is holding the flashlight in the same left hand he is leaning against the drawers with, but it is in his right hand at the cut. (00:38:50)
Other mistake: Olivia Ross crushes in anger the paper cup she was drinking coffee from - and she does not wet her hand or stain her perfect white dress doing so. (00:23:25)
Continuity mistake: Higgins introduces Lt. Tanaka with a hand gesture in close-up he showed no sign of doing in the previous shot - in fact he had that hand down, planted on the desk. (00:16:45)
Continuity mistake: The director, Myrt Callahan, is talking to the producer while Higgins is on the phone with Robin Masters. Knox says that people can grieve and work at the same time, and she has both arms forward, but in the background when the camera focus is on Higgins we see her right hand on her waist.
Continuity mistake: Magnum and Rick by the wall are looking at Jack Martin going back to his trailer. They are on a spot in the sun and have plenty rays on them, but in the rest of their exchange with a very bored TC they all are in the shadow. (00:13:00)
Continuity mistake: The lads greet Magnum growling at him. They pass by a table with a flower centerpiece on it. A minute later, the producer gives him the thumbs up as he walks out, saying "Welcome aboard"; the table gets back in frame, and now the flowers are gone and all there's left is a decorative plate. (00:05:15 - 00:06:55)
Continuity mistake: Inside the study, Higgins is having Zeus and Apollo bite the dog handler. In the background, William B. Knox stands behind the armchair with his right hand over the left. The hands have instantly traded places in the next shot. (00:04:40)
Continuity mistake: When Magnum tackles the 'commando' from behind coming off the wall, the elder guy with the white beret is holding both hands on the right armrest of the chair. New shot and he has just a hand on the other one. (00:03:25)
Revealing mistake: To board the helicopter as it takes off is a stunt double with a bulkier core than Tom Selleck's and lighter brown hair. (00:39:25)
Other mistake: Magnum lights up a signal fire for TC. It is supposed then to raise significant smoke (which Rick spots) in a short time, but when we see the fire, it's not generating visible smoke. Moreover, Magnum uses fuel to light it up, but they are supposedly out of gas and had to paddle for a long while before getting to the island, so it's odd that they'd suddenly have spare fuel for that predicament the day after. (00:38:45)
Revealing mistake: When the bad guys are in search of Magnum but have to get back to refill their tank, they are sitting in a helicopter on the ground, with the sky (where you can also spot a jet plane) totally unmoving. (00:23:50)
Factual error: Magnum shoots a flare gun at a helicopter, and that brings it down making the heli's engine sputter and slowly lose altitude. That's Hollywood nonsense, as a projectile of that kind wouldn't do that sort of damage. (00:41:00)
