Continuity mistake: TC tells Magnum "bet you could do it" when Magnum puts down his beer. Next shot and Magnum's hand is suddenly around the beer bottle again. (00:03:05)

Factual error: Magnum takes part to an Ironman triathlon contest, but the writers did not bother to follow the correct order of the parts of the race, which would be swim, bike, and then run. Here he cycles last.

Continuity mistake: Magnum is stretching after his morning jog in front of a bottle of Coops that turns between shots. (00:02:35)
14th May 2020
Magnum, P.I. (1980)
Factual error: Magnum is scouting the prison facility with his binoculars. During the scene, the audio track to give the impression of the jungle surround has the trademark kookaburra laughter, which is not a Hawaiian bird. (00:33:55)

Magnum, P.I. (1980)
Continuity mistake: The titular brunette easily overtakes Magnum during his jog. The sweat patch on his shirt becomes much larger through the span of a brief cutaway, and when he joins Rick after the jog, his shirt is completely dry. (00:03:10)

Visible crew/equipment: During the fake accident, in the semi-POV shoot with the camera behind the wheel, you can spot roadside the film unit (crew and equipment) that filmed the previous shot, with the car cutting the bike's path. (00:27:00)

Magnum, P.I. (1980)
Continuity mistake: When Higgins starts yapping about the fascinating case of the homosexual corporals in Wales, Magnum sighs with an arm over the couch's back, changing from the earlier pose between cuts. (00:48:20)
14th May 2020
Magnum, P.I. (1980)
Continuity mistake: At the end of the episode, Joy is laughing when Higgins mentions the various bands; her position on the couch changes rather obviously between shots. (00:48:00)
14th May 2020
Magnum, P.I. (1980)
Audio problem: Magnum screams "SHUT UP!" to Higgins, but actually when John Hillerman is on his back during the mountain climb and mentions Lord Mountbatten, his lips are not moving. (00:38:40)
14th May 2020
Magnum, P.I. (1980)
Revealing mistake: Magnum is carrying up the mountain stairway a Higgins-shaped dummy instead of the real John Hillerman, as obvious by the lifeless bounce of its legs. (00:38:20)

Magnum, P.I. (1980)
Stupidity: The good fellas at Laseronics have a CCTV camera Joy and Magnum get past, which somehow detects her sneezing from the other end of a huge hall with active machinery. The camera does not detect the sound in Higgins' cell, and they don't give a damn about the fact that the camera has not been broadcasting anything since someone threw a towel on it. Strangest security system ever. (00:37:15)

Continuity mistake: The bike falls down diagonal to the road lines, but it's practically parallel in the rest of the scene. (00:27:00)

Magnum, P.I. (1980)
Continuity mistake: Rick's hand with the remote turns at every cut when he makes the password joke on a depressed Higgins. (00:26:20)
14th May 2020
Magnum, P.I. (1980)
Continuity mistake: When Magnum does his puking act to make his best friend lose a lucrative job, the lady's hair is in front of her shoulder hen the camera is in front of her, windblown away from it when the camera is behind. (00:21:10)

Magnum, P.I. (1980)
Other mistake: Contrarily to what TC says, the alarm is not 'covered with corrosion', in fact it looks pristine. (00:16:55)
14th May 2020
Magnum, P.I. (1980)
Revealing mistake: Rene cleverly avoids the trap; he turns the wheel to the left, but the car swerves to the right. (00:02:10)

Magnum, P.I. (1980)
Factual error: Just before the fade-out of the first shot of Robin's limo in France, there are 3 street signs saying "Meyrargues 5 kms", "Marseilles 22 kms", "Aix-en-Provence 6 kms." It's an impossible triangulation; they are almost on a line, Marseilles is about 40 kms south of Aix, which is about 18 kms south of Meyrargues. (00:01:40)

Magnum, P.I. (1980)
Continuity mistake: The valet brings the Ferrari in front of the club. Digger leans on it with her right hand, dollars in her left hand, but in the next shot the money is on the same hand she is leaning on. (00:07:00)
14th May 2020
Magnum, P.I. (1980)
Continuity mistake: At the club, Rick teases Magnum about not being able to break the ice with Joy Doyle. He has his hand on the fruit juice glass, off it, and on it again. (00:05:05)

Magnum, P.I. (1980)
Plot hole: After the farcical scene with Rick and TC playing Asian goons, Magnum says in his trademark voiceover; "I know what you're thinking. After the phony beach attack, I should have said goodbye", etc. But the staged attack was in a back alley, in the streets. There are a couple of deleted scenes that pop by in the teaser and never made it to the actual episode, plus an actual beach attack happening later, so it's hard to say what Magnum was referring to, but in the episode as shown, makes no sense.
