Continuity mistake: Rick gets the odds from Magnum and then puts the car in reverse. His left hand is on the left part of the wheel, right hand at the cut. (00:07:25)
Continuity mistake: Magnum met the Prince 5 seconds earlier and already he has enough of him and says bye, about to drive off. Danny says "Hey", and at the cut the glove rolled from under the right to the left hand. (00:08:20)
Visible crew/equipment: When Magnum walks into the guesthouse and finds Danny inside drinking one of his beers, the white tape marks are visible on the middle couch cushion, where Magnum will be sitting in following shots. (00:13:10)
Continuity mistake: Magnum gets back to his pad and of course the kid everyone's looking for just crashed there. In the first shot, overhead, you can see that Magnum's coffee table features several magazines, and in the corner, at the same level, a bowl. Magnum fetches a can of beer and sits by Danny, but the magazines now are in a different line, with the bowl above them. (00:13:20 - 00:13:50)
Other mistake: When Magnum is watching the game on TV, it is also the game TC is watching, which makes sense. What makes less sense is that it is also the same game, same action, that was shown just 3 episodes earlier in 4-8, when Rick and Higgins called him as he was supposedly in the Tiger Stadium with an invite for the locker rooms after. (00:17:35 - 00:34:40)
Revealing mistake: The prince and TC's protege have a fight when the spoiled kid is eliminated. They are supposed to be angry and serious, and the teammates too have worried faces, but in the shot when TC tells him that he's out of the game, against any logic the young actors are caught laughing. (00:23:20)
Character mistake: The coach of the Jororo team makes a joke about being cut by the king "Like Robespierre did to Louis XV in '89." That would have been Louis XVI (and not in "89" but (17) 93, although the year of the French Revolution is correct). (00:25:10)
Continuity mistake: Magnum comes back to the beach after some surf ski, where the prince struck a 'deal' with Ed Russler. Magnum's shirt is wet in two completely, and that's not a understatement, COMPLETELY different ways before and after John Saxon approaches. (00:28:30)
Other mistake: In the shots from inside the van it's easy to tell that Benny throws the newspapers in such a weak way that they hardly can reach past the outer fencing and walls - in fact the last one he throws before TC tells him "Not like that" is shown in the next shot landing on somebody's lawn, but from the van window you could see he tossed it into a driveway, at a height that could never go past the hedge. (00:32:00)
Visible crew/equipment: While TC is driving the van helping Benny deliver the newspapers, the hidden mic taped to Benny's chest, under his shirt, can be seen in a few shots from the van's passenger window, during this scene. (00:32:30)
Continuity mistake: During the paperboy run, TC stops the van and asks Benny a question. Benny was holding the paper vertically, but his arm is down in the next shot, and up again next, and so on. (00:32:40)
Continuity mistake: When TC asks Benny (of course with no foreshadowing at all) "You don't wanna be someone else, do ya?" his van is parked in front of a hedge. Cut, and they are in front of garage doors. (00:32:45)
Other mistake: Forgetting the absurdity of a kid who's never been on a horse before that can just hop on one and gallop all night long, the stuntman riding Agatha's horse when Higgins and Magnum watch them fade into the night wears a striped shirt; Benny in the morning is still on the horse, on the run, but has a sports jersey with a very different color pattern, basically bi-color with the full bottom half powder blue. (00:36:50 - 00:38:15)
Visible crew/equipment: Inside Benny's glasses when he is taken back to the Estate is the reflection of the set light screen. (00:39:10)
Continuity mistake: John Saxon hands Prince Danny's pic to the arcade manager holding it by the top left corner in close-up, but his fingers were on the top right in the wider angle. (00:41:20)
Visible crew/equipment: By the car exit of the Mokihana, both in coach Lum's car and in the Ferrari you can see the reflection of people standing by to film the scene. (00:44:10)
Continuity mistake: Rick tells (and shows!) Magnum that he's writing "a recipe for Veal Marsala for my mother back in Chicago." But the key plot element of 4-4 "Distant Relative" was that Rick raised his sister by himself, because Chicago was "a tough town to grow up in without any parents."
The Case of the Red-Faced Thespian - S4-E12
Other mistake: In the opening credits, the title of the episode appears without hyphen. (00:01:35)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Higgins mentions Robin's project to finance "a home for incorrigible boys." He already has in hand the two bombs he reaches for in the bag during the next shot. (00:03:10)
The Case of the Red-Faced Thespian - S4-E12
Continuity mistake: Trying to exterminate the mongooses with extreme prejudice, Higgins lights up the bombs twice in two separate shots. (00:03:35)
