Did You See the Sun Rise? - S3-E1
Revealing mistake: TC's arrival is announced by the loud sound of his helicopter, which makes Higgins' desk comically shake. Fun sight gag, but looks totally phony, since everything in the room, including the plants, is completely still. (00:09:00)
Past Tense - S3-E4
Revealing mistake: TC kicks the boss villain in the face as he tries to climb back the hill; the kick misses by a mile. (00:24:00)
Revealing mistake: When Agatha and the other "ladies of the Sandwich Island Botanical Society" show up near the chopper, aside from TC's perfect reaction toward Higgie Baby, in this shot (and a following shot) the wood box and wedges are visible under the chopper, as they are there to be the stable step up for Agatha, when she enters the chopper from the other side. (00:45:00)
Revealing mistake: When Carol and Magnum jump from the terrace, you can see her land way too close to the edge of the garbage truck container; the stuntwoman's foot hits it in fact, and one of her shoes ricochets in the air. The stuntwoman picked up an injury, obviously, but Carol is unscathed and complains just about the suit getting dirty - when at the very least she lost one shoe. (00:25:30)
Revealing mistake: After wiring TC's chopper, Billy Joe Bob puts the headset on and looks behind him. When he turns his head to look, you can see that on the right pad there's something handwritten with an ink marker on it; "D. JONES." Makes no sense on TC's chopper, but much more sense when you know that the aerial coordinator and helicopter pilot for this season of the show is named in fact J. David Jones. (00:40:45)
Revealing mistake: All the 'boxing' in the episode is unrealistic pure 80s Hollywood hot camp garbage, but the finishing blow of the final match in particular is miles off, bad even for the low standards of that sort of 'action'. (00:44:10)
Revealing mistake: The shot of the Ferrari during the directorial credits (filmed from a car in front) does not feature Roger E. Mosley behind the wheel; you can see a bit of longer hair sticking from the top. (00:04:30)
Revealing mistake: TC's accident with the hog pen is shot in (at least) two takes, one with the stuntman dodging the car inside an otherwise empty pen, and the establishing shot with the animals when the car is still not so close - and then when the car has stopped at the end and there's no danger for the pigs. (00:04:40)
Squeeze Play - S4-E7
Revealing mistake: Higgins speaks with the idiotic nephew of the most hated (temporary) new boss, who tells him uncle is in the Den. Higgins opens the door and before it cuts to the new scene, you can peek through the door and see that the lights are switched off; Higgins is walking into an empty room (would be fun if it were the broom closet, but it's actually the correct photoset, just with nobody there). (00:19:25)
Squeeze Play - S4-E7
Revealing mistake: The construction workers in the bar believe Magnum's bluff about being an inspector, and make a run for it trampling him. Tom Selleck's stuntman is the one taking the risk of having a mob of big guys stomp him - and you can actually spot a fake moustache dangling loose during the action. (00:18:30)
Squeeze Play - S4-E7
Revealing mistake: When Lola hits back Rick's pitch and gets him in the 'nads, it's transparent in the shot of her swing that the ball was not flying back at the pitcher in a million years. (00:10:55)
Revealing mistake: As everyone marches towards the happy ending of the episode, the Higgins lookalike that walks by Magnum at the airport looks in fact nothing like Higgins. (00:41:50)
Two Birds of a Feather - S3-E19
Revealing mistake: The plane is supposed to be completely out of fuel and simply gliding when it passes over Magnum's head, but you can see its propeller is spinning. (00:09:15)
The Curse of the King Kamehameha Club - S1-E11
Revealing mistake: Rick is leaving the club, or at least the kitchen. In Larry Manetti's close-up, the background shows various detergents with the label flipped in a mirrored shot. (00:15:45)
Suggested correction: This is not a mirrored shot. The brand name "Ajax" (all lowercase letters as "ajax") on all three of the cleansers is not backwards; neither is the Pan Dandy soap jug in the sink. And the scars on Larry Manetti's face are in their proper places.
