Never Again... Never Again - S1-E7
Continuity mistake: Rick and Magnum see an ambulance in front of Saul's home. There's a guy walking down the street, exactly on a curb cut. The Ferrari races by him, and yet in the next shot the guy with his relaxed stroll is several meters forward. (00:10:35)
Never Again... Never Again - S1-E7
Continuity mistake: In the close-up where Rick giggles at Magnum after he got smacked, his pen is in his left hand. Next shot and he's writing with his right hand. (00:06:05)
Never Again... Never Again - S1-E7
Continuity mistake: In the first scene with Saul Greenberg outside his store, the same woman with blonde hair and a yellow top and blue pants passes behind him at least three times. (00:04:00)
Never Again... Never Again - S1-E7
Continuity mistake: When the Mercedes gets close to the shop (as the two occupants themselves say), it cuts to a closer angle, but the passersby change during this cut (the woman with a purple dress jumps 15 meters ahead, the people past the carpet store are different, etc). (00:03:30)
Factual error: For the ballistic test, Higgins goes on to explain in great length that the shell contains 12 pellets, but when he displays the effect on the second target, it's blatant that there are way more than 12 holes in it - and the way the test is done, it is specified that it is the result of a single shell being fired. Incidentally, there are also more pellets than what Higgins states when he empties the shell initially -14 instead of 12 - but this last detail realistically can be assessed only if you pause. (00:29:20)
Revealing mistake: The prosthetics for Magnum's war wound at the collarbone are off during the volley scene at the end, so it just looks like Tom Selleck has a worn-out patch sticking from his chest and about to come off. (00:48:20)
Continuity mistake: Rick leads Magnum to David Norman that is drinking heavily at the club. When he shouts "Nurse" at the beginning, a woman in a pink bikini holding a straw hat moves across the area to get to railing. That same woman walks in and "just reaches the railing" about 4 times during the remainder of the scene. (00:10:10)
China Doll - S1-E3
Revealing mistake: When Higgins tells Magnum that he has to get into the safe first, Tom Selleck turns around and does a cheeky eyebrow-wiggle thing so well executed that will stay as the end shot for the opening of the whole series. A minute later, Higgins commands the lads to kill (!), and the turn and waggle are shown back in an obvious mirror shot. (00:47:45 - 00:48:40)
Revealing mistake: There's a neat and funny transition between the moment Rick tosses in the bin the orange juice bill that he knows Magnum will never pay, and a sponge being thrown into a bucket as Higgins polishes Robin Masters' Audi. The sponge though comes in from the right, way off Higgins' position. It's not John Hillerman that tossed it, but some stagehand. (00:16:40)
Continuity mistake: When Magnum works on picking the lock to his own home, the plant next to the door is the characteristic Swiss cheese plant; it has 'holes' in the leaves. The dogs arrive and scratch at the door, and the plant is now a different one. The table and chair appear also to have moved - probably it's footage from a totally different moment or location. (00:05:00)
Continuity mistake: As he does his Hooker bargain, Magnum takes a sip of beer, held in his right hand. Hooker agrees saying "All right, all right" and the bottle is popping in frame from the left. (00:15:45)
Continuity mistake: Magnum jumps in the Ferrari to stop the bomb. He is wearing his blue Lacoste and beige pants. The car sprints out of the gates...and Magnum lost his pants. But it's nothing compared to the interior shot of the Ferrari that follows; he's wearing now blue jeans, and shifting gears wearing his team ring on that hand - but it was on the left hand earlier. (00:42:50)
Continuity mistake: Rick smacks the cork on top of the wine bottle after he poured for Magnum and himself. In the next shot of the table following TC's messy arrival, the cork is almost all out. (00:46:25)
Visible crew/equipment: When Rick serves special Sarduci-style sauce and wine to Magnum, set lights are reflected in Tom Selleck's shades. (00:46:10)
Continuity mistake: Magnum approaches the Audi in a spot where the road is straight in longshot, but in the perspective with the camera just in front of Higgins, they are coming off a curve. (00:44:20)
