Never Again... Never Again - S1-E7
Audio problem: When Magnum chases the boat that is taking off, he shouts something to Rick about the coast guard with Tom Selleck's lips not moving. (00:43:15)
Never Again... Never Again - S1-E7
Audio problem: During the close-up of the photo held by Rick, Magnum's voice saying "Her right arm" is dubbed in with a marked difference from the rest of the conversation (added in post - perhaps to specify which arm, or originally the wrong one was mentioned and they corrected the mistake, but the artifact is strikingly noticeable). (00:39:50)
Never Again... Never Again - S1-E7
Continuity mistake: When Magnum switches on the table lamp inside Dr. Bernard Kessler's study, the pencil is on the left side of the green blotter. In close-up it sits on the right of the pad. (00:34:25)
Never Again... Never Again - S1-E7
Revealing mistake: The day for night filming is particularly obvious at the entrance fence, and when the two mysterious guys try are kneeling outside of the house wondering how many people they have to deal with, with just 4 shots; you can see perfectly white clouds. It's even worse later in the episode when the Ferrari stops in front of the doctor's house; you can literally see the sun shine reflected by the car and the wet asphalt throughout the whole scene. (00:26:15)
Never Again... Never Again - S1-E7
Continuity mistake: When Magnum runs into Saul and Lena's home, the shadow of the hedge covers the whole steps. They stay inside less than a minute, and when Rick stands there wondering how's gonna break the news gently, the hedge shadow reaches barely half the width of the steps. (00:11:10)
Never Again... Never Again - S1-E7
Continuity mistake: Look when Magnum and Rick in front of the shirt shop begin to get out of the car. Before the cut, passersby enter in frame, and are gone in the next shot. (00:09:10)
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)
