Continuity mistake: Magnum and Higgins are tailing the terrorist in the big red tallywacker. In the little intermission with the fish smell gag, Perdita Weeks is not wearing her seatbelt, while she does previously and after. The belt goes on and off also when they are found out. (00:34:00)
Continuity mistake: When the staff sings Happy Birthday to Magnum, Higgins joins in. Both Magnum and Juliett touch their own face with lack of continuity from one shot to the next (her hand is under her chin or not, his hand is suddenly at the side of their head, etc). Likewise when the maitre tells Magnum that they will bring the cake into the kitchen, a man behind Magnum claps right over his shoulder, only for his hands to be gone in the next shot. (00:32:35)
Continuity mistake: At the restaurant, Higgins tells Magnum that his client served in the Vietnam war. When she says that, Magnum has just put down his fork, but in the next shot, when he looks at her surprised, the fork is back in his hand all of a sudden. (00:31:50)
Continuity mistake: During the conversation with Magnum about going to dinner to investigate, in particular after her refusal, the bottle of glue stays firmly in Higgins' hand during the close-ups, but when it cuts to wider shots it pops at distance on the table. (00:27:00)
Continuity mistake: When Higgins asks Magnum if he just asked her out on a date, she is initially dealing with her vessel with both hands, but at the cut she is using just her right hand. (00:26:00)
Other mistake: When Magnum asks Higgins a favour, she tells him that he already asked for one 'last week'. She repeats that later in the terrorist's car. With that being a reference to the previous episode, it means that her arm, literally pierced by a bullet and that she had in a sling, healed completely without as little as a bandage (she is even wearing a sleeveless dress!) in 7 days or so. (00:25:40)
Continuity mistake: Magnum and Rick find the fish abandoned in the middle of the road. In the first POV shot camming towards the fish, there's a bed of ice cubes all around the big tuna. In the close-up the ice cubes are scattered leaving a sizeable portion of asphalt visible. (00:21:35)
Continuity mistake: Magnum tastes Kamekona's sauce and says "That's not bad." The big guy lets go of the wooden spoon, but in the next shot he's holding it again. (00:12:15)
Continuity mistake: Thomas holds the picture of the 300-pound tuna when he sees it for the first time in a different way between shots - fingers on the corner, fingers just on the side. (00:07:15)
Continuity mistake: Magnum asks Higgins to take a left turn. When he adds "Please?", Perdita Weeks' hand is in frame, placed against her temple. In the shots before and after it is on the car door. (00:01:40)
Continuity mistake: When Magnum and Higgins are having the chat about MI6, Magnum's hair changes (random wisps appear and disappear) between shots repeatedly. (00:36:25)
Continuity mistake: When Magnum and Higgins have the exchange with "THE worst apology", Juliett is rolling her shirt back over the injured part twice in the two separate shots. (00:36:10)
Factual error: Magnum comes up from the boat with 1 kg of gold - as also inscribed on the bar itself. Thing is, the ingot he brings is massive; a kilobar, even of the brick-shaped kind, is never as large. (00:34:15)
Continuity mistake: When Kim says "coordinates" there is nothing on the counter besides the open styrofoam box that has been there throughout the whole scene. In Magnum's reaction shot suddenly there's take-away food on the counter. And when he says "Windward side", the paper note has rotated all of a sudden in his hand. (00:29:45)
Continuity mistake: Lara is telling Higgins about Magnum getting almost married. She is holding her cup in hand, the rim pokes in frame. When Higgins' phone rings and she picks up Magnum's call, Lara has to reach for the cup and only then puts it back into view. (00:21:50)
Continuity mistake: Magnum visits Captain Buck Greene. Out of the whole lengthy scene, when he tells him "He was kidnapped and murdered", and 40 seconds later "because you have a problem with me", he has a wisp of hair on his forehead. All the other many shots show him with a forehead clear of any hair. (00:19:00)
Continuity mistake: Thomas receives Nuzo's phone call and reaches for the watch and ring. The watch shows the time; 8:35. Later when he shoots Nuzo's kidnappers the same watch shows it's 2:40. He went straight to his friend's house, not 6 hours later. (00:10:45 - 00:12:00)
Continuity mistake: Zeus and Apollo are fighting over a towel. Magnum calls their attention and they begin to chase him. One dog, closer to Magnum, starts running right away, the other lags behind to chew on the towel and take it with him. Next shot the dog with the towel is the first one to run after Magnum. (00:10:15)
Continuity mistake: When Magnum steps away from Kim's kiosk without paying, he has two pieces of meat on the skewer, which become just one in the next shot. (00:39:00)
Continuity mistake: Thomas is talking with former codebreaker Kim Kil-Yon. Kim says the numbers could be "social security", and as he says it he puts a take-away box on the counter, using just his right hand. At the cut he is handing the box over with both hands. (00:29:40)
