Continuity mistake: Magnum in the first chase scene passes a device with "cool lights" to the kid in the back seat, but he's not calmed down by it. The car and the pursuing vehicle leap down a hill, and you can see the trunk of the car is a total mess, bulging wildly on the right side. However, it's fine in the rest of the chase. (00:03:05)
Continuity mistake: After the North Korean 'flashback' comes to a screeching halt, behind TC you can see that Rick is grabbing a beer that someone hands him. But who? Nuzo, of course...who is behind Thomas in the next shot, so on the opposite end of the room, and only after another cut walks across to give Rick that beer. (00:03:55)
Continuity mistake: The first time we see Higgins, she is holding shock collars, but they keep switching hand throughout the scene. (00:06:00)
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: 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: Magnum tries to dial the number found on the notepad. In the background behind the wrecked Ferrari there are 3 people. A policeman is walking towards them. Magnum waves the phone with disappointment during a cut, and the policeman instantly teleported meters forward and has joined the 3 other dudes. (00:14:25)
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: 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: 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)
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: 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)
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: Rick pulls up in a car to the right side of a helicopter, gets out, and gets in the helicopter. When the helicopter is shown taking off, there is no car next to it. (00:38:20)
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: 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: 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 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: 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: 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)
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)
