Revealing mistake: When Magnum shoots the nun, the one who falls off is a stuntman who would pass off as Gargamel but not as Christopher Morley. (00:46:25)
Revealing mistake: The killer nun is making "his" escape; shoots dead one secret service guy who in the spirit of 80s network television shows not a drop of blood and is propelled through the air as if he was hit by a cannonball and not some little silenced pistol. (00:45:25)
Other mistake: The priest and altar boys have the slowest reflexes ever; they stand as if nothing happened during the whole shootout, and can be seen finally covering behind the altar only after a few cuts, after the shots have already stopped. (00:45:05)
Continuity mistake: Magnum and Kate have the "I am mad at you" "And I'm mad at you!" exchange. When the camera angle changes, the sheets in front of Magnum slid past the edge of the table a bit. (00:36:55)
Audio problem: Kate answers the phone at the club saying "Hello?" without moving her mouth. (00:31:35)
Other mistake: The bicycle the killer uses is recognizable for its unique color pattern as the same prop used in the season 1 finale, when it was supposedly an expensive gift from Robin Masters, imported exclusively from Italy. (00:31:15)
Continuity mistake: Inside Rick's room with both him and Mac waiting, Magnum pours his drink from the decanter in his right hand, and then left hand. (00:28:55)
Continuity mistake: Magnum drops by at the hotel where he expect to find Kate and the Jororo delegation. As he pulls over in front of it, there are two elder ladies walking by, away from the hotel. One of them is wearing bright yellow pants and a very colourful top with horizontal stripes. Magnum gets into the hotel, and one of the extras he walks past right as he approaches the concierge, is that lady. And the other lady she was walking with, in a blue dress with white and red palms, is at the same desk. (00:21:45)
Continuity mistake: Kate Sullivan is interviewing the Prime Minister. Notice the position of the cane next to the end of the armrest at the beginning, and then when she is called to the phone; the cane is now at a different angle on the opposite end. (00:20:00)
Revealing mistake: Higgins is explaining the story of Bannister, which he conveniently happens to know all about. In Magnum's reaction shot, you can see that he starts giggling a moment before Higgins actually gets to the amusing part (that he was specialist at posing as a female). (00:17:50)
Continuity mistake: Magnum buys wine from Higgins using his potpourri of crumpled cash. He then walks past him dropping the casual line about MI6: from one shot to the next, his left hand moves from the neck of the bottle to the belly. (00:16:55)
Continuity mistake: In the scene with Mac and Rick fishing at the marina, continuity is all over the place as far as their hand movements is concerned; they move the fishing line with one hand that becomes the other in the next shot, several times. (00:13:00)
Continuity mistake: Magnum checks out of the photo Kate Sullivan gave him. First shot and close-up, he's looking at it holding it between his fingers, placed on the side. Next, he's holding it in one hand by the bottom. (00:10:50)
Continuity mistake: Under the threat of nerve gas, Magnum relinquishes the bottle of wine to Higgins. Higgins grabs it at a different height in the different shots (high, low, high). (00:06:00)
