Continuity mistake: Magnum puffs holding Keone's photo with his right hand - which was both hands before the sudden cut. He then drops the photo on the table, but when he digs the map from underneath the pad, the photo changes position entirely again during a sudden cut. (00:29:30)
Continuity mistake: Higgins wants to show Magnum the rare Kudu buck in a book. Picking it up from the shelf, causes 3 other books to lean forward. In the close-up that follows, just one book is misplaced. (00:26:30)
Continuity mistake: When Marion asks "He's dead, isn't he?" hair pops in front of her shoulder suddenly after the cut. In fact, throughout the whole scene notice how in close-ups it's in front of her shoulder, in wider ones behind her back. (00:24:25)
Continuity mistake: Magnum is saved, and it's time for the others to concern themselves with the assailant. Rick dives in a close-up to look for him. The mask is really close to him all of a sudden, and in a different position (practically touching Magnum's chest) in next shot. (00:23:20)
Continuity mistake: On his way to Rick's boat, Magnum stops to talk with the witch lady. A very short drive and he's then in front of the boat. Rick is in the background and he starts moving and preparing to greet him, but in the close-up it's as if he has been chilling all along and only then decides to be active. (00:21:20)
Continuity mistake: Marion Hammond unlocks the boat door and finds a mess. Between the establishing shot of the interior and the one with Tom Selleck inside, the towel on the ladder moved, and a diary tossed on top of the typewriter flipped without anyone coming anywhere near. (00:10:05)
Continuity mistake: At the beginning of the episode, the titular character makes his way towards the club. He glances at the Ferrari parked there, its nose towards the club. A couple minutes later, Magnum drags him out of the club (no valets involved), and the Ferrari now is parked facing the opposite direction and with a total change of natural lights. (00:03:10 - 00:05:20)
Continuity mistake: When the three henchman are knocked out by Billy on the chopper, they land in distinct positions (the two rightmost ones are facing right), that change when Billy gets out of the helicopter. (00:42:40)
Continuity mistake: The prostitute looks at Magnum trashing the nunchaku guy hiding behind the corner. Her hand is above the leaves of the potted plant, then under it in the last shot. (00:25:25)
Continuity mistake: Billy Joe "smooths things out" with the non-hooker and Magnum gets slapped in return. The cocktail umbrella on the counter goes from straight to folded between shots. (00:21:30)
Continuity mistake: Outside the King Kamehameha Club, Magnum knocks down Billy Joe Bob with a punch, and knocks away his cowboy hat too. The hat is flat on the ground when he is getting up, but was toppled over under the different camera angle. (00:05:45)
Continuity mistake: In pure movie fashion, a runner is chased by a big Sedan and she keeps on the road instead of swerving to the side and hide behind the many trees and posts. She does change lane at one point, though; when she does that, notice that in the closer view she is passing by a tree that is not next to a lamp post like in the wider angle. (00:02:15)
Continuity mistake: In the POV shot, when the car rams the jogger it sends a trash bin flying across, which is completely absent during the side view of the stuntwoman being tossed in the water. (00:02:20)
