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)
Revealing mistake: Billy Joe Bob steals the Ferrari, but the interior shot of the car with him switching gears is stock footage; the person in it has sneakers on like Magnum, not James Whitmore Jr.'s cowboy boots. (00:37:00)
Other mistake: When Magnum sprints to the ocean at the end of the episode, his bare feet are remarkably clean for someone who has just run through a lawn freshly fertilized, with Higgins just shoveling it in his path. (00:47:40)
Audio problem: Billy Joe manages to get through the not quite solid defenses of Ito. He shoos the geisha inside Ito's chambers and tels her "Go for a little while", with the actor's lips not moving at all except for "go." (00:43:35)
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)
Revealing mistake: When Billy Joe Bob downs the 3 Japanese goons hitting them with the skid of the chopper, only two (at most) are hit and on the chest, the other (again, at most) gets the impact of the other two knocked against him, and all of them land on soft grass. Yet of course they are unconscious and KTFO for good. (00:43:30)
Revealing mistake: Magnum is back from his meeting with Ito. When TC from his seat reaches for the heli door, you can spot he's someone else wearing a ski mask. (00:33:45)
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)
Character mistake: Magnum and Billy Joe Bob face one of Ito's goons. The guy is supposed to be competent with nunchakus, but he simply waves it around with no skill and in the close-up of his warrior yell, he strikes a pose with it but you can see at the bottom of the frame he misses the catch and does not grab the other stick. Obviously the extra was hired simply because of the looks and ethnicity but had never used this goon's supposed weapon of choice before. (00:24:55)
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)
Revealing mistake: The chopper lands and an upset Billy Joe Bob disembarks. A low standard for body doubles is set when you realise that TC has been replaced by some white dude wearing a bandit scarf on his face and sunglasses. (00:15:00)
Revealing mistake: During the kendo sparring, on the breastplate of the kendogu you can see the reflection of the set lights, practically all the time. (00:11:00)
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)
Audio problem: Billy Joe Bob's "He got in my way" response to Rick who tells him to leave the club after busting Harland's jaw is noticeably inserted in post, rather poorly dubbed in with a change of levels and discontinuity in background sound. (00:04:50)
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)
Revealing mistake: When the guy tricked by Magnum gets out of the car, check out of the very right side of the frame. You can actually see the hand of one crew member releasing the garage jack's lock, so that, when the car is kicked, the relatively light impact is enough to release the hydraulic lift and make the car comically bounce back on the ground. (00:15:25)
Revealing mistake: Magnum manages to shake off the 'government guy' by putting his car on a jack while Babs provides a distraction. But if you check the moment when the guy gets on the car, the back wheels are in frame and not at all off the ground as the clever ruse needs them to be. (00:14:40)
Continuity mistake: When Rick is helping Magnum after the swim session, he's putting the sock on him twice (although he did not finish the first) and the shoes on the ground are in radically different positions between shots. (00:39:45)
Continuity mistake: When Magnum protests that TC is "killing him" with his too much vigorous toweling, TC is wearing his baseball hat backwards, while it's worn normally in the previous and following shot. (00:39:20)
