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)
