Continuity mistake: When Wanda Martine, Princess of Turbia has a giggling fit at the expense of Candice Wingate's dead husband, she holds no glass, but was holding one in the previous shot. (00:24:40)
Continuity mistake: When Prince Roland calls the bandit "Impressive, but foolish", his wife's hand is on the table holding a cocktail umbrella all of a sudden at the cut. Later in the same scene her other hand holding a glass peeks in view showing she is drinking, but in an intermediate shot she is actually pouring the drink in another glass, moving the hand in another direction. (00:23:20)
Continuity mistake: The wine stain on Higgins' chest changes shape and size throughout the episode; in particular you can notice from the wine cellar to the sequence upstairs when Magnum spills the drink the stain gets longer and thicker on the button line. (00:18:30 - 00:19:10)
Continuity mistake: The criminal at first has his shirt wet in the shoulders area and down his collar and buttoned center. In the wine cellar scene, the center is dry, and returns wet when they return in the dining room after shooting Higgins' radio (and Robin's immature wine). (00:16:00)
Continuity mistake: Magnum in his fangirly reaction to the Tigers' ace player is barely able to point him towards the dining room. In the shot from behind he at least brings the umbrella back in its original position, but it's still across his chest and in front of the opposite shoulder in the front view. (00:10:00)
Continuity mistake: Duke Davis hands Magnum his umbrella, hook of the handle facing his left. It faces his right in the close-up of an ecstatic Magnum. (00:09:25)
