Continuity mistake: Magnum is going to deliver the blackmail money. As he gets out of the car in the aerial longshot, he has dark shoes, as opposed to the white trainers he sports during the episode. (00:13:20)
Continuity mistake: In the climax of the episode, Magnum forces Amy to look away using the left hand, then the right hand. (00:42:00)
Continuity mistake: When Rick tosses the disgusting burger mess on the table inviting Higgins to "have some lunch", in the reaction shot on John Hillerman someone from out of frame puts down a bottle of Coops that is quite literally full to the brim. Next we see Rick laughing, but his bottle is half empty. (00:27:15)
Continuity mistake: When TC says "This ain't no lunch", his right hand jumps on the table, when it was off it when he dropped the burger in its box. (00:25:15)
Continuity mistake: Inside Frank La Rue's apartment, Magnum approaches his suitcase. The position of the suitcase in the POV shot does not match at all the following view. (00:19:40)
Continuity mistake: Mrs. Kimball's wheelchair and Mrs. Kimball herself are in position and angles different in each shot during the scene of the fall; the chair faces right, left, right, and the old lady is suddenly perfectly on the ramp at the end after falling prone. (00:05:40)
Continuity mistake: When Agatha Kimball tells Amy at the piano "No, I was talking about your cologne", Andrea Marcovicci's hands both jump on the cup at the cut. She was holding it with just one hand. (00:05:00)
