Continuity mistake: When Magnum encounters his secretary and he just won't let go of her hand, in the frontal views of Tom Selleck he has his fingertips curled, while in the reverse shots the fingers are straight and don't rise above the side of her hand. (00:19:00)
Continuity mistake: Harry MacKenzie gets two big splotches of cake on his suit. Dances with his niece, and then comes back to the buffet table taunting his nephew. No (or at least, very little) splotches at first, but in the closer view his suit is all soiled again. (00:06:20)
Continuity mistake: Rick and TC are at the wedding buffet. Behind them as they toast in memoriam of Magnum there is a dancing couple. She has a pink hat and her date has a yellow jacket. There's also a black guy in a brown jacket busting some groovy moves of dad dance. Both are also behind Higgins as he arrives, though. The couple also walks back and forth padding the background in the rest of the scene. (00:03:50)
