Continuity mistake: Throughout the episode, which covers a timespan of a couple of weeks, the various patrons of the bar/club where the fights take place for the most part are around for every match, which is not out of the ordinary but...wearing the same clothes too, that's more unusual.
Continuity mistake: When Higgins calls "Buster" and "Bobby K", a strong shadow appears on his forehead in the wider angles, nothing of the sort in close-ups. (00:47:35)
Continuity mistake: Magnum is talking with the landlady in Chicago. He sneaks a peek of the Tigers game on TV. In the wider angle the newspaper in front of the TV is folded revealing different letters than in the close-ups, where it's tightly pressed. (00:19:25)
Continuity mistake: Claude rings a cowbell to announce the contenders. Amongst the patrons, recognizable and featured prominently is a local girl with a brown dress and white shoulderstraps. She is shouting and cheering in a frontal view, drink in hand, but she is also sitting in another seat, smoking, in the shots from behind. (00:14:50)
Continuity mistake: TC is accepted as replacement and tells Claude the announcer his boxing credentials. During the wide shots, Shannen Doherty's hair runs to the sleeve of her shirt, does not in close-ups. (00:14:00)
Continuity mistake: Shannen Doherty does some fine emotional blackmail on TC chasing him as he is leaving after just finding out about the boxing being of the bareknuckle kind. During this scene TC's boot on his chest changes orientation without being touched, from tip to the left ("You just gotta help me") to right ("Do you know how bad he can get hurt?") to left again. (00:13:15)
Continuity mistake: First scene in Higgins' study. Leon Platt is determined to go on with his fights even injured. He has his good hand on his daughter Ima's shoulder. She tells him "No daddy, you can't!" as he removes the hand, but in the following close-up on Shannen Doherty, the hand is back on the shoulder. (00:08:25)
Continuity mistake: Higgins through the intercom asks "TC, why are you here?" TC lowers his left hand - he had his thumb near the intercom button before, now he put it on the card. New shot, and he's back sticking his thumb up. (00:06:25)
Squeeze Play - S4-E7
Continuity mistake: In the finale, Magnum is playing a solitaire. On the desk, the card on top row is an ace, then there are from right to left a 6 of hearts, a Jack of hearts, two spaces with cards face down, and a 5. When the village idiot makes Magnum turn the queen, he does it picking it between an 8 of hearts and a Jack of clubs that were not there before. (00:45:30)
Squeeze Play - S4-E7
Continuity mistake: During Magnum's final run to win the game, the person with the ball changes; it's either a white guy in the vicinity of second base, or a black outfielder by the fence. (00:43:40)
Squeeze Play - S4-E7
Continuity mistake: At the 9th inning, Rick pitches and manages to get a triple play. The last shot before we see the scoreboard though is of Rick walking back to the bench, with his catcher mask, which was the role he played earlier. (00:38:25)
Continuity mistake: During the surf ski race, Magnum is wearing sunglasses or not, and his paddle goes from white blades to red blades, back and forth several times. (00:42:15)
Continuity mistake: Magnum asks Higgins "In the meantime, you're just gonna sit there sipping brandy, being terribly British?" Higgins answers "Yes!", cut to Magnum, hands crossed, then cut to Higgins finishing his glass, and then, all of a sudden and with the clock ticking all the way through in continuity, Magnum too is sitting there with a glass of brandy in hand. (00:31:35)
Continuity mistake: When Magnum says "Ah forget it" while TC and Rick are toweling him, there's a racer behind them who hops all happy. Next shot and she's waving the towel she had around her neck. (00:43:40)
Continuity mistake: Magnum during the surf ski race wears two different hats; first we see his Tigers hat (white logo), but then he has the yellow logo Da Nang hat - which he lost in the ocean during the season opener when the two "turkeys" capsized his craft. (00:42:00)
Continuity mistake: Magnum speaks to Higgins in the study after the romantic dinner mix-up. The collar of his jacket is straight all the way up in wide shots, and loose in Tom Selleck's close-ups. (00:27:40)
Continuity mistake: Magnum approaches Vivian and Higgins' table carrying an oar; during this wide shot the table has direct sunlight all over, but in other camera angles they are in the shade. (00:10:55)
Continuity mistake: Higgins outside the British shop is stammering. He says "But I..." and a blonde with sunglasses and a hair clip quickly walks behind him - nobody was walking towards them from that direction in the establishing shot. When a wider angle is again presented, there she is; that woman is approaching from that same direction. (00:07:15)
Continuity mistake: Magnum sits on the couch's arm, by one of the sisters who is holding Higgins' book in her lap. On her lap, under the book, there's the handkerchief she used when she was having tea. In the closer angle, there's no hankie, while Madge's is open wider. (00:18:20)
