Continuity mistake: The chopper takes off from Higgie's un-birthday party, looking as usual. It flies over a shore to thwart Holly's plan, and doing so it has the flotation skids from a different chopper's stock footage. It is therefore also missing the birthday banner, that is present again in the finale. (00:45:10)
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)
Revealing mistake: When the brawl in Charlie's office begins, Tom Selleck changes into his stuntman who can be seen as he quickly stands and punches a goon. (00:41:50)
Audio problem: Magnum poses as an envoy from Icepick. When he takes his feet off the desk, he says an "Okay" that the microphone struggles to pick up. (00:41:05)
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)
Audio problem: During the first match, Rick shouts "Attaboy, TC!" from the corner but Larry Manetti pops in frame during the dodge, lips closed. (00:16:05)
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)
Audio problem: When Charlie Amos says "No time to promote you" questioning TC's proposal to replace Leon, the sentence is dubbed in, having different audio quality from the rest. (00:13:55)
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)
Revealing mistake: During the crash through the fence, the front of the Ferrari has a mockup in the front; the left direction indicator falls off outright, but it is just broken when TC and the new two passengers take off. (00:04:40)
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)
