Continuity mistake: When Magnum takes one of the outrigger canoes, the paddle he uses to paddle away from the island has a normal handle, but in the overhead wide shot facing Magnum's back, he's using a paddle with a T-grip handle, then it's back to the paddle with a normal handle in following shots. (00:21:05)
Continuity mistake: While Norm Vogel is meeting with a man at the Hawaii Museum, getting information about the tiny shells from Alea's necklace, in the wide shot we see the map with the island of Molokai, when they walk over to it. In the next closeup of the map, there are now three small (fictional) islands north of the island of Molokai, which have been deliberately drawn onto the map for this closeup. (00:32:50)
Continuity mistake: While Rick goes around asking if anyone's seen Magnum, there's a closeup of Rita as she pulls back one side of her blouse to admire her new tattoo, and in this closeup she's wearing a watch with a silver face and her new tattoo has a horizontal curve, but in the next shot Rita's watch is a smaller all black style and the tattoo is now more vertical. (00:33:35)
Continuity mistake: At Agent Estin's office, Bryant is wearing a plaid shirt with bold vertical pastel stripes, and pink stripes at the edges of his collar, but during the drive home in TC's van, the vertical stripes on Bryant's shirt have changed, though it still has the same pattern. Note the blue stripes at the edges of his collar. (00:06:30 - 00:08:40)
Revealing mistake: When TC and Bryant leave Agent Estin's office it cuts to TC's van on the highway, and as we hear Magnum in the voiceover talking about his dad's advice, "to call the monsters out," we can see the shadow of the helicopter filming this footage. (00:08:20)
Continuity mistake: When TC gets off the phone he tells the others that somebody must go to the Sea Palms Hotel, room 401. During their joint mission, Magnum responds to TC on the walkie and tells him he'll call back when he's in the room. Then Magnum enters room 1201, not room 401 as the kidnappers had instructed, right before the kidnappers call room 1201. (00:37:00 - 00:38:30)
Revealing mistake: One of the party guests opens the door of the fridge and you can see behind the set instead of looking into the fridge. (00:32:40)
Continuity mistake: When Higgins and Del Haynes leave the house Higgins is wearing his camo vest and hat, which he wears throughout the episode until the end. Though the style of his hat and vest remain the same, the actual camouflage pattern on both the hat and vest changes. There are two different hats and three different vests. The changes even occur between shots, such as during the scene at the end when Higgins returns to the estate.
On the Fly - S7-E15
Visible crew/equipment: After Magnum realises TC has been shot, in the following wide shot with TC in the hospital bed, two black T-marks are visible on the floor, where Magnum stands, then a third T-mark is visible on the floor closer to the TV. (00:05:40)
On the Fly - S7-E15
Visible crew/equipment: While Higgins is standing beside TC's hospital bed there's a boom pole and mic hovering low in the area of Higgins' legs, and it can be seen in the two wide shots from behind Higgins, especially when Rick mentions the noontime news. (00:06:40)
On the Fly - S7-E15
Visible crew/equipment: When Magnum successfully lands the plane he starts shouting about the brakes, then in the following shot of "Mac" lying in the hospital bed, the black T-mark is visible on the floor, in front of Higgins. (00:44:25)
Continuity mistake: When Magnum answers the phone call from John Costa he's wearing the new shirt with a striped colorful pattern, which was a birthday present from his mother. During Magnum's introduction to Costa in the alley, the style of Magnum's shirt is the same, but the striped pattern has changed. Then the pattern changes again when Magnum returns home bruised. (00:26:25)
Continuity mistake: While Magnum is at Page's desk looking at the NYC arrest report, it cuts to Doheny at the estate as he opens his suitcase and lifts the gold picture frame. The problem is, in this shot the black easel back has been inserted within the gold frame upside down, note the frame's open end. Then in the next shot, the easel back is inserted properly within the frame. (00:33:00)
Infinity and Jelly Doughnuts - S8-E1
Visible crew/equipment: While Higgins rushes to the waiting room he stops in the hall to wipe the grin off his face, and when he enters with the news, the taped T-mark is visible on the floor in front of Rick and Carol. (00:11:40)
Infinity and Jelly Doughnuts - S8-E1
Continuity mistake: When Ron Templeton hands Magnum the manila envelope, in the shot facing Magnum as he pulls the photo out of the envelope, we can easily see the image from the back side of the photograph. In this shot the man in the photo is wearing a suit jacket, white shirt, tie, with nothing on his head, but in the next closeup of the photograph Quang Ki is wearing a uniform and cap. The same thing happens again later, when Magnum is in his VA hospital room. (00:32:30 - 00:36:30)
Infinity and Jelly Doughnuts - S8-E1
Visible crew/equipment: After they talk to Nick about Father Timothy it cuts to Maggie hounding Magnum not to go after Quang Ki. Just as they all turn the corner to walk into Magnum's VA hospital room, the nurses station is in the background at the right side of the screen, and there's lighting equipment and a director's chair visible. Also, after Magnum agrees to give Ron time to find Quang Ki, when it cuts to Katherine talking on the phone, we can see Larry Manetti just standing in the background at the right side of the screen, waiting for his cue to rush into the study. (00:34:10 - 00:35:25)
Visible crew/equipment: When Rosita pulls Higgins up to the dance floor without a "diagram of the steps," just as Higgins begins to dance, the white T-mark on the floor is visible at the bottom of the screen in two shots of the same angle. (00:11:55)
Visible crew/equipment: At the club, when Magnum walks over to Higgins to stop the confrontation between him and Torres, just as Magnum and Higgins trade comments with each other, a T-mark is visible on the floor at the bottom of the screen. (00:12:50)
Visible crew/equipment: While Rita is wearing a wire during dinner at the restaurant, when Magnum walks in a white T-mark is visible on the floor under the tablecloth, at the bottom of the screen. (00:38:20)
Tigers Fan - S8-E4
Continuity mistake: At the guesthouse, when TC is telling Magnum about his "modern coaching" videotaping technique, in the wide shot Rick is standing beside the TV with the VCR on top, but in the closeup it's an entirely different TV, with no visible VCR atop it. (00:12:20)
