Visible crew/equipment: At the beginning of the episode, Magnum's friend drives off in a fancy car, and Magnum is thinking about it as he gets on his own fancy car. In the door of the Ferrari you can see the reflection of set lights. (00:03:50)
Continuity mistake: Magnum follows his inner voice and gets inside Marcus' quarters. The camera follows him and he stops in front of the desk where a picture is balanced on one side on some stacked papers. In the close-up that follows, the picture is flat on top of Marcus' appointments book. (00:08:45)
Continuity mistake: Magnum's search for clues at Marcus' is interrupted by a banshee scream from the girl with glasses. In the first few shots of the sequence, Tom Selleck's left arm is never in the correct position, being low in frontal view and raised in reverse shot, doing the same movement twice in different shots, etc. (00:09:05)
Visible crew/equipment: While Magnum argues with Higgins about the planned fundraising tours, Magnum gets a crossbow from the bedroom, and when they both head to the kitchen area the three white tape marks are visible on the step/floor. (00:12:20)
Continuity mistake: Magnum takes a bottle of the infamous Coops beer from the fridge and puts it down while Higgins is doing his threatening smile routine. He puts it down with the label facing away from the camera. When he answers the phone, the bottle is again facing away from the camera, but the angle is the opposite than the earlier one. (00:13:10)
Continuity mistake: The threat about the Romanian mime troop does the trick, and Magnum stands up to go after Higgins for some begging. The cloth he's cleaning the crossbow with dangles in its length in the first shot, but it's draped over the handle in the next. (00:14:00)
Visible crew/equipment: When Magnum and Tracy are in the Ferrari after their fake date, Magnum mentions being reimbursed for dinner and breakfast, and in the shots facing the windshield the device (to secure a side camera) over Tracy's door is visible. (00:19:40)
Continuity mistake: Magnum goes around the market to show around Marcus' photo. Multiple extras, such as a man with a blue Hawaiian shirt and a kid with a white jumper with red sleeves, can be seen roaming the premises multiple times in different shots. (00:24:00)
Revealing mistake: The man who gets kicked in the face and chest by the two wicked ladies inside the building is not Tom Selleck. (00:26:45)
Continuity mistake: When the "policewoman" arrives and yells "Freeze! Police!" thumping her chest, Magnum at the bottom of the frame is getting up. In the next shot her hands are off her chest and Magnum is very far away from even the thought of getting up. (00:27:00)
Continuity mistake: Magnum groans asking Tracy Spencer "Why didn't you pull your gun?" She has both hands joined, just one hand up in the next shot. (00:27:15)
Continuity mistake: Magnum's face after the beating from the 80s girls in leggings and hairspray gets suddenly bloodied on both sides of the mouth at the end of the scene. (00:27:20)
Visible crew/equipment: Higgins leaves for a trip. Once he closes the door, Tracy hunches over to ask Magnum if it still hurts, and in her big glasses you can see the reflection of set lights. (00:29:40)
Visible crew/equipment: Aftermath of the sting gone wrong at Rose's. Tracy Spencer runs after Magnum saying "Please, just listen!" In the bottom right corner of the frame you can spot the boom mike shadow for an instant, then the operator's, following the movement of the two (and the camera's). (00:37:00)
Visible crew/equipment: When Magnum screams to Traci to get out of his life, forever, there' s a camera cut and on the left of the screen some equipment that is not supposed to be in frame is seen for a second. (00:39:50)
Continuity mistake: When Magnum says "Murder's never private", his left hand moves from the bottom to the side of the diary. (00:42:15)
Character mistake: In the opening narration, Magnum says "Take my good friend Marcus, for example. I woke up one day and realised I was 32 and I'd never had a chance to be 22." In the second part of the very pilot of the series, Magnum says to Alice "One day I woke up age 33 and realised I'd never been 23."
Plot hole: Magnum is amazingly naive in this episode, blindly believing the story about Tracy Spencer being a cop against every possible evidence of the contrary. This buffoonery aside, Tracy saves him from the two girls identifying herself as a cop, but a couple scenes later they both go meet their boss and try to set up a sting passing off as dealers of stolen goods. That does not make any sense.
