Revealing mistake: Magnum neutralizes the pursuer at the gas station jacking his car. In the close-up of the wheels spinning with no traction and then stopping, the hubcap is in pristine condition, but in the next one, it sports a dent already from a previous take. (00:15:20)
Revealing mistake: When the guy tricked by Magnum gets out of the car, check out of the very right side of the frame. You can actually see the hand of one crew member releasing the garage jack's lock, so that, when the car is kicked, the relatively light impact is enough to release the hydraulic lift and make the car comically bounce back on the ground. (00:15:25)
Revealing mistake: During the jogging phase, which may not be hazardous but surely is defatigating, Tom Selleck is replaced consistently and noticeably (except the close-ups, of course) by his stunt double Tom Lupo. (00:40:35)
Revealing mistake: In the opening shot, while Carol Ann is calmly jogging, moving along right beside her is the filming vehicle's shadow, visible at the bottom of the screen, then Carol Ann exits the park. (00:01:30)
Revealing mistake: In the photo Billy Joe shows Magnum, his sister's image appears superimposed on a background - which is also quite unlikely from anyone near Shamrock, TX, and more like a lush Hawaiian scenery. (00:04:30)
Revealing mistake: During the kendo sparring, on the breastplate of the kendogu you can see the reflection of the set lights, practically all the time. (00:11:00)
Revealing mistake: The chopper lands and an upset Billy Joe Bob disembarks. A low standard for body doubles is set when you realise that TC has been replaced by some white dude wearing a bandit scarf on his face and sunglasses. (00:15:00)
Revealing mistake: Magnum is back from his meeting with Ito. When TC from his seat reaches for the heli door, you can spot he's someone else wearing a ski mask. (00:33:45)
Revealing mistake: Billy Joe Bob steals the Ferrari, but the interior shot of the car with him switching gears is stock footage; the person in it has sneakers on like Magnum, not James Whitmore Jr.'s cowboy boots. (00:37:00)
Revealing mistake: After wiring TC's chopper, Billy Joe Bob puts the headset on and looks behind him. When he turns his head to look, you can see that on the right pad there's something handwritten with an ink marker on it; "D. JONES." Makes no sense on TC's chopper, but much more sense when you know that the aerial coordinator and helicopter pilot for this season of the show is named in fact J. David Jones. (00:40:45)
Revealing mistake: When Billy Joe Bob downs the 3 Japanese goons hitting them with the skid of the chopper, only two (at most) are hit and on the chest, the other (again, at most) gets the impact of the other two knocked against him, and all of them land on soft grass. Yet of course they are unconscious and KTFO for good. (00:43:30)
Revealing mistake: When the masked Hawaiian hits Magnum in the back with the club, for a second you can see distinctly Tom Lupo (stunt double) 's face instead of Tom Selleck's. (00:22:25)
Revealing mistake: In the wider shot, the dead body the police covers has much more of a receding hairline than in the close-up. (00:23:55)
The Woman on the Beach - S2-E3
Revealing mistake: Lisa is hiding from Ellison inside the potting shed; the camera is following him, and you can see him move his head avoiding a big leaf that the camera itself pushes, showing its presence. (00:44:00)
The Woman on the Beach - S2-E3
Revealing mistake: Rick just got shot and Magnum asks him if he's OK. When he answers, you can see that Larry Manetti is not lying in a random spot on the lawn, but on a rug the same color of the grass. (00:44:55)
Revealing mistake: When Magnum socks the detective, The Turk starts going down with the punch almost before Magnum swings. (00:33:35)
Revealing mistake: To make his escape from the church, Magnum turns the Mercedes around. You can distinctly see at the driver's seat the driver, which is not Tom Selleck but someone who seems to be wearing fake moustache. (01:10:50)
Revealing mistake: When Magnum shoots the agent in front of Bully's Tattoo Shop, he gets propelled in the air at impossible distance in a very fake trajectory with obvious wirework. (01:31:50)
Revealing mistake: Magnum finds inside of the mysterious woman's villa a folder about Higgins. On the right side, there is some insurance document stuff that is pure filler. On the left side (but that one fades fast so you may need to pause for that) you can see that truly she has him scouted thoroughly, because it contains information about not just Higgins, but...John Hillerman and his acting career. (00:30:10)
Revealing mistake: When the bad guys show up at the main door surprising Higgins, the background (save a couple plants at the side of the door) is matte painting. (00:42:50)
