Revealing mistake: In one of the many cartoonish scenes involving Rick, he gets utterly stunned by the weak silly airplane-spin like movie Borgnine performs on him and after a chirping birds sound effect is played, he - or rather, his stuntman - does a Ric Flair faceflop. The stuntman is wearing tennis shoes with clean rubber soles. After his scene with Higgins, Magnum arrives with TC and Rick in a headlock - Rick falls in that shot, and he is wearing patent dress shoes with black soles. (00:27:20 - 00:29:40)
Revealing mistake: When Magnum stops the car right by Higgins who is tending to the plants, there's a close-up of the car tyres raising a lot of dust - or not, actually; it's as if the tyres were vacuuming the dust in! The footage is played backwards. (00:28:05)
Revealing mistake: When Earl punches Rick in the jaw, he's wearing his beanie hat. He (or rather, Mr. Borgnine's stunt double) uses his foot to flip him over, and he is not wearing a hat. When he releases Magnum from the 'Detroit death grip', we're back to a beanie-wearing Ernst Borgnine. (00:32:00)
Revealing mistake: When Earl is carrying TC across his shoulders, Roger E. Mosley is replaced by his stunt double - you can even see his face, and he's also wearing a different belt - Mosley's is of a reddish brown, the stunt person's is dark chocolate. (00:26:20)
Revealing mistake: Mr. White Death intervenes to even the odds as Magnum and TC are getting beaten up. He grabs one guy right away and sends him flying against a wall - but the extra does not fancy headbutting a wall, and even if his character goes KO for the rest of the fight, it's obvious that he connects with the wall with both palms and the head stays inches away from it. (00:06:45)
Revealing mistake: In the fight at the wrestling match joint, both Magnum and TC's stunt doubles are with their faces in plain view when the beatdown begins and Magnum with his arms blocked kicks the bad guys away. (00:06:25)
