Revealing mistake: Throughout the episode, the makeup used to age Elisha Cook Jr. is not of the highest quality, and seems about to fall off his face in the dinner scene.
Revealing mistake: When Magnum is in the sniper's crosshair (and the following shots from that angle) you can already spot on the pillow the circular area around the detonation point of the charge that simulates a bullet - and even the little bulge of the charge itself. (00:23:35)
Revealing mistake: Looking at the reflection in TC's sunglasses and the relative staticity of the background it is quit evident that they are not flying around the building, but the chopper is landed somewhere with the cameraman doing some wiggling to shake things up a bit and give the impression of flight. (00:44:10)
Revealing mistake: When TC says "Sometimes I HATE being right" as he ends up in a shootout as he feared, the close-up is mirrored so he can be shown sitting closer to the camera. The hat's letters are backwards, of course. (00:45:30)
Revealing mistake: Magnum and the others are escaping from the cryo room; meanwhile the two baddies are by the door...but in a mirrored shot, with the letters (for instance the big "Corrosive" sign) seen in reverse. (00:43:45)
Revealing mistake: Magnum and Mrs. Ballard come out of the elevator supposedly at the same floor - the Penthouse - Virginia and the butler went to. But coming out of it, the number "4" is visible instead. (00:36:00)
Revealing mistake: Virginia before tripping the butler pushes the G button to send the elevator down. When the security guy is looking at the phony CPR scene in the monitor, the elevator is still at the floor, open doors and not moving. (00:34:40)
Revealing mistake: The security guy is checking Magnum as he appraises the cutlery and waits with his client for the rich man. And at the top of the frame of the security camera feed...the security camera that is supposedly filming. (00:14:40)
