Continuity mistake: The very first shot of the episode after the opening shows TC's chopper with the flotation skids and serial number N58243, but when it lands on the roof it's the more familiar N1095A with no such pads. (00:01:30)
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)
Continuity mistake: When Rick throws himself at the bad guys realizing the pistol is empty, the light of the scene changes entirely. (00:46:15)
Continuity mistake: As Magnum and the unlikely bunch of characters he picked up along the way reach the roof and move up a flight of stairs, the shadows on the cement change drastically in the aerial shot. (00:44:50)
Continuity mistake: When Magnum and the girls begin their tiptap behind the camera, the Bic pen by the security guy moves between cuts without being touched. (00:39:35)
Other mistake: The bad guy in the control room gets some overhead shots of the camera that point down significantly more than the rest, but in close-ups we never see the camera alter its tilt, merely the direction it spins in, clockwise or counter.
Continuity mistake: When Magnum grabs Virginia for the 'exercise' meant to fool the camera, she trips on Farber's flipflops. When the security guy is checking the room out from the camera, the shoes and Virginia's handbag are in different positions. (00:39:10)
Other mistake: When the security guard is looking at Magnum trying to mess with the lock, the camera is on the ceiling, but the camera angle he gets on his monitor is as if the camera were level with him. (00:38:10)
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)
Continuity mistake: Virginia Fowler is entering the building on her own with the butler. Barker in the security camera footage is holding the elevator key in his left hand, but when the angle changes, it's in his right hand. (00:34:15)
Continuity mistake: When Rick is getting the print of the keys from the geriatric butler, his grip on the box changes depending on the camera angle. (00:31:05)
Audio problem: Magnum is begging Rick for a favor, and finally agrees to his conditions. He says "Will you do me the favour?" and an off-screen crunching noise is heard. But Rick is eating a sandwich, he still has it in hand. Only a second later he puts that down and grabs a crisp, which would make that kind of sound. (00:28:30)
Continuity mistake: Magnum is carrying the box to Virginia's new bungalow. From the door, they look inside and find it all messed up like the old one. Magnum is then consoling Virginia without having time to put down the box. (00:20:10)
Continuity mistake: Magnum is talking with Mr. White, hands raised, for some reason. When the camera is behind Tom Selleck, his two forefingers of the right hand are close together, while filmed from the front they distant enough to keep the index out of frame entirely. (00:15:30)
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)
Continuity mistake: The chauffeur gets a phone call while Magnum and his client is in the elevator. In wide shot he's holding the wheel with the hand at the top, but he's waiting with the hand on 9 o' clock in the closer view, and back on top as it switches to the same angle as before. (00:13:20)
Continuity mistake: The guy on top of the building passes TC an envelope with his fee. The envelop is facing a different direction between shots - it opens with the flap towards him in the first one, towards TC in the next. (00:02:40)
Revealing mistake: When Higgins rolls over the man that got shot in the struggle, the 'dead' person raises his evidently not-so-dead-yet right leg to avoid rolling back to the side. (00:25:00)
