Identified - S1-E1
Revealing mistake: When Sky One is launched, Peter replies, "Airborne, position 0-2-0 red," and in the following exterior close-up of Sky One, the four dark wires holding the aircraft are too obvious in this particular close-up. (00:31:10)
Revealing mistake: Due to re-used special effects footage, the submersible Sky One fighter, whenever it launched from the ocean at night, always took off under a full moon. (00:07:50)
Revealing mistake: Another piece of stock footage used throughout the series was a shot of the shiny metal sign for Harlington-Straker Studios. The clock on the side of a building is reflected in the sign's surface, always showing the same time of day - so it's 1:50 every time Straker drives by. (00:24:00)
The Cat with Ten Lives - S1-E3
Revealing mistake: Jim awakens alone in his car with the Siamese cat, and when he rushes out shouting for Jean, there are two black rods under the car's doors. But as soon as Jim gets back into his car, the rods vanish between shots. (00:21:55)
The Cat with Ten Lives - S1-E3
Revealing mistake: Jim Regan waits inside Paul's car, then attacks him. When they exit the car, the door is up without a rod. But when they stand beside the car, there's a black rod holding the door up. (00:37:40)
A Question of Priorities - S1-E5
Revealing mistake: After SHADO Control alerts all ground radar to the red alert, when Sky One is launched, there are exterior close-ups of Sky One airborne, and the four wires supporting the aircraft are much too visible in these close-ups.
Revealing mistake: At the start, when the surfaced SkyDiver searches for Atlantica survivors, in Waterman's close-ups SkyDiver's surface is semi-transparent. Later, when Straker is aboard SkyDiver, it happens again in his close-ups. (00:02:35 - 00:04:40)
Revealing mistake: When Foster arrives at Straker's car, there's a black rod under the car's door holding it up that should not be there.
Revealing mistake: Straker and Foster take off for the moon in a large red hovercraft which, even though it's launching in broad daylight, doesn't cast any shadow. (00:12:00)
Flight Path - S1-E15
Revealing mistake: When the mobile-units leave the transport carrier, you can see that both are being "driven" by dolls. (00:22:00)
Revealing mistake: While Straker and Col. Lake enter the studio lot, they make a few stops, then exit the car; the silver metal rods holding the doors up are visible in a few shots. (00:16:50 - 00:18:50)
Revealing mistake: When Straker and Col. Lake stop to check out the frozen people (fixed like statues), Lake spots a bird frozen in midair, and in the bird's close-ups the multiple wires (more than six) holding the fake bird are visible. (00:18:40)
Revealing mistake: In this episode the aliens with the help of 'turncoat' Turner have frozen a moment in time in which they will attack and destroy SHADO HQ. Everything and everyone is frozen in place - except for the guy in the background walking across the road during Straker's and Turner's 'car' chase in the 'Harlington/Straker' go carts.
Revealing mistake: In the interior shots of Mobile 1's cockpit, we see that there's a crew of 3 and that the pilot is black. But in shots of the exterior (miniature model stock footage), there's only one occupant, a pilot, and it's a doll with distinctively Caucasian features. (00:26:30)
Revealing mistake: While Straker, Foster and Dr. Jackson are standing over Catherine's body at the end, the "dead" woman's eyelids are twitching. (00:46:30)
Revealing mistake: While the bomb is being transported into space, when Paul arrives at the hospital, the metal rod holding the door is visible.
