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)
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)
Visible crew/equipment: Straker brings Paul Foster to SHADO Control and takes him into his office, then just as Straker says, "Ok, Alec, wheel them in," the boom microphone pokes into the shot at the left side of the screen. (00:44:05)
