The Feminum Mystique: Part 2 - S1-E6
Visible crew/equipment: After the Nazis are defeated on Paradise Island, Queen Hippolyta tells her daughters that she has plans for those Nazis, and at the start of the next shot the set equipment's c-stand is visible at the left side of the screen (widescreen version).
Revealing mistake: During the final chase, Jaclyn Smith's double stuntwoman is extremely evident. (00:43:45)
Continuity mistake: Near the end of the show, the squadron has to land on a carrier deck. The shots from the sky go back and forth between a straight deck carrier and an angled carrier deck. Also, an angled carrier wasn't put into use until the early 50's by the British, Black Sheep takes place in WWII.
K is for Kill: The Tiger Awakes (1) - S2-E8
Visible crew/equipment: Steed is seen driving along with Purdey and Gambit in rural France. The camera was probably mounted on the front passenger side door, pointing in. As they near their destination, the camera pans to reveal a farm house, and as it pans, a professional-looking microphone can be seen sitting on the dashboard.
Other mistake: Jamie, pretending to be Lisa, goes to the safe, and turns the dial with her bionic right hand, but the back and forth shots show her listening to the clicks with the same hand she dials with. (00:36:40)
