Visible crew/equipment: During the final chase, Jaclyn Smith's double stuntwoman is extremely evident. (00:43:45)
The Bermuda Triangle Crisis - S2-E4
Revealing mistake: When Wonder Woman drops a mine into the water, she's supposed to be dropping it into the ocean. However, you can see a drain plug of some sort in the background and the "ocean" is obviously a pool, or similar.
Vampire Bats and Scaredy Cats - S2-E2
Continuity mistake: When Lisa's uncle shows her her grand-father's picture, it changes from one shot to another.
Go Fight City Hall -- To the Death! - S1-E1
Factual error: When Quincy, the well-experienced doctor, uses the defibrillator to bring a just deceased man back to life, he never put some gel on the paddles in the first place. (00:15:25)
Diana Ross - S4-E23
Continuity mistake: When Diana Ross finishes her first song, the bird has both his feet on the ground; in the next shot, the bird has one leg raised, without enough time passing to do so. (00:08:45)
The Robbery - S4-E4
Plot hole: Towards the end, Jake (Shirley's boyfriend), hangs the girls on a coat rack by the hoods of their coats. They try a few comical ways of trying to escape, when they could have simply unbuttoned their coats and slip away.
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.
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.
Revealing mistake: The opening scene was shot twice, complete with a rear-end automobile collision in the foreground for both takes. The initial collision destroyed the taillights of the first car and the headlights of the second car and ruptured the second car's radiator on impact, spilling its contents into the street. The production crew attempted to sweep away the debris with a broom before the scene was reshot. If you examine the roadway before the two cars appear in this scene, you will see a prominent splatter on the pavement that has been swept with a broom almost precisely where the cars impact again moments later.
Revealing mistake: Jamie prepares to split a giant heavy log in two, with her bionic arm, so that it will fit into her fireplace. Just as her arm comes down, you can see the middle seam where the log was pre-cut for the shot, so that it easily breaks in two. (00:00:30)
Continuity mistake: In the close-up of putting the lids on the bottles, Mat's hands have 5 fingers (briefly done by a real person instead of the puppets). However, throughout the series, the duo is consistently 4-fingered - and that includes other close-ups that were also created with real hands briefly replacing the animation.
Revealing mistake: The set where Augustus visits Agrippa on Lesbos for reconciliation is the same set where Augustus already was before - he was there earlier, reading the news of Marcellus' death while he was away from Rome to visit the Eastern provinces. But as stated, he had not visited Lesbos at all, because he and Agrippa had temporarily fallen out. (00:39:30 - 00:41:30)
