Factual error: While it is true that lithium carbonate can be used to treat depression and other psychiatric disorders, it cannot be administered in gaseous form. It is a very stable salt and only starts to form vapour at 1,310 degress Celcius. Spraying it about as a 'mood stabliser' at that temperature, as Kryten does, is going to kill everyone on the spot.
Factual error: At the beginning of the intro, the narrator says that the only way to resurrect a vampire is with a sacred rite that can only be performed once a century when the moon is in the eighth house of Aquarius. In Astrology, the eighth house is Scorpio.
Revealing mistake: Shortly after the fight with Becky, Roseanne asks Jackie to go across the street to get her something to drink, so she can smoke in secret. After Roseanne lights the cigarette and walks near the register, Jackie's plaid coat can be seen in the door's window as she waits for the next scene.
Other mistake: The fire at the used cars dealership recycles several shots from the petrol station fire in Series 6 episode 7. These include shots of burning petrol on the ground and a Renault car with the registration mark B649 CLY exploding.
Odd Man Out - S3-E6
Factual error: Near the end of the episode when Kevin and Paul are riding their bikes toward each other before they stop for a brief hello of sorts, Kevin rides past a couple cars parked on the street that were built in the early 1980's. A red Pontiac LeMans and a black Pontiac Grand Prix-both were parked in front of the 1969 Ford Thunderbird.
Factual error: When Pug comes home, Rhoda puts on a Christmas record. The record player has an automatic changer that drops the disc and then moves the arm into place. Though a small 45 rpm changer was designed as early as 1938, and this movie's set in 1942, the type Rhoda uses here wasn't around for another 20 years. (00:09:00)
Factual error: About 45 minutes into the episode, the girls' car stalls because the alternator's wire has been removed to cause this. For a car to stall like this, the battery has to be heavily drained which it would wind up being. When the killer comes up to the car, he tells her to try and start the car. She does and it turns over but doesn't start. The battery would never have enough amperage to turn over the car if it didn't have enough to keep the motor running.
Continuity mistake: Just before his twin brother appears at the window, Aulus Paulinus puts the statue he was looking at on his desk. While he is talking to his brother, the statue is gone. Then afterwards it suddenly returns to where it was.
The Killer - S1-E1
Continuity mistake: Jim's pupil and successor Copperfield is poisoned at the beginning of the episode. He screams, drawing the attention of the party guests. In the following POV shot, the guests are standing in entirely different spots in the room all of a sudden. (00:02:45)
Continuity mistake: "The Feverman": Before putting the chain around his neck, the doctor removes both his detachable collar and his black string tie. A few shots later, not only is the collar back, but he's now wearing a red ascot-style tie. Both collar and tie vanish again one shot later. (00:17:05)
Piratsy Under the Seas - S1-E1
Continuity mistake: When Jolly Roger hands the map to Dale, the map has either a dark brown border or not depending on the angle. (00:08:30)
Factual error: Teddy says that he hates the stories by Wodehouse about the stuttering Bertie Wooster. However, Wooster only had a stutter in the 1965 TV series "World of Wooster", not in the original stories or in any other adaptations such as "Jeeves and Wooster." "You Rang" is set in the 1920s, and thus 40 years too early to have seen that program on television.
Visible crew/equipment: In episode 1, "Computer Logic", there's a scene in which Austin & Michelle step into a computer convention, where a hot-shot software designer, Mr, Blaine, is delivering a sales pitch from his wheelchair. In one shot the boom microphone can be seen dipping deeply into frame.
