Factual error: The Audi Quattro used throughout the show has single unit rectangle type headlights. These type of headlamps were not used until the 1983 model year for that car. The earlier type were of four smaller separate square headlights.

Factual error: Episode 3 - the white Ford transit van used in the chase at the start of the show is a 1983 model.

Factual error: When Alex's mother opens her front door to her, an Austin Maestro drives past the house. These did not start production until 1983.

Factual error: In episode 5, have we moved on into 1982? "Golden Brown" by The Stranglers and "Ghosts" by Japan are used. Alex's wall chart still has her in 1981, to the best of my knowledge. These two songs were not released that year.

Factual error: During the motorbike chase at the start, the Audi screeches around a corner and narrowly misses a pedestrian. When Gene shouts "what's up with you this morning, you haven't got the decorators in again.", modern day vehicles including a white LDV pickup truck (you can tell by the grille badge) can be seen in the background.

Factual error: In Episode 5, when Chris and Ray pull away in the green car to Garside workshops, a white modern day Mercedes Sprinter van is visible behind them (immediately in front of the red Vauxhall Cavalier that drives past which, incidentally, is also out of place for 1981). Submitted by UKFilmFan

Factual error: In Episode 6 when everyone is getting into the Audi, there is a MK4 blue Ford Escort in the background which wasn't manufactured until 85-86.

Factual error: Yet another 1983 model transit van can be seen in episode 5 the third one in this series.

Factual error: The Vauxhall Cavalier seen in episode 6 wasn't on sale until September 1981.

Factual error: While the police are in the nightclub, the Human League's song "Don't You Want Me" can be heard playing. This was the Christmas number one in 1981, and wouldn't have been released during the summer.

Factual error: In episode two in the nightclub, after Visage have performed "Fade to Grey," their lead singer Steve Strange says, "I hope you enjoyed our new single, 'Fade to Grey.'" "Fade to Grey" was in fact a chart hit in the Autumn of 1980, so would have been old news in the Summer of 1981.

Factual error: In episode 5, an austin maestro van can be seen parked outside the police station. These did not start production until 1984.

Factual error: In episode two, "Souvenir" by OMD was featured. It was not released until a month after the royal wedding that year.

Factual error: During a scene in ep 3 when Gene and Alex are talking in the police station, a poster from the 1981 Bond film For Your Eyes Only can be seen in the far distance. This is correct, and 'in period' for July 1981. However, next to it, on the left, is a promotional photo of Kelly LeBrock in a red dress taken for the film Weird Science which was released in 1985.

Factual error: I can remember the early 80s. The country was in recession and there were certainly no Thatcherite yuppies about. They didn't show until 1985/86 onwards.

Factual error: One of the songs played on the boat party is too early for july 1981. "Ay Ay Ay Ay Mosey" by Modern Romance was a Christmas time hit that year.

Continuity: In episode one, Alex Drake logs on to the computer in Gene Hunt's office. A shot shows the date: 17-07-1981. However, on a wall calendar Alex creates at her flat, the date of July 20th 1981 is circled, with the word "ARRIVED" written in large letters. That implies she arrived in 1981 on July 20th and not the 17th. So, which is the correct date, and what happened to the 18th and 19th July 1981?

Plot hole: In episode 2, Alex Drake and the property developer Moore go to the Blitz club in Covent Garden, London. This club is well documented as having a very strict dress code with reports of people being turned away for very obscure reasons. Even "making an effort" wouldn't have been enough to gain entry. Everyone in the club, except Alex Drake and Moore, was "dressed up" in what came to be called "New Romantic" outfits, including two (off duty) members of Alex's team. It would've been impossible for Alex Drake or Moore to have entered the club wearing the "normal" clothes they had been wearing in the previous scene in the wine bar.

Factual error: In episode one, Alex Drake goes into Gene Hunt's office and tries to log on using the computer she finds there. The computer shows a specific date: 17-07-81. If the computer is an IBM PC (as it appears to be) then the IBM Model 5150 Personal Computer did not go on sale until August 12th 1981, almost a month later.

Factual error: Two police vehicles used in this show were made after July 1981. The transit van is a post-1983 model, and the Gord Granada MK2 is a facelift model which was not made until the autumn of 1981.
