Line Of Duty fans left BAFFLED at continuity error when BMW changes to older version of the car

Line Of Duty returned in explosive fashion for the hotly-anticipated sixth series on Sunday – as fans hoped to get one step closer to discovering the identity of H.

18 months on from the events of series five, viewers saw the once tight-knit AC-12 unit in disarray in the premiere episode, but that wasn’t the only thing grabbing attention – as fans spotted a major continuity error.

As characters including new officer Joanne Davidson (Kelly MacDonald) headed to the scene of the robbery in two BMW cars, eagle-eyed fans saw one of the vehicles switch to an older version of the car.

But when the cars pulled up, the newer version of the vehicle had returned (with its grill changing from silver to black and back to silver again) – with fans taking to Twitter to ask if anyone has spotted the blunder. 

One fan wrote: ‘Poor continuity there, an older BMW estate making a brief appearance.

Another wrote: ‘Sorry what was with the BMW continuity error on #LineOfDuty ?? Screaming obvious! #LineofDuty6.’

Fellow petrol heads penned: ‘#lineofduty was thinking, that’s strange they’re using a 10+ yo BMW E61 and then mysteriously it changes to a 2020 model with same plates

One fan added: ‘Has anybody spotted the error on #LineofDuty in this latest series, episode 1???? HINT it’s twelve minutes in from the start! #bbc #tv #TVseries #lineofdutyseries #BMW’

Another wrote: ‘When did the convoy suddenly ditch one of their BMW G20 three series model for an 5 series E60 and then back again.’ 

The hit BBC show delighted viewers with several plot twists and even taught them a new acronym, with many hilariously mishearing it for something much cruder.

And although only being introduced in the first episode, new character Detective Chief Inspector Joanne Davidson certainly made her mark and left many fans with more questions than answers.

One of the stand-out new terms from Sunday’s show was CHIS, which stands for Covert Human Intelligence Sources.

However many viewers revealed that they’d be hearing the much cheekier term ‘jizz’ for the majority of the intrigue-filled episode.    

One particular scene with Davidson and DI Kate Fleming [Vicky McClure] saw them repeat the phrase several times with the women asking another officer to ‘help us locate your CHIS’.

One person tweeted: ‘This is the jizz handler?’ while someone else added: ‘Ah it’s CHIS… for half an hour I thought I’d been hearing JIZZ’ 

And another penned: ‘Everytime they said CHIS in that episode, I heard JIZZ. And they said it A LOT. And I couldn’t unhear it!’ 

The first episode of also saw several twists, perhaps most shockingly with the revelation that long-term AC-12 member Kate is now working with a new team.

While chatting to her new gaffer DCI Davidson, Kate says: ‘I got fed upon nicking coppers, I’d rather go after the psycho who murdered Gail [Vella].’

But despite seeming confident in her new role, some viewers were left wondering if all was at it seems and theorised that Kate could still be undercover for AC-12.  

Another surprise twist came in the reappearance of Terry Boyle who was used by the OCG in previous series and famously had a body hidden in his freezer.

The character, who has Downs Syndrome, was arrested after a police raid on an address and mistakingly gave the wrong name to officers when questioned.

His involvement left many fans shocked at the development, with some saying they felt sorry for him being dragged back into the criminal activity.

One person tweeted: ‘Terry Boyle deserves to be left alone after years of exploitation at the hands of the OCG. Why do I feel like this ain’t gonna end well for him?’

While another theorised: ‘So Terry Boyle had a woman in his freezer in series 5 and now his freezer is missing, I’m in too deep already.’   

Adding to the intrigue, the raid itself also became suspicious as DCI Davidson seemed to be delaying her team’s arrival when she ‘spotted’ a robbery in place.

This potentially shady move tipped her as a ‘bent copper’ for most of the hour-long show but in true Line Of Duty style things got more complex at the end.

DCI Jo was then revealed as being romantically involved with one of her staff, Farida, who had earlier reported her to DS Arnott to look into as being corrupt.

This new information caused some fans to question whether Jo really is corrupt, or just being set up by an angry ex-lover.

Elsewhere fan favourite DS Steve Arnott [Martin Compston] was seen rocking a bigger beard than usual and struggling with his pain problems from past series.  

One scene saw the officer buying lots of tablets before taking several at his flat – and washing them down with a bottle of Corona beer in an apparent nod to the current pandemic. 

Some Line Of Duty fans were also left very amused after spotting an actress who looked remarkably similar to Theresa May in Sunday night’s episode.   

Taking to social media, several people joked that the former Prime Minister, 64, had made a ‘strong and stable’ cameo in the show.

In the scene, the woman is seen stood up and taking notes while DI Kate Fleming [Vicky McClure] and her colleagues listen to a briefing from new character Detective Chief Inspector Joanne Davidson [Kelly Macdonald]. 

The actress, who is wearing a navy blue cardigan over a smart pink collared shirt, looks serious as she listens to the information in the murder investigation.  

Fans had been chomping at the bit to see what unfolds in the season premiere of Line Of Duty, with the cast and showrunner all teasing morsels of information in recent press calls. 

Martin Compston, who plays DS Steve Arnott, said: ‘I feel like the last two series have been building up to this one. There is a lot going on. There will be a lot of big questions answered. But all the drama that everyone loves will be there too!’  

Series six will follow the dynamic AC-12 trio investigating the force’s highest profile murder to date.   

Guest lead Detective Chief Inspector Joanne Davidson is assigned as the senior investigating officer on the unsolved murder case, but her suspicious conduct attracts the attention of the anti-corruption team.

Shalom Brune-Franklin, 26 — who has appeared in BBC’s Our Girl alongside Michelle Keegan — is the new addition to AC-12 as Detective Constable Chloe Bishop.

Some viewers branded the finale of the fifth series, which aired in May 2019 and drew more than nine million viewers, as an ‘anti-climax’, after it was revealed that mysterious criminal mastermind H was in fact code for four people.

So fans will be hoping the show finally reveals the fourth person’s identity — and the teaser suggests it might not be a man they are looking for.  

This series of the Jed Mercurio drama also features seven episodes, making it the longest to date. 

And speaking ahead of the first episode airing, Jed revealed ‘nobody on the show is safe’ as killing off AC-12’s three main stars ‘is never far from my thoughts’.

He told a Q&A: ‘One of things about the show is nobody is safe. It keeps the audience on the edge of their seat so I know it would be a sad day, but all the main cast realise it could be possible.’ 

While Adrian Dunbar admitted it was a ‘shock’ to see the series come together after the trailer was released earlier this month.

The actor, 62, admitted he found shooting series six ‘difficult’ as the Covid pandemic meant they had to film in a non-chronological order, due to safety measures in place.

Adrian said of filming: ‘Jed and the directors had to remind me sometimes exactly where we were because we were jumping between scenes. 

‘You know, it’s sometimes difficult how to pitch something when you’re moving, as Vicky said, between directors and episodes.
