Black Mirror Bandersnatch themed pop-up shop appears in Birmingham
People across the globe have been gripped to their TV screens since interactive Black Mirror episode Bandersnatch came to Netflix.
And now a series of mysterious eighties-themed shops have appeared across the UK with references to the hit show - and there's one in Birmingham.
Social media users spotted the pop-up stores in the second city and London, fitted out with retro signs and records, as well as posters for fictional games made by Tuckersoft, the games company at the centre of the show.
Pictures also show Bandersnatch posters in the windows, with comic books relating to previous episodes San Junipero and USS Callister.
Neither shops are open to the public, with signs reading "be right back" on the doors.
The apparent promotional stunt follows the launch of a website to accompany the show, in which fans are able to play one of the fictional video games from the episode.
Netflix has not immediately responded to requests for comment on the appearance of the stores.
The choose-your-own-adventure episode of Charlie Brooker's long-running sci-fi series is set in 1984 and has proven enormously popular since its release in December.
Starring Fionn Whitehead, Will Poulter and Asim Chaudhry, the episode follows young programmed Stefan Butler who is adapting a fantasy choose-your-own-adventure novel into a video game in 1984.
The show allows viewers to choose what decisions Colin makes at various points in the narrative. The average viewing is 90 minutes, though the quickest path ends after 40 minutes, and at least one path results in a two and a half-hour viewing experience.
However, following a massive social media reaction to the programme, actor Will Poulter, who plays games developer Colin Ritman, announced he would be leaving Twitter to protect his mental health.
"I accept all criticisms and it's been a delight to learn that so many of you enjoyed what many people worked very hard to produce!
"As we all know there is a balance to be struck in our engagements with social media," he said as he announced his decision.
"There are positives to enjoy and inevitable negatives that are best avoided," the Bafta-winning actor added.
