The plot details for the Black Mirror film may have leaked

If true, it's 312 minutes long which might confirm a big theory...

Details have been thin on the ground regarding the return of Black Mirror, with constantly swirling rumours that the upcoming Christmas special of the show would star Miley Cyrus and would somehow be an interactive episode. All signs seem to point to an episode called 'Bandersnatch' dropping on Friday 28 December, and eagle-eyed Netflix users have even spotted a placeholder in the back end of the streaming service. Now over on Reddit's r/BlackMirror, fans think they have cracked even more info. They've found this post from the Korean Media Ratings Board: Don't worry if you can't read Korean - the plot synopsis on there has been translated as:

A young programmer makes a fantasy novel into a game. Soon, reality and the virtual world are mixed and start to create confusion.

This would definitely fit into the rumours of it being an 'interactive' experience - those classic text-based games from the 1980s would be the perfect device if Charlie Brooker and co were trying to do some sort of TV equivalent of Choose Your Own Adventure. Another interesting bit of information from the Korean Media Ratings Board is that it says that the episode is a whopping 312 minutes long! That would be insane if it was true - but if indeed it is an interactive episode, this would make a lot of sense with all the various different pathways and options we guess that you can go down. Either that, or there's a whole new series of six episodes actually coming shortly. Other unconfirmed details that have dribbled out other the last few months include this poster appearing on Twitter, which fits with the retro adventure game theme: https://twitter.com/xiurongg/status/1066929655146401792 Back in April, set photos also appeared to confirm the early 1980s setting. https://twitter.com/stevieboywise/status/988399660493688832 Series four of Black Mirror hit Netflix on 29 December last year - let's hope we get a similar post-Christmas treat this year...
