As if 2018 wasn't enough like a Black Mirror episode already.
People living in Croyden, a suburb of London, received letters informing them that Black Mirror was going to be filming in their area.

AS IF BLACK MIRROR IS FILMING IN CROYDON
The set dressing appears to have taken Croydon back to the 1980s, complete with Wimpy Burger and an old-timey WHSmiths.

Love casually walking pass the Black Mirror set assembly in Croydon on my lunch break. Today I spotted a Wimpy being assembled.

1980s @WHSmith - part of the set for @blackmirror round the corner from our gaff in #Croydon - in fact they seem to be creating a whole 80s high street with Chelsea Girl, Wimpy and travel agents. Love it!

Nick Walker
Apparently they are filming a Black Mirror set in The Past, so naturally they're in Croydon. See vintage WH Smith and Chelsea Girl.

Can confirm for @WHS_Carpet that there does seem to be a grubby carpet, but who knows if that will be part of the plot.

Could someone nip into the #Croydon #BlackMirror 1984 WH Smith's & get me a couple of LP record boxes (blue), a turntable mounted record cleaning brush, a £10 record token & a copy of David Sylvian's 'Brilliant Trees' album (it's number 11 in the Chart racks) thanks.
There also appears to be a title for the episode, "Bandersnatch."

@oliviat_93 Hi Olivia. Black Mirror is also filmed today and tomorrow at One Croydon.
"Bandersnatch" is a reference to a creature which appears in the Lewis Caroll poem "The Hunting of the Snark." Just how this beast will appear in dystopian-tech form remains to be seen.
