WATCH: New Trailer Confirms 'Black Mirror' Standalone Film Will Drop This Week

Black Mirror has shared a trailer for its latest installment, Bandersnatch, confirming that it will debut on Netflix tomorrow (December 28).

The typically-cryptic trailer, which brands Bandersnatch a "Black Mirror event," suggests that Bandersnatch will revolve around a young video game designer (Dunkirk's Fionn Whitehead) whose mental wellbeing is affected by the interactive game he is working on.

Whitehead's co-stars in the trailer — which is soundtracked by Frankie Goes to Hollywood's iconic '1984 hit "Relax" — include Will Poulter (The Revenant), Alice Lowe (Sherlock), and Asim Chaudhry (People Just Do Nothing).

Netflix and Black Mirror creator Charlie Brooker are otherwise keeping tight-lipped about Bandersnatch, but a landing page for the title on Netflix describes it as a "film" rather than a standard episode of the dystopian-themed series.

It's been widely rumored that Bandersnatch will be an interactive installment which allows viewers to decide how the narrative unfolds in the style of a choose-your-own-adventure book. IndieWire reported last week that director David Slade has readied a massive 312 minutes' worth of footage for viewers to navigate.

A leaked plot synopsis for Bandersnatch reportedly teases: "A young programmer makes a fantasy novel into a game. Soon, reality and virtual world are mixed and start to create confusion."

Intriguingly, Bandersnatch shares its title with a 1984 video game which was developed by Imagine Software, but never made available to the public.

But at this stage, we only really know one thing for certain: we'll have to wait until Bandersnatch debuts tomorrow to find out what it's about, and exactly how the film works.
