It's not even been a week since 'Black Mirror: Bandersnatch' arrived on Netflix but already it has proved a major talking point with many viewers watching multiple times to try and test the different alternative endings. (You can read our review here.)

'Bandersnatch' is set in 1984 and follows a young programmer who begins to question reality as he adapts a sprawling fantasy novel into a video game. What makes it stand out is that it is an interactive story where the viewer gets to decide the choices of the main character, leading to many various outcomes.

The detail that went into pulling something like this off is truly impressive and it was no easy task for anyone concerned, from creators Charlie Brooker and Annabel Jones devising the story to the actors who had to bear in mind which version they were in at all times as well as the editors who had to put it all together.

Netflix have released two behind-the-scenes videos featuring interviews with Brooker and Jones as well as members of the creative team including Irish film & TV editor Tony Kearns.
