In this groundbreaking interactive film from the world of Black Mirror, a young programmer's reality begins to dangerously blur with the game he is creating. Fionn Whitehead stars as Stefan Butler, a troubled but brilliant coder in 1984 who is obsessed with adapting a fantastical and labyrinthine choose-your-own-adventure novel, "Bandersnatch," into a revolutionary video game. As Stefan works under the intense pressure of a looming deadline for a demanding company run by Asim Chaudhry, he finds guidance from his idol, the charismatic and rebellious rockstar game designer Colin Ritman, played by Will Poulter. The deeper Stefan delves into the coding, the more he is plagued by fractured memories of his mother's death and a gnawing sense that his choices are not entirely his own. This sci-fi mystery drama, directed by David Slade, plunges viewers into a psychological labyrinth where every decision branches the narrative, challenging both Stefan and the audience to question the nature of free will, sanity, and the very fabric of his reality.
