Black Mirror season 6 saved some of the best actors in its ensemble for the cast of the finale episode, “Demon 79.” Set in Northern England in the titular year, “Demon 79” is a horror-styled episode of Black Mirror in which a timid sales assistant is tasked with committing unspeakable acts in order to prevent a catastrophe. Stylistically, the episode is modeled after classic Italian giallo films from legendary directors like Dario Argento. “Demon 79” is written by series creator Charlie Brooker and Ms. Marvel head writer Bisha K. Ali and directed by Toby Haynes, who previously helmed the acclaimed Black Mirror season 4 premiere episode, “USS Callister.”

From Breaking Bad’s Aaron Paul to Schitt’s Creek’s Annie Murphy to House of Cards’ Kate Mara, the cast of Black Mirror season 6 is full of huge names. The finale episode, “Demon 79,” saved some of the season’s best actors for last.
